An introducer system featuring a sheath which is kink resistant. Such a sheath thereby permits the sheath to be dramatically bent while still allowing a lead to be introduced therethrough. The kink resistance is provided by a composite construction of the sheath. In particular the sheath has at least one integral reinforcing fiber. In the preferred embodiment the reinforcing fibers are provided in a braided configuration. The sheath preferably is constructed to be readily split using a slitter in a longitudinal direction and thus permits the sheath to be removed from the venous system without having to withdrawn the sheath over an end of the pacemaker lead. In an alternate embodiment the sheath is scored, including the reinforcing fibers, to thereby permit the sheath to be longitudinally split apart and removed from the venous system without having to withdrawn the sheath over an end of the pacemaker lead.
