Abstract
A prosthetic heart valve having an orifice is configured to allow blood flow through an orifice. A suture cuff extends around an outer circumference of an outer ring. The suture cuff is adapted for attachment to a native tissue annulus of a patient. A weld between the suture cuff and the ring is configured to attach the suture cuff to the ring.
Claims43
A prosthetic heart valve, comprising,
- an outer orifice ring configured to allow blood flow therethrough;
- a first outer band adjacent a periphery of the outer orifice ring;
- a suture cuff including a fabric which extends around an outer circumference of the ring, the fabric being between the outer orifice ring and the first outer band, the suture cuff adapted for attachment to a native tissue annulus of a patient;
- and
- a weld which bonds the outer orifice ring to the first outer band to thereby attach the suture cuff to the outer orifice ring, the weld extending through the fabric.

A method of making a prosthetic heart valve, comprising:
- obtaining an outer orifice ring, the outer orifice ring configured to allow blood flow therethrough;
- positioning a suture cuff having fabric around an outer circumference of the outer orifice ring, the suture cuff adapted for attachment to a native tissue annulus of a patient through suturing;
- positioning a first, outer band along a periphery of the outer orifice ring adjacent the suture cuff such that the fabric of the suture cuff surrounds the first outer band and extends between the first outer band and the outer orifice ring;
- and
- welding the first outer band to the outer orifice ring through the fabric.

A prosthetic heart valve, comprising:
- an outer orifice ring configured to allow blood flow therethrough;
- a suture cuff comprising a fabric extending around an outer circumference of the ring, the fabric being positioned between the outer orifice ring and the suture cuff, the suture cuff adapted for attachment to a native tissue annulus of a patient;
- and
- a weld of the fabric of the suture cuff to the outer ring which bonds the fabric of the suture cuff directly to the outer ring to thereby attach the suture cuff to the outer ring.
