The invention provides a kind of cerebrovascular fake formula falsework 101, and narrow dilation therapy is blocked for the cerebrovascular.
As shown in figure 1, An embodiment provides a kind of cerebrovascular fake formula falsework 101, including gold
Category rack body 1 and the suture 2 for being fixed on the edge part 11 of metallic stent body 1, are illustrated one by one below according to Fig. 1.
The structure of metallic stent body 1 can be the metallic support of this area any shape, preferably netted cylinder, adopt
Formed with the braiding of single nitinol alloy wire, hollow channel of blood flow is provided for support blood vessels wall and for blood flow.Metallic support sheet
There is mesh on body 1, its is flexible to carry out free shrink, can be compressed into line style under stress, nature (i.e. without
Under active force) under can be cylindrical, its shape can be adjusted according to the shape of blood vessel of its position.Nitinol has good
Good super-elasticity, stable tension force can be kept, can be brought into close contact using metallic support made of Nitinol with vessel lumen wall,
With good biocompatibility, corrosion resistance and pliability；It is easy to operate and metallic support is easily incorporated supplying system.
In order to meet the adherence quality of the structure of metallic stent body 1 and prevent the generation of cerebral hyperpefusion syndrome, by gold
Category rack body 1 is designed as the structure for including cylindrical support portion and coupled blood flow control unit；Wherein, cylindrical support portion
For hollow tubular network structure, hollow channel of blood flow, generally, metallic support sheet are provided for support blood vessels wall and for blood flow
The diameter in the cylindrical support portion of body 1 is preferably 0.5-6mm.Blood flow control unit is also hollow network structure, and cylinder is come from for slowing down
The speed of the blood flow of shape supporting part simultaneously provides hollow channel of blood flow for blood flow, and the cross-sectional area of blood flow control unit is less than tubular branch
The cross-sectional area of support part, such structure can both ensure that there is metallic stent body 1 good adherence quality and can to prevent brain mistake
The generation of degree perfusion syndrome.
In addition, in order to further prevent the generation of cerebral hyperpefusion syndrome, the cross-sectional area of blood flow control unit is along near
Hold and be first gradually reduced to the direction of distal end and then become larger again；Preferably, blood flow control unit is axially symmetric structure；More preferably
Ground, cylindrical support portion are N number of, and blood flow control unit is N-1, and N is not less than 2, and each blood flow control unit is proximally and distally distinguished
Connect tubular supporting part.Metallic stent body 1 is designed as into said structure can not only increase support and patient's diseased region blood vessel
Adherence quality, reduce the stimulation to vascular wall and constriction, improve adaptability of the patient for additional intravascular stent, moreover it is possible to be more preferable
Ground prevents the generation of cerebral hyperpefusion syndrome.
Because scraggly phenomenon occurs in the blood vessel for producing pathological change of thrombus position unavoidably, therefore, metallic stent body 1
The design of structure is mainly for improving its adherence quality and the effect to the effective support of blood vessel, so that patient's rehabilitation as early as possible, in addition also
The comfort of patient need to be considered, reduce stimulation and constriction of the support to vascular wall, improve adaptability of the patient to support.
In order to improve the adaptability of patient and comfort level, suture 2 elects medical non-degradable suture 2 as；Suture 2 can
Preferably metal wire, cotton thread, polyester or polypropylene etc., it is highly preferred that suture 2 is polypropylene, polyamide or cellulose etc..For
Suture 2 is fixed on the edge part 11 of metallic stent body 1 more securely, will seam by the way of fasten or link
The edge part 11 that zygonema 2 is fixed on metallic stent body 1 is all provided with the edge part 11 proximally and distally of metallic stent body 1
Suture 2 is put.
The edge part 11 of metallic stent body 1 is preferably arranged to round and smooth edge part 11, can reduce it and vascular wall is pierced
Swash.Further, it is follow-up for convenience to take out metallic stent body 1, along the circumferencial direction of metallic stent body 1 by suture 2
Sequentially through the edge part 11 of metallic stent body 1 mesh to form closed loop fake, and form tubercle and suture 2 knot fixation
In (as shown in Figure 3) on metallic stent body 1.That is, the circumference of edge part 11 of the suture 2 along metallic stent body 1
It is fixed, the edge part of metallic stent body 1 is tightened up when being easy to pull suture 2, is led so that metallic stent body 1 closes at recovery
The operation of pipe is simpler, easy.
Further, taken out for the ease of cerebrovascular fake formula falsework 101, it is preferably near in metallic stent body 1
The edge part 11 at end sets suture 2 (as shown in Figure 2).
The specific conveying of the cerebrovascular fake formula falsework 101 and recovery method are as follows：It will be managed along guiding wire
The delivery conduit for inside accommodating the cerebrovascular fake formula falsework 101 is delivered to ad-hoc location, available in course of conveying
Developing mark on metallic stent body 1 determines delivery conduit position, after delivery conduit has arrived ad-hoc location, will convey
Conduit is withdrawn so that cerebrovascular fake formula falsework 101 is opened, treat falsework be on active service after the completion of i.e. vascular lesion position
After healing is good, cerebrovascular fake formula falsework 101 is reclaimed using recovery system of the front end with round and smooth hook-shaped apparatus, it is hook-shaped
Apparatus catches on suture 2 and tensed, and after the proximal retraction of falsework is complete, successively goes back to the near-end of falsework, distal end
Receive to conduit is reclaimed, then falsework is withdrawn from vitro with recovery conduit.Again will by the way that falsework near-end is first shunk
It takes in recovery conduit, reduces falsework and enters the stimulation brought during recovery conduit to vascular wall, namely reduces
The pain and sense of discomfort of patient.Hook-shaped apparatus used meets medical requirement, and recovery conduit used is of the prior art
The recovery conduit of intravascular stent.
On the one hand the cerebrovascular fake formula falsework 101 of the present invention is made it easier to from intravascular by setting suture 2
Take out, reduce the pain and sense of discomfort taken out and brought during falsework to patient；On the other hand falsework can also be suppressed to exist
Endovascular drift, the speed of vascular lesion position rehabilitation is improved, can also efficiently avoid blood vessel thrombus and narrow again
Risk；And suture 2 is set not bring sense of discomfort and constriction to patient.
In use, in order to improve the accuracy of positioning, several developing marks are provided with metallic stent body 1
(not shown), developing mark is set to be accurately positioned the position of metallic support in the blood vessel, person easy to operation enters to support
Row operation and monitoring.For example two developing marks are symmetrical arranged in the distal peripheral edge of metallic stent body 1, in metallic stent body
1 near-end periphery is symmetrical arranged two developing marks, i.e., both sides respectively set two developing marks end to end, and the material of developing mark is
The Radiopaque markers such as gold, platinum, tungsten or iridium.In order to more effectively improve the positioning accuracy of patient, by radiopaque mark
Thing is arranged on tubular structure on the twine of metallic stent body 1, for example Radiopaque marker is made into metal pipe sleeve in gold
On the twine for belonging to rack body 1；Or the wire of Radiopaque marker is wrapped on the twine of metallic stent body 1；Or
The metal dust of Radiopaque marker is arranged on the twine of metallic stent body 1 i.e. in metallic support using spraying plating mode
The coating of Radiopaque marker is formed on the twine of body 1.
