Abstract

本发明公开一种血管支架，支架的两端端部的外壁设置吸水膨胀体，吸水膨胀体的外表面设置防水降解体。本发明在血管支架植入血管一段时间后，防水降解体降解后，血液从缝隙流通过程中，吸水膨胀体吸收血液膨胀，跟血管壁紧密接触，彻底封堵，防止泄露；设置的防水降解体能够避免手术过程吸水膨胀体吸收膨胀，方便血管支架植入血管。

Description

血管支架
技术领域
本发明涉及医疗器械领域，具体来说是一种血管支架。
背景技术
以前在血管里面装支架，但支架与血管内壁之间会产生侧漏。导致支架无法定位，脱离与血管接触，脱离预安装位置。
因此，特别需要一种血管支架，以解决现有技术中存在的问题。
发明内容
本发明的目的是为了解决现有技术中，在血管里面装支架，但支架与血管内壁之间会产生侧漏的缺陷，提供一种血管支架，来解决现有技术中存在的问题。
为实现上述目的，本发明的技术方案如下：
一种血管支架，包括支架，所述支架的两端端部的外壁设置吸水膨胀体，所述吸水膨胀体的外表面设置防水降解体。
在本发明中，所述支架为金属支架。
有益效果
本发明公开一种血管支架，与现有技术相比，在支架的外壁设置吸水膨胀体和防水降解体，在血管支架植入血管一段时间后，防水降解体降解后，血液从缝隙流通过程中，吸水膨胀体吸收血液膨胀，跟血管壁紧密接触，彻底封堵，防止泄露；设置的防水降解体能够避免手术过程吸水膨胀体吸收膨胀，达到方便植入血管支架的效果。
附图说明
图1本发明的结构示意图。
图中：1、支架；2、吸水膨胀体；3、防水降解体。
具体实施方式
在全部附图的视图中，对应的参考符号表示对应的部件。
一种血管支架，包括支架1，支架1的两端端部的外壁设置吸水膨胀体2，吸水膨胀体2的外表面设置防水降解体3。
优选的实施方式中，支架1为金属支架1。
在使用的时候：血管支架放入血管内，支架1两端端部的吸水膨胀体2膨胀，对支架1位置进行限位，在一段时间后，吸水膨胀体2外表面的防水降解体3自动降解，使吸水膨胀体2的直径减小，可方便的取出血管支架。
上述的对实施例的描述是为便于该技术领域的普通技术人员能理解和使用本发明。熟悉本领域技术的人员显然可以容易地对这些实施例做出各种修改，并把在此说明的一般原理应用到其他实施例中而不必经过创造性的劳动。因此，本发明不限于上述实施例，本领域技术人员根据本发明的揭示，不脱离本发明范畴所做出的改进和修改都应该在本发明的保护范围之内。

Claims (3)
