Abstract
A splittable introducer sheath includes a tubular body portion formed from a first material and at least one stripe extending an entire length of the main body portion, the at least one stripe being formed form a second material. The first material is one of a medium-density polyethylene modified with a friction-reducing additive or high-density polyethylene (HDPE) modified with a friction-reducing additive. The second material is a thermoplastic elastomer modified with a siloxane additive. The sheath is dividable longitudinally along the at least one stripe.
