Abstract
A prosthetic valve has a radially expandable and compressible frame including a plurality of interconnected struts and a valvular structure including a plurality of leaflets configured to regulate the flow of blood through the prosthetic valve. The leaflets can have undulating cusp edge portions. The prosthetic valve further includes at least one connecting skirt having a shape that corresponds to the cusp edge portion of at least one leaflet. The connecting skirt can connect the cusp edge portion of the leaflet to at least one of the struts of the frame. The connecting skirt can include a first set of yarns intersecting with a second set of yarns. The first and second sets of yarns can extend at oblique angles relative to a longitudinal axis of the at least one strut.
Claims18
A prosthetic valve comprising:
- a radially expandable and compressible frame comprising a plurality of interconnected struts;
- a valvular structure comprising a plurality of leaflets configured to regulate the flow of blood through the prosthetic valve, the leaflets having undulating cusp edge portions;
- and
- at least one connecting skirt having a shape that corresponds to the cusp edge portion of at least one leaflet;
- wherein the connecting skirt connects the cusp edge portion of the leaflet to at least one of the struts of the frame;
- wherein the connecting skirt comprises a first set of yarns intersecting with a second set of yarns, wherein the first and second sets of yarns extend at oblique angles relative to a longitudinal axis of the at least one strut;
- wherein a first longitudinal edge portion of the connecting skirt is coupled to the cusp edge portion of the leaflet, and a second longitudinal edge portion of the connecting skirt is coupled to the at least one strut, the second edge portion being opposite the first edge portion.
A prosthetic valve comprising:
- a radially expandable and compressible frame comprising a plurality of interconnected struts, wherein the frame comprises an inflow end and an outflow end;
- a valvular structure comprising a plurality of leaflets configured to regulate the flow of blood through the prosthetic valve, the leaflets having undulated cusp edge portions;
- and
- a connecting skirt having undulated shape that corresponds to a shape of the cusp edge portions;
- wherein the connecting skirt connects the cusp edge portions of the plurality of leaflets to struts of the frame that extend diagonally relative to the inflow and outflow ends of the frame;
- wherein the connecting skirt comprises a first set of yarns interwoven with a second set of yarns, wherein the first set of yarns extend at an oblique angle relative to the struts connected to the connecting skirt.
A method for mounting a valvular structure comprising a plurality of leaflets to a radially expandable and compressible frame, the method comprising:
- coupling at least one leaflet to a connecting skirt;
- and
- coupling the connecting skirt to a strut of the frame that extends diagonally along a line extending from an inflow end of the frame to an outflow end of the frame;
- wherein the connecting skirt comprises a first set of yarns interwoven with a second set of yarns, wherein the connecting skirt is oriented such that the first set of yarns extend at an oblique angle relative to a longitudinal axis of the strut;
- wherein coupling the leaflet to the connecting skirt comprises coupling a first longitudinal edge portion of the connecting skirt to the cusp edge portion of the leaflet, and coupling the connecting skirt to the strut of the frame comprises coupling a second longitudinal edge portion of the connecting skirt to the strut, the second edge portion being opposite the first edge portion.
