<p>A method and systems for introducing a delivery device in the heart (12) at or near the apex of the heart, wherein the delivery device includes a prosthesis (29), advancing the prosthesis to the target site, and disengaging the prosthesis from the delivery device at the target site for implantation. The valve replacement systems deliver a replacement heart valve to a target site in or near a heart. The valve replacement system comprises a trocar or other suitable device to penetrate the heart at or near the apex of the heart, a delivery member that is movably disposed within the trocar, and a replacement cardiac valve disposed on the delivery member. The delivery member may further comprise mechanical or inflatable expanding members to facilitate implantation of the prosthetic valve at the target site.</p> |
