Abstract:
1. A method of delivering a replacement prosthetic valve to a previously implanted prosthetic valve, the method comprising: compressing a replacement prosthetic valve comprising an expandable stent within a first sheath of a delivery system, wherein the delivery system comprises a proximal end and a distal end; 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; partially retracting the first sheath of the delivery system toward the proximal end of the delivery system until a first distal portion of the expandable stent extends from a first end of the first sheath, wherein the extending first distal portion of the expandable stent extends radially relative to the first sheath; further advancing the delivery system toward the previously implanted prosthetic valve and engaging the extending first distal portion of the expandable stent with the second side of the previously implanted prosthetic valve; and retracting a second sheath of the delivery system toward the proximal end of the delivery system to expose the compressed stent and deploy the replacement prosthetic valve, wherein a second distal portion of the expandable stent radially extends to engage with a first side of the previously implanted prosthetic valve.
