Abstract
The utility model discloses an intravascular stent comprising a medicine carrying structure. The intravascular stent comprises an intravascular stent main body which comprises a vertical strip layer and a horizontal strip layer; the vertical strip layer and the horizontal strip layer are in a woven structure shape; the horizontal strip layer comprises a film covering layer and a medicine carrying tube; the outer side of the medicine carrying tube is provided with the film covering layer. According to the intravascular stent comprising the medicine carrying structure, the medicine carrying structure is adopted and accordingly a lesion and occlusion blood vessel can be supported when the intravascular stent is placed into the blood vessel and meanwhile a medicine layer is attached and accordingly the blood circulation flow can be prompted.
Description
Technical field
This utility model relates to field of medical products, particularly relates to a kind of intravascular stent with medicine carrying structure.
Background technology
Intravascular stent refers to narrow, the inaccessible blood vessel for support human body endogenous cause of ill pathological changes, recovers the tubular device of blood circulation.Intravascular stent conventionally adopts metal or macromolecular material etc. to have some strength and flexible materials processing is made, and can stay in human vas for a long time or temporarily.Intravascular stent is on the basis being shaped at tube chamber balloon expandable, inserts inner support support stenosis occlusion section blood vessel to reach in pathological changes section, reduces blood vessel elasticity retraction and moulding again, keeps the unobstructed object of tube chamber blood flow.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of intravascular stent with medicine carrying structure, adopts medicine carrying structure, when intravascular stent is inserted in blood vessel, can support the blood vessel of pathological changes, obturation, simultaneously with medicine layer, can flow by blood circulation promoting.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of intravascular stent with medicine carrying structure is provided, comprise: intravascular stent main body, described intravascular stent main body comprises vertical bar layer and horizontal stripe layer, described vertical bar layer and horizontal stripe layer are braiding structure shape, described horizontal stripe layer comprises coating layer and medicine carrying pipe, and the outside of described medicine carrying pipe is provided with coating layer.
In preferred embodiment of this utility model, described medicine carrying pipe inside is provided with medicine layer.
In preferred embodiment of this utility model, described medicine layer is flunarizine.
In preferred embodiment of this utility model, the diameter of described medicine carrying pipe is 0.05-0.07mm.
In preferred embodiment of this utility model, the surface of described vertical bar layer is provided with through hole.
The beneficial effects of the utility model are: adopt medicine carrying structure, when intravascular stent is inserted in blood vessel, can support the blood vessel of pathological changes, obturation, simultaneously with medicine layer, can flow by blood circulation promoting.

Detailed description of the invention
To the technical scheme in this utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of this utility model protection.
This utility model embodiment comprises:
A kind of intravascular stent with medicine carrying structure, comprise: intravascular stent main body, described intravascular stent main body comprises vertical bar layer 1 and horizontal stripe layer 2, described vertical bar layer 1 and horizontal stripe layer 2 are braiding structure shape, described horizontal stripe layer 2 comprises coating layer 3 and medicine carrying pipe 4, the outside of described medicine carrying pipe 4 is provided with coating layer 3, and the diameter of described medicine carrying pipe 4 is 0.05-0.07mm.
In addition, described medicine carrying pipe 4 inside are provided with medicine layer 5, and described medicine layer 4 is flunarizine, and energy blood circulation promoting, treats some cardiovascular and cerebrovascular diseases.
In addition, the surface of described vertical bar layer 1 is provided with through hole, can accelerate drug diffusion, and blood circulation promoting flows.
The beneficial effect of a kind of intravascular stent with medicine carrying structure of this utility model is:
Adopt medicine carrying structure, when intravascular stent is inserted in blood vessel, can support the blood vessel of pathological changes, obturation, simultaneously with medicine layer, can flow by blood circulation promoting.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
