Abstract
A stent delivery catheter handle for providing relative motion between the outer sheath of a stent delivery catheter and an underlying catheter, via a thumbswitch, to enable the outer sheath to withdraw from over the underlying catheter and expose a vascular prosthesis. The handle allows the annulus between the outer sheath and the underlying catheter to be filled with a purging fluid, to prevent blood from a patient's vascular system from entering the annulus and coagulating. A flush port forms a dynamic seal in the catheter handle.
