Embodiment Construction

[0022] Preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, the present invention provides a vascular stent with an absorbable coating for treating intraluminal vascular malformations. The vascular stent with an absorbable coating includes: a tubular stent 1 and a coating unit 2, the tubular bracket 1 is a flexible tubular structure, including a proximal end, a middle part and a distal end arranged in sequence; the coating unit 2 is coated on the tubular on bracket 1. Wherein, the covering unit 2 is a braided structure, and the covering unit 2 is fixed on the outer surface of the tubular stent 1 by suturing absorbable sutures, and the sutures are made of absorbable materials. Alternatively, the coating unit 2 is fixedly coated on the outer surface of the tubular stent 1 by using a hot-melt process. Preferably, the tubular stent 1 is a single-layer structure; the covering...

Abstract

The invention discloses a vascular stent with absorbable films. The vascular stent comprises a tubular stent and a film unit. The tubular stent is of a flexible tubular structure and comprises a proximal end, a middle portion and a distal end which are sequentially arranged; the film unit is coated on the tubular stent; the film unit is made of degradable high-polymer materials. The vascular stenthas the advantages that the film unit can be absorbed by biological tissues, accordingly intimal hyperplasia and restenosis risks can be reduced, normal blood flow channels can be kept, and vascularstenosis can be effectively treated.

Description

technical field [0001] The invention relates to a blood vessel stent, in particular to a blood vessel stent with an absorbable coating. Background technique [0002] In order to avoid the high risk of surgery, endovascular interventional therapy has gradually become the main method for treating aneurysms. Endovascular interventional therapy has the advantages of less trauma, fewer complications, high safety, less pain for patients, and it can be tolerated even in old age and severe illness. . Covered stents, also known as covered stents, are composed of stents and thin-layer membranes, and refer to artificial in vivo grafts in which the inner or outer surfaces of bare tubular stents are partially or completely covered with membranous materials; using the supporting function of stents and the covering of membranes The function is to seal the ruptured or perforated blood vessels, and it can also be used to seal off aneurysms or arterial fistulas. The covered stent not only r...
