ENDOVASCULAR AORTIC REPAIR DELIVERY SYSTEM WITH ANCHOR

摘要

PROBLEM TO BE SOLVED: To provide an EVAR delivery system that minimizes compressive forces on the prosthesis and provides smooth delivery and accurate positioning of the prosthesis in the vasculature.

SOLUTION: The delivery system includes a primary elongated member positioned coaxially within the prosthesis. A secondary elongated member surrounds a portion of the primary elongated member and a portion of the secondary elongated member is positioned coaxially within the prosthesis. The delivery system further includes a proximal anchor attached to the secondary elongated member. The anchor is adapted for engagement with the proximal end of the prosthesis, thereby maintaining the prosthesis in its radially compressed configuration. At least one outer sheath is adapted to be retracted to expose the prosthesis while the prosthesis is maintained in its radially compressed configuration. The primary elongated member and the secondary elongated member are axially movable relative to one another to disengage the prosthesis from the anchor and permit expansion of the radially compressed prosthesis.
