ABSTRACT:
A stent delivery catheter comprising an elongated catheter shaft having a mounting region at the distal end for mounting a stent thereon. The elongated catheter shaft has a lumen therein for receiving an inner shaft. An inner shaft is movably carried within the lumen of the elongated catheter shaft. Extending distally from the distal end of the inner shaft is a tip. A retractable sheath extends proximally from the proximal end of the tip. The sheath, in an unretracted position covers the mounting region of the elongated catheter shaft. In use, once the catheter is in the desired bodily location, the inner shaft is moved in a distal direction relative to the elongated catheter shaft which causes the retractable sheath to be moved in a distal direction relative to the mounting region thereby exposing the stent for delivery.
