Abstract
The invention provides a novel cardiovascular stent. The novel cardiovascular stent is characterized by comprising a stent body, a membrane layer, a biodegradation layer, a drug layer, and a protection layer. The outer side of the stent body is coated with the protection layer; the outer side of the protection layer is coated with the drug layer; the drug layer at the inner side of the stent body is coated with the biodegradation layer; and the membrane layer is arranged at the outer side of the drug layer at the outer side of the stent body. The membrane layer is a collagen membrane; when the collagen is attached to the stent body, lesion and the blood flow can be isolated fully and the collagen can bond with and collect with blood platelets to play a role in stopping bleeding; on the basis of the three-screw structure, blood platelet attachment can be induced to generate a releasing reaction; and the blood coagulation factor can be activated to adhere to the bleeding wound, so that the damaged blood vessel can be filled well. The stent body has a meshed structure, so that the stent can be expanded conveniently.
Description
Technical field
The present invention relates to medical field, more particularly to a kind of Novel cardiovascular support.
Background technology
With the development of science and technology, the progress of medical skill, numerous disease can be treated, and extend the life-span of patient.Angiocarpy bracket is to treat a kind of instrument of cardiovascular disease, intravascular stent is referred on the basis of the shaping of tube chamber balloon expandable, inner support is inserted in lesion and support stenosis occlusion section blood vessel to reach, reduce blood vessel elasticity retraction and moulding again, the purpose for keeping tube chamber blood flow unobstructed.Angiocarpy bracket simple structure now, service life is short, and can not be extended, and when patient extends because of sick cardiovascular, angiocarpy bracket can produce obstruction to it, extremely affect the health of patient.
The content of the invention
According to above technical problem, the present invention provides a kind of Novel cardiovascular support, it is characterised in that including rack body, coating layer, biodegradation layer, medicine layer,
Protective layer, the rack body outside parcel matcoveredn, the protective layer outside is enclosed with medicine layer, and the medicine layer on the inside of the rack body is enclosed with biodegradation layer, and the medicine layer outside on the outside of the rack body is coating layer.
The rack body is network.
The rack body is expandable structure.
The biodegradation layer degradable macromolecule grafted branch heparin.
The coating layer is collagen film.
Beneficial effects of the present invention are：The coating layer of the present invention is collagen film, collagen protein is attached on rack body, pathological changes and blood flow can not only be adequately isolated, collagen protein can also cohere with platelet, assemble and play a part of hemostasis, its triple-helix structure can induced platelet attachment, produce release reaction, and blooc coagulation factor can be activated, adhere on the wound of oozing of blood, the blood vessel to damaging plays a part of filling.The rack body of the present invention is network structure, is easy to the extension of support.The rack body of the present invention has extendible characteristic, takes care to be extended therewith during vasodilation, can't produce obstruction, it is ensured that the safety of user of service.The rack body outside parcel matcoveredn of the present invention, because rack body is made up of metal, protective layer is wrapped up internal stent body, it is to avoid metal and inside of human body are contacted, it is ensured that the health of user of service.

Specific embodiment
As illustrated, being further described to the present invention：
Embodiment 1
The present invention provides a kind of Novel cardiovascular support, including rack body 1, coating layer 2, biodegradation layer 3, medicine layer 4,
Protective layer 5, the outside of rack body 1 parcel matcoveredn 5, the outside of protective layer 5 is enclosed with medicine layer 4, and the medicine layer 4 of the inner side of rack body 1 is enclosed with biodegradation layer 3, and the outside of medicine layer 4 in the outside of rack body 1 is coating layer 2.Rack body 1 is network.Rack body 1 is expandable structure.The degradable macromolecule grafted branch heparin of biodegradation layer 3.Coating layer 2 is collagen film.The rack body 1 of the present invention is network structure, is easy to the extension of support.The rack body 1 of the present invention has extendible characteristic, takes care to be extended therewith during vasodilation, can't produce obstruction, it is ensured that the safety of user of service.The outside of the rack body 1 parcel matcoveredn 5 of the present invention, because rack body 1 is made up of metal, protective layer 5 is wrapped up internal stent body 1, it is to avoid metal and inside of human body are contacted, it is ensured that the health of user of service.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
