Abstract
An implantable prosthetic valve can comprise an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, the frame defining an axial direction extending from the inflow end to the outflow end, a leaflet structure positioned within the frame and secured thereto, and an outer sealing member positioned around an outer surface of the frame, wherein the outer sealing member comprises a plurality of sealing segments, wherein each sealing segment is coupled to the frame and/or another sealing segment by a tether that pulls a portion of the sealing segment in a circumferential direction when the frame is radially expanded to the expanded configuration.

An implantable prosthetic valve comprising:
- an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, the frame defining an axial direction extending from the inflow end to the outflow end;
- a leaflet structure positioned within the frame and secured thereto;
- and
- an outer sealing member positioned around an outer surface of the frame, wherein the outer sealing member comprises a plurality of sealing segments;
- wherein each sealing segment is coupled to the frame and/or another sealing segment by a tether that pulls a portion of the sealing segment in a circumferential direction when the frame is radially expanded to the expanded configuration.
An implantable prosthetic valve comprising:
- an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, the frame defining an axial direction extending from the inflow end to the outflow end;
- a leaflet structure positioned within the frame and secured thereto;
- and
- an outer sealing member positioned around an outer surface of the frame, wherein the outer sealing member comprises a plurality of sealing segments;
- wherein each sealing segment is coupled to the frame and/or another sealing segment by a first tether that pulls a first longitudinal edge portion of the sealing segment in a first circumferential direction and a second tether that pulls a second longitudinal edge portion of the sealing segment in a second circumferential direction, when the frame is radially expanded to the expanded configuration.
An implantable prosthetic valve comprising:
- an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, the frame defining an axial direction extending from the inflow end to the outflow end;
- a leaflet structure positioned within the frame and secured thereto;
- and
- an outer sealing member positioned around an outer surface of the frame, wherein the outer sealing member comprises a plurality of sealing segments, wherein each sealing segment extends longitudinally, in the axial direction, between an upper edge portion and a lower edge portion of the outer sealing member and has a width defined between a first longitudinal edge portion and a second longitudinal edge of the sealing segment;
- and
- wherein each sealing segment is coupled to the frame and/or another sealing segment by at least a first tether that pulls a portion of the sealing segment in a circumferential direction such that the width of the sealing segment between its upper and lower ends decreases and forms longitudinal folds in the sealing segment when the frame is radially expanded to the expanded configuration, wherein the portion of the sealing segment is one of the first longitudinal edge portion and the second longitudinal edge portion of the sealing segment.
