DELIVERY DEVICE FOR CONTROLLED DEPLOYMENT OF A REPLACEMENT VALVE

摘要

Are described herein delivery devices for delivering a prosthesis within a lumen or body cavity for implantation. A delivery system (10) can include a plurality of components which are moveable relative to each other. The delivery system can include a nose cone (28) which can cover at least a first end of the prosthesis (30), an outer elongate member (24) which can cover at least a second end of the prosthesis, and a tether (32) which can at least partially restrain the prosthesis from deployment.
