Abstract
The utility model relates to an artery intraluminal bracket mainly used for restoring arterial blood vessels and relates to a medical component. The artery intraluminal bracket is mainly formed by a web roll and an axial connector, the web roll is formed jointly by connecting a ring unit and a web unit in order, the periphery of the axial connector is connected and fixed to form a cannular body and the cannualr body is externally covered with a film or cloth. The utility model is safe and reliable in use and mainly used for restoring damaged blood vessels.
Description
Technical field
This utility model relates to a kind of arterial vascular intracavity stent that is used to repair, and belongs to the medical device in the implantable vessel.
Background technology
At present, in the treatment of arterial disease, especially for diseases such as hemangioma, interlayer tumors, intra-arterial support introductory technique commonly used is treated, and is about to the lumen of artery inner support and sends into the arterial disease position, rebuilds arterial wall in lumen of artery, recovers the tremulous pulse normal blood flow.And existing lumen of artery inner support mostly is latticed greatly, or other shape, sends in the blood vessel by sending into device.But because the toughness or the uniform intensity of support cause, can not adapt to conditional request complicated in the blood vessel wall, as: the requirement of flexibility, the requirement of end anti-impact force etc., so safety and curative effect that support uses are affected.Especially the most frequently used latticed lumen of artery inner support, very easily torsional deformation hinders blood flow, easily because of blood flow is shifted, causes operative failure again; And the poor performance that the lumen of artery inner support of other shape changes with the bending of blood vessel, i.e. poor compliance, therefore the cure rate of operation is affected.
Summary of the invention
Problem to be solved in the utility model provides a kind of lumen of artery inner support rational in infrastructure, to adapt to situation complicated in the blood vessel, improves the dependability and the curative effect of support.
The designed lumen of artery inner support of this utility model mainly is made of looped network and axial connector, looped network is amounted to forming by annular unit and netted sequence of unit johning knot, be connected and fixed by axial connector periphery, form tubular body, the outside of tubular body is covered with film or cloth.
The annular unit of lumen of artery inner support is positioned at the end of support.
The annular unit of lumen of artery inner support be shaped as broken line shape, zigzag, waveform or rectangle etc.
For adapting to the specific (special) requirements at arterial disease position, the end of lumen of artery inner support can be abnormity.
For making the scope of application wider, also can be connected with arm in the end of above-mentioned lumen of artery inner support.The sidepiece of arm is connected by cloth, film or two lateral filaments at least.Arm can flip to the outside.
This utility model is when using, and is identical with the application of existing lumen of artery inner support, by sending into device the lumen of artery inner support sent into the vascular lesion place.Because the end of support is an annular unit, its intensity height is not subject to vascular pressure or blood and impacts torsional deformation, therefore has stronger impact resistance, plays the support positioning action, and lumen of artery inner support and blood vessel wall are fitted tightly; Netted unit in the support then has pliability preferably, can change with the bending of blood vessel, each position of support is all had preferably with blood vessel fits, strengthened the compliance of support, improve the success rate and the postoperative cure rate of arteries operation, and the support after the prolongation healing is in endovascular reliability and service life.

The specific embodiment
Embodiment 1
Lumen of artery inner support as shown in Figure 1 mainly is made of looped network and axial connector, and looped network is made up of the annular unit 1 and the intermediary netted unit 2 at two ends, is connected to form tubular body by axial connector periphery, and the outside of tubular body is covered with film 3.Annular unit 1 wherein is a broken line shape.
This kind lumen of artery inner support not only can change with vascular bending, and compliance is strong, and the location of end and anti-twist property are good, can improve the success rate of operation, improves the lumen of artery inner support in endovascular reliability and prolong in endovascular service life.
Another lumen of artery inner support as shown in Figure 2, the structural similarity of itself and embodiment 1 mainly is made of looped network and axial connector, and different is that looped network is made up of the annular unit 1 and the netted unit 2 of an end, be connected to form tubular body by axial connector periphery, the outside of tubular body is covered with cloth 3.Annular unit 1 be shaped as zigzag, its place end is the abnormity end, to adapt to the requirement of privileged sites blood vessel.This kind lumen of artery inner support has the advantage identical with embodiment 1, and can satisfy special requirement.
Another lumen of artery inner support as shown in Figure 3, the structural similarity of itself and embodiment 1 mainly is made of looped network and axial connector, and looped network is made up of the annular unit 1 and the intermediary netted unit 2 at two ends, be connected to form tubular body by axial connector periphery, the outside of tubular body is covered with film 3.The annular unit 1 of different is looped network one end has arm 4, and arm 4 can flip to the outside.Annular unit 1 is shaped as waveform in addition.This kind lumen of artery inner support has the advantage identical with embodiment 1, is applicable to the privileged sites of band branch vessel in the blood vessel.
The foregoing description is that several concrete schemes of this utility model are given an example, and protection domain is limit according to claim.
Claims (6)
1. lumen of artery inner support, mainly be made of looped network and axial connector, it is characterized in that: looped network is amounted to forming by annular unit and netted sequence of unit johning knot, is connected and fixed by axial connector periphery, form tubular body, the outside of tubular body is covered with film or cloth.
2. lumen of artery inner support according to claim 1, its feature also is: annular unit is positioned at the end of support.
