Abstract
The invention discloses a biforked stent with a membrane, which consists of a stent backbone and two stent branches. The stent backbone is respectively communicated with the two stent branches; the whole stent with the membrane has a 'Y'-shaped structure; and the front end of the stent with the membrane is biforked. Compared with the prior art, the biforked stent with the membrane has the advantages that the stent and a vessel are stably embedded under the situation of not obviously influencing the running of blood stream, thereby effectively sealing the inner port of a hemangioma; meanwhile, as the stent is combined with the vessel on three directions, the stent is hard to fall off, thus greatly improving the safety; and the stent completely protects the part of the biforked position of the vessel directly impacted by the blood stream, thereby effectively reinforcing the inner wall of the vessel.
Description
Technical field:
The invention belongs to medical instruments field, relate to a kind of band film vascular bifurcation support (Y shape support) device, intervention device in particularly a kind of blood vessel of the hemangioma shutoff that is used to carry out the vascular bifurcation place.
Background technology:
At present, in the hemangioma interventional therapy method, realize that by importing band film intravascular stent the technology of hemangioma shutoff is ripe day by day.But, or else influence and realize getting involved shutoff under the prerequisite of blood flow operation or filling then has very big difficulty for the hemangioma at vascular bifurcation place.Usually the method for taking is to close hemangioma with vascular clamp folder under the operation direct-view, or gets involved the filling hemangioma in blood vessel with filamentary silver.Because the vascular bifurcation position is subjected to blood flow impact force bigger, blood vessel wall is damaged easily, hemangioma incidence rate height, and recurrence easily.
Summary of the invention:
The objective of the invention is to overcome existing band film intravascular stent and be difficult to sealing and be present in the angiomatous shortcoming in vascular bifurcation place, the device of getting involved shutoff hemangioma (vascular bifurcation place hemangioma) in a kind of novel blood vessel is provided.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
But a kind of band film intravascular stent of bifurcated, described band film intravascular stent is made of support trunk and two support branches, and this support trunk is communicated with two support branches respectively; Described band film intravascular stent integral body is " Y " type structure, its front end bifurcated.
Be provided with two seal wires in the described band film intravascular stent, two seal wires insert the support trunk simultaneously, and then enter two support branches respectively.
Described band film intravascular stent has axial pliability, is to make by combining artificial membrane with the tissue compatibility material.
Band film vascular bifurcation support of the present invention (Y shape support) device, integral body is " Y " shape, and its front end bifurcated can separate flexibly, is specially for the hemangioma design at shutoff vascular bifurcation position.This kind endovascular stent is guided by two seal wires, can open " Y " shape bifurcated of its front end naturally at the purpose vessel segment, the stable aneurysm site that is embedded in the vascular bifurcation place, the opening of sealing aneurysm on blood vessel.
In the such scheme, described intravascular stent must be by two guide wire guidings, and after two guide wire were in place, the zipper pull of support just as sliding on the clothes slide fastener slid against on two seal wires, and the leading portion bifurcated naturally separately after arriving the purpose position; The back is chimeric with blood vessel strutting fully.Described intravascular stent is " Y " shape, and its front end is forked to be separated.It can be aided with artificial membrane by tissue compatible material and make.
Compared with prior art, advantage of the present invention is that support and blood vessel are stablized chimeric, the internal orifice of effective sealing blood vessels tumor under the not obvious situation that influences blood flow operation; And support is owing to combine with blood vessel on 3 directions, so more be difficult to come off, safety greatly improves; Support has protected the vascular bifurcation place to be subjected to the direct ballistic position of blood flow fully, has effectively reinforced blood vessel.
Description of drawings
But Fig. 1 is the band film intravascular stent state diagram of bifurcated of the present invention;
Fig. 2 is the present invention's unfolded ideograph of beginning under the guide wire traction;
Fig. 3 for the present invention when arriving the purpose position, the ideograph that " Y " shape head end is opened fully;
Fig. 4 is that ideograph is seen in the side of support action effect the present invention struts support under dilator helps after.
Wherein: 1 is that support trunk, 2 is that support branch, 3 is seal wire.
The specific embodiment
The present invention is described in further detail below in conjunction with using step explanation accompanying drawing.
As Fig. 1, Fig. 2 of operation instruction accompanying drawing part, shown in Figure 3, but a kind of band film intravascular stent of bifurcated, described band film intravascular stent is made of support trunk and two support branches, and this support trunk is communicated with two support branches respectively; Described band film intravascular stent integral body is " Y " type structure, its front end bifurcated.
Be provided with two seal wires in the described band film intravascular stent, two seal wires insert the support trunk simultaneously, and then enter two support branches respectively.Described band film intravascular stent has axial pliability, is to make by combining artificial membrane with the tissue compatibility material.
Be somebody's turn to do " Y " shape endovascular stent under two guide wire guiding, slowly open, after arriving the purpose position, open fully by the draw of guide wire; Under the help of distraction instrument support is strutted then, make support and vascular bifurcation closely chimeric, the membrane structure on the support can be with hemangioma in the complete shutoff of the opening of vascular inner surface.And this support can not influence the normal operation of blood flow, and has further reinforced the vascular bifurcation position, makes this position resist the ballistic ability of blood flow and obviously improves.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
