US Patent:

20210315692, Oct 14, 2021

Filed:

Jun 24, 2021

Appl. No.:

17/357816

Inventors:

- Irvine CA, US
Luca Pesce - Huntington Beach CA, US
Glen T. Rabito - Lake Forest CA, US
Christine Thanh Nguyen - Santa Ana CA, US

Assignee:

Edwards Lifesciences CardiAQ LLC - Irvine CA

International Classification:

A61F 2/24

Abstract:

A prosthesis for placement within a native heart valve preferably includes an expandable frame having locking tabs disposed along a proximal end. A plurality of distal anchors is disposed along a distal end of the frame. Each distal anchor is provided with a cushion cover. An outer fabric member surrounds the frame and may extend outwardly from the frame in an expanded condition for providing an improved seal in the region of a native annulus. A valve body is positioned within an interior of the expandable from for allowing blood flow in only one direction. In preferred embodiments, the cushions are positioned over enlarged head portions of the distal anchors for further reducing trauma on surrounding tissue.

International Classification:

A61F 2/24

Abstract:

Devices for assisting with the functioning of a tricuspid valve of a heart include a shaft, a flow optimizer, and an anchoring mechanism. A tilting mechanism can be configured to tilt the shaft relative to a central axis of the anchoring mechanism. Leaflets (e.g., multi-layer leaflets) of the flow optimizer can include a membrane and a rim, and the rim can have a higher stiffness than the membrane.

Abstract:

A prosthesis for placement within a native mitral valve includes an expandable frame having locking tabs disposed along a proximal end. A plurality of distal anchors are disposed along a distal end of the frame. Each distal anchor is provided with a cushion cover. An outer fabric member surrounds the frame and may extend outwardly from the frame in an expanded condition for providing an improved seal in the region of a mitral annulus.

Assignee:

Edwards Lifesciences CardiAQ LLC - Irvine CA

International Classification:

A61F 2/24

Abstract:

A prosthesis can be configured to grasp intralumenal tissue when deployed within a body cavity and prevent axial flow of fluid around an exterior of the prosthesis. The prosthesis can include an expandable frame configured to radially expand and contract for deployment within the body cavity, and an annular flap positioned around an exterior of the expandable frame. In some embodiments, the annular flap can extend outward from the frame and have a collapsed configuration and an expanded configuration.
