Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame having an inflow end, an outflow end, and a longitudinal axis. A leaflet structure is positioned within the frame and secured thereto, and a sealing element is secured to the frame. The sealing element includes a first woven portion extending circumferentially around the frame. The first woven portion includes a plurality of interwoven filaments. The sealing element further includes a second woven portion extending circumferentially around the frame and spaced apart from the first woven portion along the longitudinal axis of the frame. At least a portion of the filaments exit the weave of the first woven portion and form loops extending radially outwardly from the frame.

Abstract: Disclosed herein are reinforced expandable introducer sheaths and methods of using the same. The sheaths minimize trauma to the patient's vasculature by including a reinforcing member to improve the push force of the sheath while reducing the chances of kinking during delivery of a prosthetic device. The sheath can include a plurality of expandable rings aligned along the longitudinal axis of the sheath and coupled together to form an elongated tubular structure. The sheath can also include a plurality of radial members circumferentially arranged to form a tubular support structure. The radial members slidingly interconnected around the circumference of the tubular structure to facilitate radial expansion of the sheath.

Abstract: The expandable sheath and methods of use disclosed herein are used to deliver a prosthetic device through a patient's vasculature. The sheath is constructed to be expandable in the circumferential direction, while maintaining sufficient stiffness in the longitudinal direction to withstand pushing and resist kinking. The sheath includes a plurality of curved arms extending outwardly from a longitudinally extending spine. The curved arms move away from the longitudinal axis of the sheath when pushed radially outwardly by a passing prosthetic device, and move back toward the longitudinal axis once the prosthetic device has passed.

Abstract: A covering layer for a transcatheter heart valve is in various embodiments configured to prevent or reduce damage to the native valve tissue around the site where the prosthetic valve is implanted. In some cases, prosthetic valves are manufactured with the covering layer attached. Other covering layers are stand-alone accessories that can be mounted onto pre-existing prosthetic valves by an end user. Covering layers that can be mounted by an end user are provided with various features that can facilitate easier attachment of the covering layer to the prosthetic valve, which further reduces the possibility of damage to the covering layer or to the valve. Another covering is provided with two layers in order to insulate and protect the native tissue surrounding the implant from damage due to friction or abrasion, and/or other movement driven wear.

Abstract: Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.

Abstract: A prosthetic heart valve includes an annular frame including a plurality of strut members that is radially collapsible and expandable. A leaflet structure is situated within the frame, and includes a plurality of leaflets having opposing commissure tab portions on opposite sides of the leaflet. Each commissure tab portion is paired with an adjacent commissure tab portion of an adjacent leaflet to form one or more commissures. A commissure support element is positioned at each of the commissures, and comprise a first member and a second member that are separable from each other and configured to receive leaflets therebetween. The first and second members are detached from the frame and spaced radially inwardly from the frame such that the members contact the leaflets radially inward from the frame and limit movement of the leaflets so that they articulate at a location that is spaced radially inwardly from the frame.

Abstract: An assembly can comprise a radially expandable and compressible annular frame, at least one linear actuator assembly coupled to the frame and at least one locking mechanism coupled to the frame. The linear actuator can be configured to apply a distally directed force and/or a proximally directed force to the frame to radially expand or compress the frame. The locking mechanism can comprise a first sleeve member connected to the frame at a first location, a second sleeve member having internal threads and being connected to the frame at a second location, and a first screw configured to engage the internal threads of the second sleeve member to retain the frame in a radially expanded state.

Abstract: A prosthetic valve includes an annular frame and a skirt. The frame is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The skirt has a fold around an inflow end of the frame so as to cover at least a portion of an outer surface of the frame and at least a portion of an inner surface of the frame. When the frame is in the radially expanded configuration, an outer portion of the skirt tightly conforms to the outer surface of the frame and the inflow end of the frame is axially spaced from the fold to form an axially extending gap between the frame and the fold. When the frame is in the radially compressed configuration, the inflow end of the frame extends axially so as to at least partially fill the axially extending gap.

Abstract: An expandable docking station includes an annular valve seat having an end, an annular outer wall comprising struts disposed around the valve seat, and links that connect the end of the annular valve seat to the annular outer wall. Each of the links extends from the struts of the annular outer wall directly toward a longitudinal axis that runs longitudinally through a center of the docking station, and to a corresponding one of a plurality of circumferentially spaced axially extending legs at least partially defining the annular valve seat. The outer wall is configured to conform to an interior shape of a blood vessel, when expanded inside the blood vessel, such that the outer wall can expand in multiple locations to conform to multiple bulges of the blood vessel and can contract in multiple locations to conform to multiple narrowed regions of the blood vessel.
