Definitions
- the invention relates to a method and an apparatus for treating obesity and controlling weight gain in mammals, and more specifically, to a gastric vest placed around a stomach or modified stomach to cause a reduced desire for eating, for treating obesity and for controlling weight gain in mammals.
- Obesity is the accumulation of excess fat on the body, and is defined as having a body mass index (BMI) of greater than 30.
- BMI body mass index
- Many serious long-term health consequences are associated with obesity, such as, hypertension, diabetes, coronary artery disease, stroke, congestive heart failure, venous disease, multiple orthopedic problems, pulmonary insufficiency, sleep apnea and cancers with markedly decreased life expectancy.
- Biliopancreatic diversion surgery is a reduction of the stomach volume and a diversion of food from the stomach to the final segment of the small intestine, bypassing the beginning and middle portions of the small intestine to limit the amount of nutrients and calories absorbed by the body. This procedure removes about one half of the stomach, and then connects the stomach to the last 250 cm of the small intestine.
- Some disadvantages of this surgery include patients suffering from protein malnutrition, anemia, gastric retention, diarrhea, abdominal bloating, and intestinal obstruction.
- gastric bypass Another bariatric surgery, “gastric bypass,” is a bypass connecting the lower compartment of the stomach to the initial portion of the small intestine. This procedure limits the amount of food that can be ingested at one sitting and reduces absorption of food across the small intestine. In addition to surgical complications, patients may also suffer from acute gastric dilation, anastomotic leak, anemia, and dumping syndrome.
- stomach gastrectomy which restricts the volume of the stomach by cutting 70-80% of the stomach using a surgical stapler.
- surgical staplers are used to cut the stomach to imitate a banana-shape.
- the stomach remnant is removed from the abdominal cavity.
- patients undergoing this procedure may suffer from reflux, life-threatening leaks, or bleeding.
- the newly formed stomach may expand over time.
- the gastric band is a band which encircles the stomach at the region of the fundus-cardia junction; it is a restrictive procedure similar to stomach stapling.
- the procedure requires general anesthesia, a pneumoperitoneum, muscle paralysis, and extensive dissection of the stomach at the region of the gastro esophageal junction.
- the procedure also requires continual adjustment of the band, or restriction of a portion of the device.
- the gastric band does not reduce the volume of the stomach by any great extent and some patients report a feeling of hunger most of the time.
- the gastric band although it is adjustable by percutaneous means, may require many iterative adjustments before it is optimally positioned.
- the port used to adjust the gastric band is left inside the patient's body.
- Embodiments disclosed herein include a gastric vest system for treating excessive weight or obesity in mammals.
- the gastric vest system may include a trapezoidal-shaped vest having a left edge and a right edge, the trapezoidal-shaped vest configured to be snugly positioned around a stomach or a modified stomach of a mammal so that the left edge is adjacent to the right edge when the trapezoidal-shaped vest is snugly positioned around the stomach or the modified stomach.

- a gastric vest system 100 including a laid-open trapezoidal-shaped gastric vest 101 having a left edge 102 , a right edge 103 , a plurality of flexible connectors 115 (e.g., three flexible connectors 115 a - c ) extending outward from one edge (e.g., left edge 102 ) of the gastric vest 101 , and a plurality of tabs 120 with openings 121 (visible in FIGS.
- the gastric vest 101 may include a top surface 108 .
- the plurality of flexible connectors 115 and the tabs 120 may be coupled to the top surface 108 .
- the trapezoidal-shaped gastric vest 101 may be configured to be snugly positioned around a stomach or a modified stomach of a mammal so that the left edge 102 is adjacent to the right edge 103 when the vest 101 is snugly positioned around the stomach or the modified stomach.
- the gastric vest 101 advantageously and uniquely has a trapezoidal shape to allow for a better (e.g., tighter and more snug) fit around the stomach or the modified stomach of a mammal (e.g., a human).
- the gastric vest 101 is made out of a silicon elastomer material infused with radiopaque material to allow the gastric vest 101 to be seen under x-ray. This advantageously allows a doctor or a technician to ensure that the gastric vest 101 is properly secured or wrapped around the stomach or the modified stomach of the mammal.
- the plurality of flexible connectors 115 and the plurality of tabs 120 can be made of the same material as the gastric vest 101 , for example, both can be made out of a silicon elastomer material infused with radiopaque material.
- the gastric vest system 100 can be made from a single mold resulting in a single material that forms the gastric vest 101 , the plurality of flexible connectors 115 and the plurality of tabs 120 .
- the plurality of connectors 115 can also be semi-flexible or semi-rigid.
- a top edge 106 and a bottom edge 107 may each extend between the left edge 102 and the right edge 103 .
- the top edge 106 may be at a top portion of the gastric vest 101 and the bottom edge 107 may be at a bottom portion of the gastric vest 101 .
- the left edge 102 and the right edge 103 may be angled towards each other, in a direction from the bottom edge 107 to the top edge 106 .
- Each of the three flexible connectors 115 a - c has a plurality of protrusions or ridges 116 (e.g., 7 ridges are shown) formed in the shape of a bucket or a cone and a cylindrical tapered end 117 .
- the flexible connectors 115 a - c may each be aligned and positioned to be perpendicular to the edge of the gastric vest 101 as shown in FIG. 1 .
- the plurality of protrusions or ridges 116 and the cylindrical tapered end 117 are only on one side or cut in half as shown in FIGS. 4 - 6 .
- the flat side 111 of the flexible connectors 115 can easily slide along the surface 108 of the gastric vest 101 and into the opening 121 of the tab 120 without snagging on the gastric vest 101 (see e.g. FIG. 4 ).
- the protrusion or ridge 116 may extend only partially around an outer surface 113 of the connector 115 (as marked in FIGS. 5 and 6 ).
- the protrusions or ridges 116 may extend in series with each other to form a longitudinal shape for the connector 115 , with the tapered end 117 at the end of the connector 115 .
- the protrusions or ridges 116 may be connected by connector portions 109 that may have a substantially constant outer surface area between the protrusions or ridges 116 .
- the series of alternating protrusions or ridges 116 and connector portions 109 may form the longitudinal shape for the connector 115 .
- the tab 120 has a maximum height of 6.75 millimeters. In one embodiment, the tab 120 may have a different height as desired. In one embodiment, the tabs 120 may be aligned and positioned to be perpendicular to the edge (e.g., right edge 103 ) of the gastric vest 101 as shown in FIG. 1 . This perpendicular alignment and positioning of the flexible connectors 115 and the tabs 120 provide for an easier connection when the gastric vest 101 is covering the stomach or the modified stomach as shown, for example, in FIGS. 9 - 11 .
- the three flexible connectors 115 a - c are formed to be part of, integrated on or to the gastric vest 101 .
- the gastric vest 101 , the plurality of protrusions or ridges 116 and the tabs 120 a - c are all molded together resulting in one piece of material to provide a stronger hold and prevent the flexible connectors 115 a - c and the tabs 120 a - c from separating or detaching from the gastric vest 101 .
- the flexible connectors 115 a - c and the tabs 120 a - c can be secured together to withstand the intragastric pressure of the stomach or the modified stomach at approximately 1.0 pound per square inch (psi).
- the top length L 1 of the top edge 106 adjacent the right or left edge ( 103 , 102 ) is 2.5 centimeters (cm)
- the bottom length L 2 of the bottom edge 107 adjacent the right or left edge ( 103 , 102 ) is 6.1 cm
- the height H or length of the right or left edge ( 103 , 102 ) is 9.9 cm. Therefore, when the gastric vest 101 covers the stomach or the modified stomach of the mammal, each flexible connector 115 a - c is pulled through each respective opening 121 a - c to allow the gastric vest 101 to be tightly secured and wrapped around the stomach or the modified stomach of the mammal.
- the dimensions provided may be varied as desired.
- the gastric vest 101 has a lower indentation 105 and an upper indentation 110 .
- the lower indentation 105 is a bottom cutout of the gastric vest 101 and has the shape of a semi-circle or is U-shaped.
- the upper indentation 110 is a top cutout of the gastric vest 101 and has the shape of a semi-circle or is U-shaped.
- the cutout of the upper indentation 110 is larger, has a greater opening and a larger surface area and goes further into the gastric vest 101 than the cutout of the lower indentation 105 .
- the larger cutout is to avoid or to go around or otherwise accommodate the gastric arteries 150 as shown in FIG. 7 .
- the indentations 105 and 110 can be any shape such as an ellipse, oval, hourglass, or perforated for a cut-out.
- each indentation 105 and 110 can be formed or cutout in the shape of a square, a triangle, an oval, a semi-circle, an ellipse, a wave, a curve, or any other shape that creates an indentation.
- the size of each indentation 105 and 110 can be varied or customized in order to provide an optimal fit around the stomach or the modified stomach.
- the indentations 105 and 110 do not necessarily have to be the same shape or size as one another.
- the lower indentation or cutout may be formed by the bottom edge 107 of the gastric vest 101 .
- the upper indentation or cutout may be formed by the top edge 106 of the gastric vest 101 .
- the bottom portion of the gastric vest 101 may include the lower indentation or cutout, and the top portion of the gastric vest 101 may include the upper indentation or cutout.
- the lower indentation or cutout may extend in a direction towards the top edge 106 of the gastric vest 101 .
- the upper indentation or cutout may extend in a direction towards the bottom edge 107 of the gastric vest 101 .
- the lower indentation 105 may be a first indentation and the upper indentation 110 may be a second indentation.

Description
- This application is a continuation of U.S. application Ser. No. 16/326,607, filed Feb. 19, 2019, now U.S. Pat. No. 11,642,235, which is a national phase entry under 35 U.S.C. 371 of International Application No. PCT/US2018/054434, filed Oct. 4, 2018, which claims the benefit and priority of U.S. Provisional Application No. 62/568,229, filed Oct. 4, 2017, the entire contents of all applications are hereby incorporated by reference.
- The invention relates to a method and an apparatus for treating obesity and controlling weight gain in mammals, and more specifically, to a gastric vest placed around a stomach or modified stomach to cause a reduced desire for eating, for treating obesity and for controlling weight gain in mammals.
- Extreme obesity is a major illness in the United States and other developed countries. More than half of Americans are overweight, while nearly one-third are categorized as obese. Obesity is the accumulation of excess fat on the body, and is defined as having a body mass index (BMI) of greater than 30. Many serious long-term health consequences are associated with obesity, such as, hypertension, diabetes, coronary artery disease, stroke, congestive heart failure, venous disease, multiple orthopedic problems, pulmonary insufficiency, sleep apnea and cancers with markedly decreased life expectancy.
- Medical management of obesity including dietary, psychotherapy, medications and behavioral modification techniques have yielded extremely poor results in terms of treating obesity. Several surgical procedures have been tried which have bypassed the absorptive surface of the small intestine or have been aimed at reducing the stomach size by either partition, removal of portions of the stomach or bypass. These procedures have been proven both hazardous to perform in morbidly obese patients and have been fraught with numerous life-threatening postoperative complications. Moreover, such operative procedures are often difficult to reverse.
- One procedure for treating morbid obesity is referred to as a “biliopancreatic diversion.” Biliopancreatic diversion surgery is a reduction of the stomach volume and a diversion of food from the stomach to the final segment of the small intestine, bypassing the beginning and middle portions of the small intestine to limit the amount of nutrients and calories absorbed by the body. This procedure removes about one half of the stomach, and then connects the stomach to the last 250 cm of the small intestine. Some disadvantages of this surgery include patients suffering from protein malnutrition, anemia, gastric retention, diarrhea, abdominal bloating, and intestinal obstruction.
- Another bariatric surgery, “gastric bypass,” is a bypass connecting the lower compartment of the stomach to the initial portion of the small intestine. This procedure limits the amount of food that can be ingested at one sitting and reduces absorption of food across the small intestine. In addition to surgical complications, patients may also suffer from acute gastric dilation, anastomotic leak, anemia, and dumping syndrome.
- Yet another bariatric surgical procedure is “sleeve gastrectomy,” which restricts the volume of the stomach by cutting 70-80% of the stomach using a surgical stapler. In this procedure, surgical staplers are used to cut the stomach to imitate a banana-shape. The stomach remnant is removed from the abdominal cavity. In addition to surgical complications, patients undergoing this procedure may suffer from reflux, life-threatening leaks, or bleeding. The newly formed stomach may expand over time.
- Minimally invasive procedures and devices which create a feeling of early satiety had been introduced into the marketplace in an attempt to address some of the issues above. The gastric band is a band which encircles the stomach at the region of the fundus-cardia junction; it is a restrictive procedure similar to stomach stapling. The procedure requires general anesthesia, a pneumoperitoneum, muscle paralysis, and extensive dissection of the stomach at the region of the gastro esophageal junction. The procedure also requires continual adjustment of the band, or restriction of a portion of the device. Although less invasive than other bariatric surgical procedures and potentially reversible, the gastric band does not reduce the volume of the stomach by any great extent and some patients report a feeling of hunger most of the time. Furthermore, once implanted, the gastric band, although it is adjustable by percutaneous means, may require many iterative adjustments before it is optimally positioned. In addition, the port used to adjust the gastric band is left inside the patient's body.
- Therefore, there is a need for minimally-invasive procedures and devices that eliminate the above-mentioned drawbacks of conventional methods and devices that are currently being used to treat obesity.
- Embodiments disclosed herein include a gastric vest system for treating excessive weight or obesity in mammals. The gastric vest system may include a trapezoidal-shaped vest having a left edge and a right edge, the trapezoidal-shaped vest configured to be snugly positioned around a stomach or a modified stomach of a mammal so that the left edge is adjacent to the right edge when the trapezoidal-shaped vest is snugly positioned around the stomach or the modified stomach. The gastric vest system may include a plurality of connectors on the trapezoidal-shaped vest. The gastric vest system may include a plurality of tabs on the trapezoidal-shaped vest, each of the plurality of tabs having an opening for insertion of a respective one of the plurality of connectors.

FIGS. 1 and 2 are views of agastric vest system 100 including a laid-open trapezoidal-shapedgastric vest 101 having aleft edge 102, aright edge 103, a plurality of flexible connectors 115 (e.g., threeflexible connectors 115 a-c) extending outward from one edge (e.g., left edge 102) of thegastric vest 101, and a plurality oftabs 120 with openings 121 (visible inFIGS. 2 and 3 ) (e.g., threetabs 120 a-c withopenings 121 a-c) on one side (e.g., right side) of thegastric vest 101 for insertion and securing to the respective threeflexible connectors 115 a-c according to an embodiment of the invention. Thegastric vest 101 may include atop surface 108. The plurality offlexible connectors 115 and thetabs 120 may be coupled to thetop surface 108. The trapezoidal-shapedgastric vest 101 may be configured to be snugly positioned around a stomach or a modified stomach of a mammal so that theleft edge 102 is adjacent to theright edge 103 when thevest 101 is snugly positioned around the stomach or the modified stomach. - The
gastric vest 101 advantageously and uniquely has a trapezoidal shape to allow for a better (e.g., tighter and more snug) fit around the stomach or the modified stomach of a mammal (e.g., a human). Thegastric vest 101 is made out of a silicon elastomer material infused with radiopaque material to allow thegastric vest 101 to be seen under x-ray. This advantageously allows a doctor or a technician to ensure that thegastric vest 101 is properly secured or wrapped around the stomach or the modified stomach of the mammal. The plurality offlexible connectors 115 and the plurality oftabs 120 can be made of the same material as thegastric vest 101, for example, both can be made out of a silicon elastomer material infused with radiopaque material. Thegastric vest system 100 can be made from a single mold resulting in a single material that forms thegastric vest 101, the plurality offlexible connectors 115 and the plurality oftabs 120. The plurality ofconnectors 115 can also be semi-flexible or semi-rigid. - A
top edge 106 and abottom edge 107 may each extend between theleft edge 102 and theright edge 103. Thetop edge 106 may be at a top portion of thegastric vest 101 and thebottom edge 107 may be at a bottom portion of thegastric vest 101. Theleft edge 102 and theright edge 103 may be angled towards each other, in a direction from thebottom edge 107 to thetop edge 106. - Each of the three
flexible connectors 115 a-c has a plurality of protrusions or ridges 116 (e.g., 7 ridges are shown) formed in the shape of a bucket or a cone and a cylindricaltapered end 117. Theflexible connectors 115 a-c may each be aligned and positioned to be perpendicular to the edge of thegastric vest 101 as shown inFIG. 1 . In one embodiment, the plurality of protrusions orridges 116 and the cylindricaltapered end 117 are only on one side or cut in half as shown inFIGS. 4-6 . This advantageously allows for a lower profile, easier insertion and a more compact design while still maintaining the secure attachment of theflexible connectors 115 a-c to thetabs 120 a-c. For example, theflat side 111 of theflexible connectors 115 can easily slide along thesurface 108 of thegastric vest 101 and into theopening 121 of thetab 120 without snagging on the gastric vest 101 (see e.g.FIG. 4 ). Thus, the protrusion orridge 116 may extend only partially around anouter surface 113 of the connector 115 (as marked inFIGS. 5 and 6 ). The protrusions orridges 116 may extend in series with each other to form a longitudinal shape for theconnector 115, with thetapered end 117 at the end of theconnector 115. Referring toFIG. 5 , the protrusions orridges 116 may be connected byconnector portions 109 that may have a substantially constant outer surface area between the protrusions orridges 116. The series of alternating protrusions orridges 116 andconnector portions 109 may form the longitudinal shape for theconnector 115. - In one embodiment, the
tab 120 has a maximum height of 6.75 millimeters. In one embodiment, thetab 120 may have a different height as desired. In one embodiment, thetabs 120 may be aligned and positioned to be perpendicular to the edge (e.g., right edge 103) of thegastric vest 101 as shown inFIG. 1 . This perpendicular alignment and positioning of theflexible connectors 115 and thetabs 120 provide for an easier connection when thegastric vest 101 is covering the stomach or the modified stomach as shown, for example, inFIGS. 9-11 . - Referring to
FIG. 1 , the threeflexible connectors 115 a-c are formed to be part of, integrated on or to thegastric vest 101. For example, thegastric vest 101, the plurality of protrusions orridges 116 and thetabs 120 a-c are all molded together resulting in one piece of material to provide a stronger hold and prevent theflexible connectors 115 a-c and thetabs 120 a-c from separating or detaching from thegastric vest 101. When connected, theflexible connectors 115 a-c and thetabs 120 a-c can be secured together to withstand the intragastric pressure of the stomach or the modified stomach at approximately 1.0 pound per square inch (psi). - In one embodiment, as an example, the top length L1 of the
top edge 106 adjacent the right or left edge (103, 102) is 2.5 centimeters (cm), the bottom length L2 of thebottom edge 107 adjacent the right or left edge (103, 102) is 6.1 cm, and the height H or length of the right or left edge (103, 102) is 9.9 cm. Therefore, when thegastric vest 101 covers the stomach or the modified stomach of the mammal, eachflexible connector 115 a-c is pulled through eachrespective opening 121 a-c to allow thegastric vest 101 to be tightly secured and wrapped around the stomach or the modified stomach of the mammal. In embodiment, the dimensions provided may be varied as desired. - The
gastric vest 101 has alower indentation 105 and anupper indentation 110. Thelower indentation 105 is a bottom cutout of thegastric vest 101 and has the shape of a semi-circle or is U-shaped. Similarly, theupper indentation 110 is a top cutout of thegastric vest 101 and has the shape of a semi-circle or is U-shaped. The cutout of theupper indentation 110 is larger, has a greater opening and a larger surface area and goes further into thegastric vest 101 than the cutout of thelower indentation 105. The larger cutout is to avoid or to go around or otherwise accommodate thegastric arteries 150 as shown inFIG. 7 . Theindentations indentation indentation indentations - The lower indentation or cutout may be formed by the
bottom edge 107 of thegastric vest 101. The upper indentation or cutout may be formed by thetop edge 106 of thegastric vest 101. The bottom portion of thegastric vest 101 may include the lower indentation or cutout, and the top portion of thegastric vest 101 may include the upper indentation or cutout. The lower indentation or cutout may extend in a direction towards thetop edge 106 of thegastric vest 101. The upper indentation or cutout may extend in a direction towards thebottom edge 107 of thegastric vest 101. In one embodiment, thelower indentation 105 may be a first indentation and theupper indentation 110 may be a second indentation. The bottom cutout may be a first cutout and the top cutout may be a second cutout. -
FIG. 3 is a cross-sectional view of atab 120 ofFIG. 1 along line I-I inFIG. 1 according to an embodiment of the invention. The cross-sectional view of thetab 120 may be of any of thetabs 120 a, b, c. The cross-sectional area of theopening 121 of thetab 120 is sized to be smaller than the cross-sectional area of the protrusion orridge 116, which may be semi-circular, round, tapered, square, triangular, trapezoidal or other configurations in shape, so that thetab 120 can securely hold the protrusion orridge 116 in place in a relatively fixed position. That is, the flat portion 114 (marked inFIG. 5 ) of the protrusion orridge 116 extends beyond theopening 121 so that it rests against a contact portion in the form of asurface 122 a of thetab 120 so it is difficult to pull theflexible connector 115 back through theopening 121 once inserted through theopening 121. The cross-sectional area of the protrusion orridge 116 is larger than the cross-sectional area of theopening 121 of thetab 120. A contact portion in the form of asurface 122 b may be positioned within acavity 124 of thetab 120.
