Methods and apparatus for delivering a prosthetic valve to a beating heart
First Claim
1. A method for delivering a prosthetic valve to a patient'"'"'s heart having a native valve with a plurality of valve leaflets, said method comprising:
- providing a delivery device having a prosthetic valve with a longitudinal axis;
advancing the delivery device toward the native valve;
expanding a portion of the prosthetic valve to form a flanged region, the flanged region disposed upstream of the valve leaflets;
rotationally aligning the prosthetic valve with the native valve;
rapid pacing the patient'"'"'s heart such that the plurality of valve leaflets move inward toward the prosthetic valve; and
releasing one or more tabs from the prosthetic valve to anchor the valve by disposing at least a portion of the one or more tabs behind at least one of the valve leaflets.

Abstract
A method for delivering a prosthetic valve to a patient'"'"'s heart having a native valve with a plurality of valve leaflets includes providing a delivery device with a prosthetic valve, advancing the delivery device toward the native valve, and expanding a portion of the prosthetic valve to form a flanged region that is upstream of the valve leaflets. One or more tabs on the prosthetic valve are released so that they expand outward to a position that is transverse to the longitudinal axis of the prosthetic valve. The position of the prosthetic valve is adjusted relative to the valve leaflets and rapid pacing is applied to the patient'"'"'s heart so that the valve leaflets move inward toward the prosthetic valve or the delivery device. The tabs are further released to allow the tabs to move into their final positions.
