HEART VALVE DELIVERY SYSTEM |
摘要 |
A delivery system for delivering a prosthetic heart valve (11) to a native valve site within the human vasculature. The prosthetic valve is disposed on a balloon (252) at the end of a balloon catheter. The balloon catheter passes through a delivery sleeve assembly and handle. A pull wire travels from the handle to a distal end of the delivery sleeve assembly. Actuation of the handle pulls on the pull wire, which causes openings in a slotted tube (20) of the delivery sleeve assembly to close, thus causing the delivery sleeve assembly to bend. A stretchable cover is placed over the slotted tube for biasing the steerable catheter toward a straight position. Once advanced to the native valve site, the prosthetic valve is deployed by inflating the balloon. |
