Abstract
A method and device for anchoring a prosthetic heart valve or annuloplasty ring to a valve annulus in a heart and a method of implanting same is disclosed. The device can include a prosthetic valve or annuloplasty ring with one or more anchors configured to be threaded or otherwise passed underneath a native leaflet and/or subvalvular tissue to secure the device at the native annulus.
Claims21
An anchoring device for an implant intended for implantation at a native heart valve annulus having valve leaflets, the anchoring device comprising:
- a circular or generally D-shaped central portion with a plurality of elongated distinct anchors extending therefrom, each of the plurality of anchors having a fixed end secured to the central portion opposite a free end so that each anchor is cantilevered from the central portion, the plurality of anchors being spaced away from and running substantially parallel to a circumference of the central portion in a curved fashion through an angle of between 90-240° to form valve leaflet-receiving slots between the anchors and the central portion, the slots have a length of 0.25 to 3.5 inches to receive the leaflets, wherein the anchors all extend in the same angular direction relative to each other.
An anchoring device for an implant intended for implantation at a native heart valve annulus having valve leaflets, the anchoring device comprising:
- a circular or generally D-shaped central portion extending around a circumference and a plurality of anchors each having a fixed end secured to the central portion opposite a free end so that each anchor is cantilevered from the central portion, each anchor extending in continuous, unbroken fashion from the fixed end to the free end substantially parallel to and spaced from the curved circumference of the central portion, and each anchor extending from a different angular position around the central portion and extending in the same angular direction, the anchors being non-over-lapping.
An anchoring device for an implant intended for implantation at a native heart valve annulus having valve leaflets, the anchoring device comprising:
- a circular or generally D-shaped central portion with a plurality of elongated distinct anchors extending therefrom, each of the plurality of anchors having a fixed end secured to the central portion opposite a free end so that each anchor is cantilevered from the central portion, the plurality of anchors being spaced away from and running substantially parallel to a circumference of the central portion in a curved fashion through an angle of between 90-240° to form valve leaflet-receiving slots between the anchors and the central portion, the slots have a length of 0.25 to 3.5 inches to receive the leaflets, wherein the central portion comprises two planar ring portions rotatable with respect to one another, and each ring portion has at least one anchor extending therefrom.
