Description
Technical field
The utility model belongs to medical instruments field, and in particular to for the aneurysmal blood with side opening of cerebral artery crotch
Pipe holder.
Background technology
Aneurysm is due to ductus arteriosus wall local weak and a kind of permanent expansion disease for occurring.Cerebral aneurysm belongs to
Peripheral aneurysm, refers to knurl sample projection caused by the expansion of cerebral artery tube wall limitation, the aneurysm knurl wall of projection in blood flow not
The disconnected lower gradual thinning and final Rupture haemorrhag of impact.Ruptured intracranial aneurysm morbidity urgency, severe symptoms, without obvious tendency, have
The very high death rate and disability rate.Mainly a point surgical clamp is closed and endovascular intervention treatment for the treatment of cerebral aneurysm.But
Surgical clamp close wound is big, complication is more, operation and recovery time it is all very long, do not welcome by doctor and patient.With
The progress of the intravascular Interventional Treatment technology of minimal invasive, increasing cerebral aneurysms receive intravascular Interventional Treatment
Technology, endovascular intervention technology are increasingly becoming the dominant technology of cerebral aneurysm treatment.
The Treatment of Endovascular Embolization of cerebral aneurysm, mainly it is implanted into using detachable coil by microtubular in aneurysm
Carry out embolism so that form thrombus in aneurysm cavity and close and reach dissection healing.For the wide neck at aortic bifurcation
For aneurysm, simple turn is not easy embolism, generally requires support auxiliary embolism；At this moment, it is necessary to be respectively implanted two branch
In two Main Branches of frame intravasation, Coil embolization treatment could be carried out.Share three steps：The first step, insert first
Support；Second step, intersection insert second support；3rd step, microtubular is put into artery by intersecting two supports inserted
Coil embolization is carried out in knurl.Such step operation is comparatively laborious, and support is also wide to the coverage of blood vessel, may cause not
It is necessary branch vessel tube wall hyperplasia, narrow or even inaccessible；When inserting operation, complicated operation may also trigger thrombus shape
Into causing unnecessary embolic complications.In addition, if only be implanted into a support, can not close well again aneurysm oral area,
Carry out safe treatment.Chinese patent ZL201520538028.0 and ZL201520538205.5 are disclosed for treating cerebral artery point
The treatment principle of aneurysmal intravascular stent and top overlay film frame at fork, but the net bar of rack far end both sides is to entering branch's blood
The blood flow of pipe plays certain barrier effect, is unfavorable for blood and smoothly enters branch, and is easy to the net bar for causing component inlet
Upper formation thrombus.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for treating the aneurysmal band of cerebral artery crotch
The intravascular stent of side opening, it is easy to place and treats crotch aneurysm, is advantageous to blood and smoothly enters branch vessel, eliminate support
Net bar reduces the risk that thrombus is formed on net bar, improves the security for the treatment of to the barrier effect of blood.
The technical solution of the utility model：
It is a kind of to be used to treat the aneurysmal intravascular stent with side opening of cerebral artery crotch, including：Rack body, the branch
Frame body is tubular network structure, and the rack body is included proximally and distally, and the near-end opens, and is distally tied for closure
Structure, the rack body both sides of the close distal end respectively set one and are easy to the side opening that blood passes through.
Further, the distal end is the netted enclosed construction that net bar is formed.
Further, the sizing grid that the net bar is formed is 1 millimeter -3 millimeters.
Further, the distal end is overlay film closing structure, and overlay film is provided centrally with overlay film centre bore.
Further, the overlay film is biocompatible membrane.
Further, the biocompatible membrane is poly tetrafluoroethylene.
Further, the distal end is the enclosed construction that net bar and overlay film collectively constitute, and the net bar is located at the upper of overlay film
End or lower end.
Further, it is described to be proximally and distally respectively arranged with metal marker thing.
Further, the distal end is expanded outwardly in enlarging shape.
Further, the rack body is eject or the swollen formula of ball.
It is titanium silk, tungsten filament, NiTi to be used for stent body of the aneurysm with side opening at vascular bifurcation in the utility model
B alloy wire, tantalum wire, stainless steel wire, golden alloy wire any one or two kinds of compositions composite.Also absorbable material may be selected
Or medical material, such as：Makrolon, polyanhydride copolymer, gel or magnesium alloy.
The utility model intravascular stent is used cooperatively with guiding wire, conveying microtubular, conveying lever, guiding catheter, is
Well known to a person skilled in the art prior art.
Stent body of the present utility model has a shrinkage, and profile is mesh cylinder shape under release conditions, with artery
Cerebral artery vessel inwall at knurl is adapted, and is shunk and is fixed in microtubular under feed status, and under the guiding of guiding wire
It is delivered at the aneurysm of aortic bifurcation, is discharged for treating aneurysm through guiding catheter.
Good effect of the present utility model：
（1）Rack body is adapted with arteries inwall, can distally be expanded outwardly in enlarging shape, is increased in crotch
To the adhesive force of blood vessel, prevent support from coming off, and block aneurysmal oral area well.
（2）Rack far end is that netted closing structure can directly be closed in aneurysm oral area, and this is better than intersection two branch of implantation
Frame treats furcation cerebral aneurysm, makes Coil embolization treatment easier.If rack far end is membranaceous closing structure, can
Aneurysm oral area is directly closed, without being implanted into turn, more simplifies step.
（3）Respectively there is a side opening rack far end both sides, be easy to blood flow by, eliminate the barrier effect of support net bar,
Reduce net bar and cause thrombotic risk.
（4）Near-end opens so that blood can enter far-end branch blood vessel normal through support.
（5）Proximally and distally the metal marker thing of closing structure is easy to positioning to place site, when discharging support, allows support
The radiopaque metal marker thing of distal end is located at aneurysm oral area at aortic bifurcation, fixed support conveying lever, gradually withdraws micro- lead
Pipe, support can be to be released to appropriate location.Power supply is now connected, is taken off using electrolysis and conveying lever is freed from support and withdrawn from defeated
Send bar.
