Abstract
Methods and systems for introducing a delivery device, having a prosthesis, in the heart at or near the apex of the heart are provided. The methods include the steps of piercing the apex of the heart with a tissue piercing end of the delivery device, 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 are configured to deliver a replacement heart valve to a target site in or near a heart. The valve replacement system includes 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 optionally includes mechanical or inflatable expanding members for implantating the prosthetic valve at the target site.
