Abstract
A heart valve assembly comprises a first prosthesis configured to expand from an unexpanded state to an expanded state at which the first annular prosthesis contacts native tissue of a body lumen. The heart valve assembly also comprises a second prosthesis comprising a valve, and a connection adapter that secures the second prosthesis to the first prosthesis, the connection adapter having a multi-lobed circumference.
Claims18
A prosthetic valve assembly comprising:
- a first annular prosthesis having a frame configured to have a first diameter in a collapsed state for introduction into a body lumen and a second diameter in an expanded state for implantation within an annulus of a heart, the first annular prosthesis having a first alignment element, wherein the first alignment element is a groove that extends in parallel with a longitudinal axis of the first annular prosthesis;
- and
- a second annular prosthesis including a prosthetic valve, the second annular prosthesis having a second alignment element that is configured to align with the first alignment element when the second annular prosthesis is positioned within the first annular prosthesis in the expanded state.
A prosthetic valve assembly comprising:
- a first annular prosthesis configured to be implantable into an annulus within a heart, the first annular prosthesis including a frame that is circumferentially expandable from a first diameter in a collapsed state for introduction into a body lumen to a second diameter in an expanded state for implantation within the annulus of a heart, the first annular prosthesis having a first engagement element and a first alignment element, the first alignment member being a groove;
- and
- a second annular prosthesis including a prosthetic valve, the second annular prosthesis having a second engagement element and a second alignment element, the second alignment member being a rib that is configured to slide within the groove,
- wherein the first engagement element and the second engagement element are configured to engage each other to attach the first and second annular prostheses together in vivo, and
- wherein the groove of the first alignment element slides within the rib of the second alignment element, when the first annular prosthesis and the second annular prosthesis are brought into engagement with each other in vivo, to longitudinally align the second annular prosthesis with the first annular prosthesis as the second annular prosthesis is inserted into engagement with the first annular prosthesis.
