1. A method of implanting a prosthetic valve assembly into a target site comprising:
- inserting at least a portion of the valve assembly into the target site in a distal direction;
allowing a distal portion of the valve assembly to flare radially such that the radially flared distal portion engages tissue of the target site; and
releasing a remaining portion of the valve assembly.

Abstract
A device and method for improving flow through a native blood vessel valve, such as the aortic valve, are provided. The present invention allows a miniature valve to be implanted into affected leaflets percutaneously, obviating the need for coronary bypass surgery. The method includes the cutting of small holes, on the order of 4 mm, in the leaflets of a targeted valve, thereby allowing blood to flow through the newly formed holes. The holes are used as attachment sites for the miniature valves of the present invention.
