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.

Stent delivery system with coaxial catheter handle

This invention is directed to a member which is mounted on an elongated intraluminal device such as a catheter or a guidewire, preferably the proximal portion thereof, which releasably holds at least one turn of a coiled product. The coiled product may be the intraluminal device on which the fixture is mounted or it may be a separate product. In one embodiment of the invention, the turn holding member has a body and at least one flexible arm which holds a turn against the body of the fixture. In another embodiment of the invention, the holding member is a tubular element having a wall portion with a spirally shaped cutout through which a turn of coiled product can be advanced into the inner lumen or the tubular element.
