Definitions
- This invention relates to a device for capturing and removing bodies or articles from within a vessel, such as those of the cardiovascular system or the genitourinary tract.
- Embolization of vessels is becoming of increasing therapeutic importance in treating conditions such as arteriovascular malformations, aneurysms, fistulas, vascular tumors, and the like.
- the procedure involves placing foreign bodies such as metal coils, balloons, beads, and the like into the vessel. At times these bodies become errant or it is desired to retrieve and remove them from the vessel for other reasons.
- Existing snares are too stiff and/or too large to permit deep tissue access through tortuous vessel paths.
- the present invention provides a device for retrieving bodies or articles from either tortuous vascular structures or larger vessels, organs, or ducts.
- the distal structure of the device of the present invention can act to some degree like a guidewire, thus enabling the device to be somewhat guidewire directed.
- existing snare devices cannot be directed like a guidewire.
- a first elongated member having a proximal end, a distal end, and a lumen extending therebetween, said first elongated member being capable of being advanced through the vessel to the site of the body;
- a second elongated member having a proximal end and a flexible distal end that is received through the lumen with the distal end of the second elongated member extending distally of the lumen and being looped back and affixed to the distal end of the first elongated member to form a loop whose size may be adjusted by axial movement of the second elongated member.
- Fig. 1 is a fragmentary, partly sectional view of the device of the invention.
- Fig. 2 is an enlarged sectional view of the distal end of the device of claim 1.
- Figs. 3A-3D are enlarged sectional partial views of the device of Figure 1 depicting the operation of the device.
- Figures 1 and 2 depict a preferred embodiment of the retrieval device of the invention.
- the retrieval device as a whole is generally designated 10. Its principal components are: a proximal end fitting 11; a catheter tube 12; and a flexible wire 13 that extends axially through the fitting and catheter tube.
- Fitting 11 has a conventional structure that is commonly used at the proximal end of a catheter. It has a main body and an integral side arm 15.
- the main body 14 has a central axial lumen through which the flexible wire 13 is received.
- the side arm has a lumen which connects into the lumen of the main body.
- the proximal end of the side arm is connected to a source (not shown) of a physiologically acceptable fluid.
- the source preferably provides the fluid under pressure.
- the fluid will be introduced into the side arm via a syringe or a tube connected to a pressurized intravenous fluid bag (not shown) connected thereto.
- catheter 12 The proximal end 16 of catheter 12 is connected to the distal end of fitting 11 with the lumen 17 of the catheter communicating with the lumen of main body 14.
- the structure and size of catheter 12 is such as to permit it to be inserted within the small vessels of the peripheral vascular system.
- the catheter is of the structure and size described in U.S. Patent No. 4,955,862, the disclosure of which is incorporated herein by reference.
- Wire 13 extends axially through the entire length of catheter and extends out of the distal end 18 (see Fig. 2) of the catheter.
- the structure and dimensions of wire 13 are similar to those of a conventional guidewire.
- Preferably wire 13 has the structure and dimensions of the guidewire described in U.S. Patent No. 4,884,579, the disclosure of which is incorporated herein by reference.
- the distal end 19 of the wire is wrapped with a wire coil 20.
- the coil may be made of any conventional medically acceptable metal such as stainless steel, tungsten, platinum, platinum alloys, gold and gold alloys.
- the use of a radiopaque metal makes the end visible radiographically.
- Coil 20 serves to protect the distal end 19 from kinking when it is manipulated.
- the distal tip 22 of the wire is affixed to the exterior of the distal end of the catheter by means of a tightly wrapped metal coil 23 or metal band that extends around the circumference of the tip of the catheter. It may also be affixed to the interior wall of the catheter provided the lumen is large enough to permit same, or it may be affixed to coil 23 by solder and/or to the catheter wall by fusion with the plastic forming the catheter.
- Coil 23 is preferably made of a radiopaque metal such as platinum so that the location of the end of the catheter is visible radiographically.
- a separate radiopaque band or coil may be affixed to the tip of the catheter.
- the affixation of the tip of wire 13 to the catheter forms the distal end of the wire into a loop 24, the size of which may be altered by axial movement (represented by the double-headed arrow in Figs. 1 and 2) of wire 13.
- the extended configuration of loop 24 is shown in solid and dashed lines in Fig. 2 and the retracted configuration of loop 24 is shown in phantom lines in Figure 2.
- Figures 1 and 3A-D show how the retrieval device is used to retrieve a body from within a vessel.
- the device is inserted into a vessel 25 so that the distal end of the device is adjacent to the body to be removed from the vessel -- in the depicted case a vasoocclusive coil 26.
- the insertion of the device to such a location is accomplished in a conventional manner. Insertion can be facilitated by alternately advancing and withdrawing the loop -- i.e., using the loop as a guidewire.
- a larger catheter 27 may be placed in the vessel using a separate guidewire (not shown) and the catheter-wire assembly of the invention inserted to the site via catheter 27.
- loop 24 of the device is enlarged by distal advancement of wire 13 while holding catheter 12 stationary.
- a physiologically acceptable fluid represented by arrows 28 in Figures 3A-3D
- Loop 24 is manipulated within the vessel to ensnare (see Fig. 3B) coil 26. Once the coil is ensnared, the loop 24 is retracted (see Fig. 3C) by proximal movement of wire 13 so that the coil 26 is held firmly by the loop against the tip of the catheter. The thus captured and firmly-held coil 26 is removed from the vessel by withdrawing the catheter-wire assembly from the vessel (see Figure 3D) or into catheter 27.
