Specific embodiment
The core of the present invention is to provide a kind of intravascular stent, simplifies operative process, improves success rate of operation, has dropped hand
Art expense.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Fig. 1 is refer to, Fig. 1 is a kind of structural representation of specific embodiment of intravascular stent provided by the present invention.
The intravascular stent that the specific embodiment of the invention is provided, including elastic hollow out spheroid 1, set on elastic hollow out spheroid 1
Hollow hole is equipped with, elastic hollow out spheroid 1 can be elongated to move by compression in intravascular, and elastic hollow out spheroid 1 can be in blood
Spheroid is launched in pipe, makes to be adjacent to outside elastic hollow out spheroid 1 and be fixed on blood vessel.Specifically, according to operated vessels
Internal diameter, a diameter of 1 millimeter to 10 millimeters when elastic hollow out spheroid 1 launches.
During operation, elastic hollow out spheroid 1 is elongated by compression first, can be moved in intravascular, when being moved to predeterminated position,
Elastic hollow out spheroid 1 is launched into spheroid, is adjacent to internal blood vessel so as to be fixed on predeterminated position outside which, to carry out subsequent operation.
No matter placed with which kind of orientation, be all presented uniform spherical after expansion, so can discharge without the need for deliberately positioning, facilitate operation
Operation, and the success rate of operation is improve, reduce surgery cost.Also can receive in intravascular in incomplete release conditions simultaneously
The constraint ovalize or other random geometries of vascular wall, grabs wall good.
Elastic hollow out spheroid 1 can have various processing modes, can be woven into spheroid by netted by memory wire,
As memory metal mesh-like woven ball body.Mesh is hollow hole, and mesh form can be regular or irregular polygon,
Polygon is evenly distributed, also can uneven arrangement.Specifically, nitinol alloy wire can be adopted, other materials may also be employed, at this
Within the protection domain of invention.
Certainly elasticity hollow out spheroid 1 can also be arranged for integral type, and hollow hole is specially laser cut hole, will hollow ball
Body goes out hollow hole by laser cutting.
On the basis of the intravascular stent that above-mentioned each specific embodiment is provided, for the ease of operation, can also engrave in elasticity
Development indicating 2 is installed on empty spheroid 1.Developing mark 2 can be also not provided with, be directly arranged in developing material in nitinol alloy wire again
Core.
Development indicating 2 can be the development wire for being wound in elastic hollow out spheroid 1, such as platinum, platinum alloy, tungsten, Jin He
Gold etc. are material, are developed wiry a diameter of 0.01 millimeter to 0.05 millimeter.Also development indicating 2 can be welded in elastic hollow out
Spheroid 1.Specifically, four development indicatings 2 can be set.According to circumstances the quantity and set-up mode of adjustment development indicating 2, exists
Within protection scope of the present invention.
Occupation mode of the intravascular stent in the specific embodiment of the invention introduced below in different operations, refer to figure
2, Fig. 2 is that intravascular stent provided by the present invention is used for a kind of aneurysmal schematic diagram of specific embodiment of base soil stress.
At base soil stress 5 or other vascular bifurcations, there is aneurysm 4, elastic hollow out spheroid 1 is put by microtubular 6
Base soil stress 5 is placed in, now elastic hollow out spheroid 1 launches and be bifurcated position and block not being shifted over.Due to elastic hollow out
Spheroid 1 is in spherical, and the shape at arbitrary position is consistent, no matter is placed with which kind of orientation, and elastic hollow out spheroid 1 is all presented after flicking
It is uniform spherical, so can discharge without the need for deliberately positioning.After elastic hollow out spheroid 1 is in place, you can by another
Microtubular fills turn 3 into aneurysm 4.The microtubular that turn 3 can also first be conveyed is sent to position, then discharges elastic hollow out
Spheroid 2.
Refer to Fig. 3 and Fig. 4, Fig. 3 is that intravascular stent provided by the present invention is embodied as one kind of vascular occlusion
The schematic diagram of mode；Fig. 4 is showing for another kind of specific embodiment that intravascular stent provided by the present invention is used for vascular occlusion
It is intended to.
As shown in figure 3, elastic hollow out spheroid 1 is released in expected position first, comply with as elastic hollow out spheroid 1 has
Property, now elastic hollow out spheroid 1 is adjacent to vascular wall, is fixed in blood vessel 7 by vascular wall.Turn 8 is released in into elastic hollow out
In the blood vessel 7 of 1 near-end of spheroid, turn 8 is rushed at 7 distal end of blood vessel by blood flow, and wherein blood flow direction is, by proximate, to work as bullet
When spring coil 8 encounters elastic hollow out spheroid 1, it is fixed in blood vessel 7 by elastic hollow out spheroid 1 and forms embolism.Also can as shown in figure 4,
Turn 8 is released in inside elastic hollow out spheroid 1, turn 8 is wrapped up and is fixed in blood vessel 7 by elastic hollow out spheroid 1, from
And form embolism.Other operations are can be naturally also applied to, within protection scope of the present invention.
Above intravascular stent provided by the present invention is described in detail.Specific case used herein is to this
Bright principle and embodiment are set forth, the explanation of above example be only intended to help understand the method for the present invention and its
Core concept.It should be pointed out that for those skilled in the art, in the premise without departing from the principle of the invention
Under, some improvement and modification can also be carried out to the present invention, these improve and modification also falls into the protection of the claims in the present invention
In the range of.
