Abstract
The present invention provides an improved stent delivery catheter. The stent delivery system comprises a catheter with a retractable sheath arranged concentrically near its distal end. The retractable sheath is connected to a pull wire for retraction. A sliding seal connects the proximal end of the retractable sheath and the catheter. This seal forms a fluid tight chamber when the retractable sheath is in the unretracted position, allowing the delivery system to be prepared by filling the fluid tight chamber with fluid to flush out air prior to insertion into the vasculature of the patient.
