Abstract
A method of delivering a replacement prosthetic valve to a previously implanted prosthetic valve including the steps of compressing a replacement prosthetic valve having an expandable stent within a sheath of a delivery system, wherein the delivery system comprises a proximal end, a distal end, and a centering structure positioned between the proximal and distal ends, advancing the delivery system and compressed replacement prosthetic valve into a vessel of a patient until the distal end of the delivery system is positioned adjacent to a second side of a previously implanted prosthetic valve, deploying the centering structure to radially reposition the distal end of the delivery system, further advancing the delivery system toward the previously implanted prosthetic valve, and deploying the replacement prosthetic valve.
