Abstract

一种管腔支架，包括可在径向被压缩和展开的管体(10)和防漏结构(20)；管体(10)被防漏结构(20)分为位于防漏结构(20)一侧的第一管体(11)和位于防漏结构(20)另一侧的第二管体(12)，第一管体(11)至少有部分被防漏结构(20)围绕。压缩状态下，第二管体(12)、防漏结构(20)连同被防漏结构(20)围绕的第一管体(11)具有被沿管腔支架周向均匀分布的径向力压缩至极限时的最大压缩直径，且防漏结构(20)连同被防漏结构(20)围绕的第一管体(11)的最大压缩直径大致等于第二管体(12)的最大压缩直径。管腔支架在鞘管(30)内与鞘芯(31)的接触力更加均匀，能够防止管腔支架在释放过程中的滑动，避免了管腔支架移位带来的风险。
