Aortic valve replacement
摘要：
A device for replacement of a bioprosthetic valve having an annulus (104) and one or more leaflets (105), the device having an outer housing (106) and an inner shaft (108) with a distal end (110). The outer housing (106) is slideable relative to the inner shaft (108) such that a portion of the inner shaft (108) may be revealed. A cap (112) is associated with the distal end (110) of the inner shaft (108), the cap (112) movable between a first position adjacent the inner shaft (108) and a second position displaced from the inner shaft (108). The cap (112) is adapted to trap a skirted valve frame (102) between said cap (112) and the inner shaft (108) when in the first position. The skirted valve frame (102) may be released by the cap (112) upon sliding of the outer housing (106) relative to the inner shaft (108) to reveal the inner shaft (108) and upon movement of the cap (112) to the second position. Also disclosed are associated methods.
摘要（中）：

一种用于更换具有环（104）和一个或多个小叶（105）的生物假体瓣膜的装置，所述装置具有外壳（106）和具有远端（110）的内轴（108）。 外壳（106）能够相对于内轴（108）滑动，使得可以露出内轴（108）的一部分。 帽（112）与内轴（108）的远端（110）相关联，帽（112）可在邻近内轴（108）的第一位置和从内轴（108）移位的第二位置之间移动 ）。 当处于第一位置时，帽（112）适于将裙带式阀架（102）捕获在所述盖（112）和内轴（108）之间。 当外壳（106）相对于内轴（108）滑动以便露出内轴（108）并且当盖（112）移动时，裙带式框架（102）可以被盖（112）释放， 到第二个位置。 还公开了相关联的方法。
