1. An anchoring device for a device intended for implantation at a native heart valve annulus, said anchoring device comprising:
- a central portion with one or more anchors extending therefrom, each of said one or more anchors having a proximal fixed end secured to the central portion and terminating in free end, said one or more anchors being spaced slightly away from and running substantially parallel to the circumference of the central portion in a curved fashion, forming valve leaflet-receiving slots between the anchors and the central portion.

Abstract
A 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.

17. A method of implanting a device at a native valve annulus, comprising:
-
providing a device comprising a central portion, a first curved anchor extending from a first fixed end secured to the central portion and passing generally parallel to an outer surface thereof to a first free end of the first curved anchor to form a first leaflet-receiving slot, a second curved anchor extending from a second fixed end secured to the central portion and passing generally parallel to an outer surface thereof to a second free end to form a second leaflet-receiving slot, wherein the central portion defines a flow orifice with a fluid flow axis therethrough; positioning the device with the first curved anchor and second curved anchor adjacent the native valve annulus, with the fluid flow axis of the device generally parallel to a fluid flow path through the native valve annulus, and with the first free end positioned adjacent a first commissure of a resident heart valve at the native valve annulus; placing the first free end underneath a first resident valve leaflet; rotating the device substantially about the fluid flow axis thereof to advance the first free end underneath the first resident valve leaflet and thereby slidingly advancing the first resident valve leaflet into the first leaflet-receiving slot; monitoring the position of the second free end with respect to a second commissure of the resident heart valve; stopping rotation of the device about the fluid flow axis once the second free end is adjacent the second commissure of the resident heart valve; placing the second free end underneath a second resident valve leaflet; recommencing rotating the device substantially about the fluid flow axis thereof to advance the second free end underneath the second resident valve leaflet and thereby slidingly advancing the second resident valve leaflet into the second leaflet-receiving slot while also further advancing the first free end underneath the first resident valve leaflet and further slidingly advancing the first resident valve leaflet into the first leaflet-receiving slot; and stopping rotation of the device when the first resident valve leaflet is slidingly advanced into the first leaflet-receiving slot at a position adjacent the first fixed end, whereby deployment of the device is completed. - View Dependent Claims (18, 19, 20)
