Abstract

本发明专利为一种新型冠状动脉支架，属于医疗器械领域创新技术。目前上市的冠状动脉支架均是均一的筒状结构，在冠脉分支血管，或分叉血管狭窄需要置入支架时，因结构相对复杂，心脏在不停的跳动等因素，几乎不可能在冠脉分支口部置入支架。带定位环冠脉分支支架主体沿分支导丝走向分支，支架近端的定位环延主支导丝滑向主支；当支架到达主支与分支分叉处，支架主体已经进入分支，而近端因定位环的存在，准确的卡在分叉处，可以准确的把支架定位在分支的口部。该新型支架对分支病变治疗，分叉病变现行治疗技术，将有革新性的改进。

Description

带定位环冠脉分支支架
技术领域
本发明专利为一种新型冠状动脉支架，特别涉及冠脉分支病变，分叉病变，需要准确定位情况下置入的冠脉支架。
技术背景
近年来，冠状动脉支架技术已经成为介入治疗的常规技术。但是在冠脉分支血管，或分叉血管需要置入支架时，因结构相对复杂，心脏在不停的跳动等因素，导致精确定位置入支架十分困难。带定位环支架的诞生将彻底改变这个困境，使准确定位和冠状动脉分叉病变的手术方式，发生根本性改变和进步。
发明内容
目前所有上市的冠脉支架都是均一的筒状结构(11)，如附图1-6。支架在未扩张时，在冠状动脉内随心跳不停的滑动，无法准确的固定在分支的口部。支架扩张时，会定位在哪里很多时就靠运气了。带定位环冠脉分支支架在支架近端额外增加一个定位环结构(12，14)。该定位环与支架联为一体，环中央留有直径0.4mm孔道(13)，允许通过冠脉导丝；定位环为圆环/折叠环(折叠环可被动扩张为直径3.5-4.5mm圆环)，当支架主体沿分支导丝滑动，定位环沿主支导斯滑动，到达分叉部位时，支架边缘就被准确的卡在了分叉部位。

具体实施方式
对于单纯冠脉分支病变，选用带定位环(圆环)冠脉分支支架主体延导丝2导入分支，支架近端的定位环通过导丝1滑向主支；当支架到达主支与分支分叉处，支架主体已经进入分支，而近端因定位环的存在，准确的卡在分叉处，不能前进，从而可以准确的把支架定位在分支的口部(图7)。当分支支架充分扩张后，撤出分支内的球囊，及导丝1和导丝2，完成手术。若是分支与主支都需要处理的病变，选用折叠环冠脉分支支架。主支延主支导丝1进入另一球囊，按照主支直径扩张定位环到主支直径。然后在主支内，通过已经扩张的定位环，置入主支支架，完成分叉病变的支架置入(图8)。

Claims (2)
