Abstract
A peel-away introducer sheath includes a tube sheath having a splittable handle at its proximal end. A gas or liquid sealing valve or other fitting is secured to a proximal face of the handle and includes an axial passage typically having a diameter approximately equal to the lumen diameter of the sheath. The valve includes a threaded connector which is received in a counter bore formed in the handle. In this way, the sheath may be split apart leaving only the valve or other fitting in place on a catheter passing therethrough.
