Two piece heart valves including multiple lobe valves and methods for implanting them
First Claim
1. A multiple component heart valve assembly, comprising:
- an annular prosthesis implantable within a natural valve annulus, the annulus prosthesis comprising an annular member disposed around a central longitudinal axis for dilating tissue surrounding the annulus;
a prosthetic valve separate and disconnected from the annular prosthesis, the prosthetic valve comprising a frame having a multiple lobular outer shape radially relative to the longitudinal axis for implantation above the natural valve annulus;
one or more connectors for securing the prosthetic valve to the annular prosthesis after the annular prosthesis has been introduced into the natural valve annulus; and
a flexible skirt extending radially from at least one of the annular prosthesis and the prosthetic valve the skirt being deformable to accommodate irregularities between the annular prosthesis and the frame for enhancing a seal between the prosthetic valve and the annular prosthesis.

Abstract
A heart valve assembly including an annular prosthesis implantable within a biological annulus, a prosthetic valve including a multiple lobular shape for implantation above the biological annulus, and one or more connectors for securing the prosthetic valve to the annular prosthesis. A flexible sewing cuff extends radially from the annular prosthesis that is resiliently flexible for conforming to the multiple lobular shape of the prosthetic valve to enhance a seal between the prosthetic valve and the annular prosthesis. The sewing cuff may include a core resiliently conformable with anatomy surrounding the biological annulus and fabric covering at least a portion of the core.

17. A multiple component heart valve assembly, comprising:
-
an annular prosthesis implantable within a biological annulus, the annular prosthesis comprising a substantially circular annular member disposed around a central longitudinal axis for introduction into a biological annulus; a prosthetic tissue valve separate and disconnected from the annular prosthesis, the prosthetic valve comprising a multiple lobular outer shape radially relative to the longitudinal axis for implantation above the biological annulus; one or more connectors for securing the prosthetic tissue valve to the annular prosthesis after the annular prosthesis has been introduced into the natural valve annulus; and a flexible skirt extending radially from at least one of the annular prosthesis and the prosthetic tissue valve for enhancing a seal between the prosthetic tissue valve and the annular prosthesis. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
