Abstract
A prosthetic heart valve and delivery device for delivering the prosthetic heart valve to a target implantation site, which reduce contact between the prosthetic heart valve and a delivery sheath through which the delivery device is advanced to the target implantation site, is disclosed. As one example, a prosthetic heart valve may comprise a frame including a first end with a plurality of apices spaced apart from one another around a circumference of the first end and a cover element covering the plurality of apices. The cover element may include a cushioning element or a bio-resorbable element.
Claims15
A prosthetic heart valve, comprising:
- a radially expandable and compressible frame including a first end with a plurality of apices spaced apart from one another around a circumference of the first end;
- a plurality of leaflets secured to one another at their adjacent sides to form a plurality of commissures spaced circumferentially apart from each other, wherein the plurality of commissures is coupled to the frame, and wherein at least one apex of the plurality of apices is disposed circumferentially between two adjacent commissures of the plurality of commissures and spaced circumferentially away from each commissure of the two adjacent commissures;
- and
- a plurality of discrete cushioning elements covering the plurality of apices, wherein each cushioning element of the plurality of cushioning elements is coupled to and covers a different apex of the plurality of apices, wherein each apex comprises an axially facing surface forming a tip of the apex, and wherein each cushioning element extends radially across and covers the axially facing surface of a corresponding apex.
The prosthetic heart valve of any one of the preceding claims, wherein each cushioning element comprises a plurality of folds arranged over and across the axially facing surface of the corresponding apex of the plurality of apices.
A prosthetic heart valve, comprising:
- a frame including a first end with a plurality of apices spaced apart from one another around a circumference of the first end;
- and
- a plurality of discrete cushioning elements covering the plurality of apices, wherein each cushioning element of the plurality of cushioning elements is coupled to and covers a different apex of the plurality of apices, wherein each cushioning element comprises an inner layer covering an inner surface of a corresponding apex of the plurality of apices, an outer layer covering an outer surface of the corresponding apex, and a distal layer defining a distal surface of the cushioning element and extending radially from the inner layer to the outer layer and across a distal edge of the corresponding apex.
A prosthetic heart valve, comprising:
- a radially compressible and expandable frame including a first end with a plurality of apices spaced apart from one another around a circumference of the first end;
- a plurality of leaflets secured to one another at their adjacent sides to form a plurality of commissures spaced circumferentially apart from each other, wherein the plurality of commissures is coupled to the frame, and wherein at least one apex of the plurality of apices is disposed circumferentially between two adjacent commissures of the plurality of commissures and spaced circumferentially away from each commissure of the two adjacent commissures;
- and
- a plurality of discrete cushioning elements covering the plurality of apices, wherein each cushioning element of the plurality of cushioning elements is coupled to and covers a different apex of the plurality of apices, and wherein each cushioning element comprises fabric.
