Patent ID: 8496700

Claim:
A delivery system for attachment of a bioprosthetic aortic valve to the annulus of a previously installed bioprosthetic aortic valve, the delivery systems comprising: a valve replacement instrument, the instrument having an outer tubular housing adapted to be inserted within an aortic root toward the previously installed bioprosthetic valve; and the outer tubular housing configured to receive an elongated body; the elongated body inserted into the inner cavity of the outer tubular housing; a bioprosthetic replacement valve assembly assembled in a folded position and configured in the interior of the outer tubular housing and positioned around the lead end of the elongated body, the bioprosthetic replacement valve assembly having a valve frame and a skirt, the valve frame including at least one strut valve extension associated with at least one temporary fastener and at least one bioprosthetic leaflet, and the bioprosthetic replacement valve assembly being configured to be deployed from the outer tubular housing upon the retraction of the outer tubular housing permitting the bioprosthetic replacement valve assembly to expand and be positioned adjacent to the annulus of a previously installed bioprosthetic aortic valve; and a displaceable cap configured to be advanced from the elongated body such that the at least one temporary fastener is unfolded and temporarily secures the valve assembly to the annulus of the previously installed bioprosthetic aortic valve; wherein the elongated body and the displaceable cap are configured to be retracted from the inner cavity of the outer tubular housing to allow for the outer tubular housing to receive an endovascular stapler.
