Abstract
A replacement cardiac valve for placement adjacent the native annulus comprises a valve body having a multi-leaflet valve, a supporting stent surrounding and operatively coupled to the valve body, a superior O-ring and an inferior O-ring spaced from one another to span the native annulus, the O-rings surrounding the valve body and operatively coupled the valve body or the supporting stent, the valve body, the supporting stent, and the O-rings adapted for transcatheter placement using a deployment catheter.

17. A method of minimally-invasive valve replacement at a location adjacent a native annulus, the method comprising the steps of:
-
performing a balloon valvuloplasty on a native valve;
providing a replacement valve having a pair of O-rings surrounding a valve body;
guiding the replacement valve to a position adjacent the valve annulus of the native valve;
expanding the valve body at a positioned adjacent the valve annulus of the native valve; and
forming a paravalvular seal.
