Abstract
A percutaneous valve delivery system may include an outer sheath and an inner catheter disposed within the outer sheath. The inner catheter may include a plurality of lumens formed therein. A tubular extension may extend distally from a distal end of the inner catheter, wherein the tubular extension is axially movable relative to the inner catheter. A nose cone may be attached to the tubular extension. A handle may be attached to the outer sheath, wherein the handle is configured to shift the outer sheath between a first position and a second position relative to the inner catheter. A valve replacement implant may be releasably coupled to the inner catheter.
