Abstract
A prosthetic valve delivery device includes a handle and a delivery catheter. The delivery catheter includes a central elongate member extending from the handle and a proximal sheath configured to slide over and relative to the central elongate member. The proximal sheath is connected to a hollow helical strand, and the hollow helical strand is configured to rotate to retract the proximal sheath and expose at least a portion of the prosthetic valve.
