METHOD AND APPARATUS FOR REPLACING A MITRAL VALVE WITH A STENTLESS BIOPROSTHETIC VALVE

Document Type and Number:

WIPO Patent Application WO2004032796

Kind Code:

A3

Abstract:

A stentless bioprosthetic valve includes at least one piece of biocompatible material comprising a bi-leaflet conduit having a proximal end and a distal end. The proximal end defines a first annulus for suturing to the valve annulus. The conduit includes first and second leaflets that mimic the native leaflets and extend between the conduit ends. The distal end defines a second annulus at which the first and second leaflets terminate. The conduit further includes first and second pairs of prosthetic chordae projecting from the leaflets at the second annulus. One of the first pair of prosthetic chordae extends from the first leaflet and has a distal end for suturing to a papillary muscle and the other of the first pair of prosthetic chordae extends from the first leaflet and has a distal end for suturing to another papillary muscles.
