Abstract
A prosthetic device including a valve-orifice attachment member attachable to a valve in a blood vessel and including a fluid inlet, and a diverging member that extends from the fluid inlet, the diverging member including a proximal end near the fluid inlet and a distal end distanced from the proximal end, wherein a distal portion of the diverging member has a larger cross-sectional area for fluid flow therethrough than a proximal portion thereof. The diverging member may have a diverging taper that causes fluid to flow therethrough with pressure recovery at the distal end thereof.
Claims23
Prosthetic apparatus comprising:
- a support frame, configured for attachment to a native valve site of a patient, and shaped to define:
- a converging frame inlet section, and
- a diverging frame downstream section;
- and
- an envelope shaped to define:
- a converging envelope inlet, conforming generally to the converging frame inlet section, and
- a diverging envelope section, conforming generally to the diverging frame downstream section, supported by the frame, and configured to open and close in accordance with a cardiac cycle of the patient.
A method, comprising:
- identifying a stenotic native valve site of a heart of a patient;
- and
- implanting at the native valve site:
- a support frame, configured for attachment to the native valve site, and shaped to define:
- a converging frame inlet section, and
- a diverging frame downstream section;
- and
- an envelope shaped to define:
- a converging envelope inlet, conforming generally to the converging frame inlet section, and
- a diverging envelope section, conforming generally to the diverging frame downstream section, supported by the frame, and configured to open and close in accordance with a cardiac cycle of the patient.
