A splittable hemostatic valve (14) and introducer sheath (12) is provided for introductions of leads or catheters through the valve and sheath combination (10) into a vein or artery. Because of the hemostatic valve (14), this sheath (12) can remain in the vein throughout the operation with easier lead manipulation, especially in dual lead insertions, without bleeding, risk of air embo- lism or repeated sheath insertion related trauma. A side arm (18) to the hemostatic valve cage provides continuous fluid drip in order to prevent clot formation in the lumen of the sheath (12). At the point in the operation where the introducer sheath (12) and hemostatic valve (14) must be removed from the lead or catheter, score lines (36, 34) are employed to split or separate the introdu- cer sheath (12) and valve (14) a part so that the sheath (12) and valve (14) are removed from the implanted lead or catheter without sliding either the sheath (12) or valve (14) over the free end of the lead or catheter. The hemostatic valve is made in two separate parts (16a, 16b) which include a fluid-tight seal to facilitate splitting of the valve.
