DELIVERY DEVICE HAVING A CURVED SHAFT AND A STRAIGHTENING MEMBER FOR TRANSCATHETER AORTIC VALVE IMPLANTATION |
摘要 |
A delivery device (100) includes a support member (128), a distal sheath (130), an outer shaft (120) and a strengthening member (140). The support member is adapted to hold a prosthetic heart valve. The distal sheath is slidable relative to the support member between a first position in which the distal sheath is adapted to maintain the prosthetic heart valve in a collapsed condition, and a second position in which the distal sheath is adapted to expose the prosthetic heart valve. The outer shaft is connected to the distal sheath and has a curved portion (134). The straightening member is slidable on the outer shaft between a proximal position in which the straightening member does not cover the curved portion of the outer shaft, and a distal position in which the straightening member covers and substantially straightens at least a portion of the curved portion of the outer shaft. |
