    摘要: A prosthetic heart valve includes a frame that is radially collapsible and expandable between a collapsed configuration and an expanded configuration, and defines a longitudinal axis. A leaflet structure situated within the frame, and a sealing member is disposed around the frame. The sealing member can include a first portion extending circumferentially around a portion of the frame, the first portion being configured to resiliently stretch in a direction along the longitudinal axis between a first state corresponding to the expanded configuration of the frame and a second state corresponding to the collapsed configuration of the frame. The sealing member can include a second portion extending circumferentially around a portion of the frame, the second portion being configured to resiliently stretch in a circumferential direction between a first state corresponding to the collapsed configuration of the frame and a second state corresponding to the expanded configuration of the frame.

    摘要: A valve holder for delivering a prosthetic heart valve to an implant site is in various embodiments configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. The valve holder can be configured to deploy or actuate automatically when performing preparatory steps that are already familiar to practitioners, such as attaching a delivery handle to the valve holder, so that the valve holders will not require additional steps or training to use. Therefore, operation of the valve holders is kept simple, and occurrences of mistakes caused by user error can be minimized or reduced. Valve holders according to different embodiments can be designed to accommodate implantation of prosthetic heart valves from either the inflow end or the outflow end of the native valve annulus.

    摘要: Methods for replacing a native heart valve. An anchor comprises coils adapted to support a heart valve prosthesis. The anchor is positioned at a native heart valve. An expansible heart valve prosthesis is delivered into the anchor and expanded inside the coils. This moves at least one coil from a first diameter to a second, larger diameter while securing the anchor and the heart valve prosthesis relative to each other. The heart valve prosthesis comprises a seal on the expansible heart valve prosthesis. Additional apparatus and methods are disclosed.
