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.
