Abstract of the Disclosure A splittable hemostatic valve and introducer sheath assembly for introducing a lead or catheter therethrough and into a vessel of a patient. The assembly provides a relatively fluid-tight seal so that the assembly can remain in the vessel of a patient throughout an entire surgical operation with the advantage of devices being exchanged therethrough without bleeding, risk of air embolism, or repeated sheath insertion related trauma associated with such exchanges. The assembly includes a splittable introducer sheath and a splittable hemostatic valve coupled to the introducer sheath arranged and configured to permit introduction of a lead or catheter therethrough. To remove the hemostatic valve or introducer sheath from the implanted lead or catheter, means for permitting removal are provided for splitting apart or peeling away the hemostatic valve and the introducer sheath without the necessity of sliding either the valve or the sheath over the free end of the lead or catheter. The removal means for the hemostatic valve include a pair of diametrically opposed score lines extending along the length of the valve body. The removal means for the introducer sheath comprise a pair of longitudinal tabs along with a folded-back portion extending toward the distal end of the tubular sheath structure. The hemostatic valve assembly further comprises an annular elastic band for maintaining a slit membrane in a closed position, which is positioned proximate the proximal end of the valve body. - 30 -
