Aortic insufficiency valve percutaneous valve anchoring
First Claim
1. A method of implanting a stented device in a cardiovascular system of a mammalian subject, the method comprising:
- guiding a delivery device having an anchoring device connected to a distal end thereof within the cardiovascular system to a target location, the anchoring device having a body and a mooring feature extending from the body;
anchoring the anchoring device at the target location by penetrating tissue at the target location with the mooring feature, the mooring feature being configured to anchor the body to the tissue when penetrated therein;
guiding the stented device through the cardiovascular system to the target location; and
deploying the stented device such that a native valve leaflet is positioned between a stent of the stented device and the anchoring device and so that, when the native valve leaflet is positioned between the stented device and the anchoring device, the stented device and the anchoring device together pinch the native valve leaflet to create a pinching effect on the native valve leaflet so as to restrict movement of the stented device within the cardiovascular system.

Abstract
A method of implanting a stented device in a cardiovascular system of a mammalian subject includes guiding a delivery device that has an anchoring device connected to a distal end thereof within the cardiovascular system to a target location. The anchoring device has a body and a mooring feature extending from the body. The anchoring device is anchored at the target location by penetrating tissue at the target location with the mooring feature. The mooring feature is configured to anchor the body to the tissue when penetrated therein. The stented device is then guided through the cardiovascular system to the target location and deployed such that a stent of the stented device engages the anchoring device so as to restrict movement of the stented device within the cardiovascular system.

10. A method of implanting a valvular prosthesis in a cardiovascular system of a mammalian subject, the method comprising:
-
percutaneously guiding first and second anchoring devices to respective first and second locations within the cardiovascular system, the first and second anchoring device each having a body and a mooring feature extending from the body; anchoring the first anchoring device to tissue at the first location and the second anchoring device to tissue at the second location via the mooring feature of the respective first and second anchoring devices; percutaneously guiding the valvular prosthesis within the cardiovascular system to a position between the first and second locations; and deploying the valvular prosthesis so that a first native valve leaflet is positioned between a stent of the valvular prosthesis and the first anchoring device and a second native valve leaflet is positioned between the stent of the valvular prosthesis and the second anchoring device and so that, when the first and second native valve leaflets are positioned between the valvular prosthesis and first and second anchoring device, the stent and the first and second anchoring devices together pinch the first and second native leaflets to create a pinching effect on the first and second native valve leaflets, respectively, to restrict movement of the valvular prosthesis within the cardiovascular system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
