摘要：
Methods, apparatuses and systems are described for deploying a stent into a body lumen. A stent delivery system may include a sheath with a partially-tubular first portion made from a first material and a second portion made from a second material that is adhered to the first portion to form a tubular body. In some cases, the first material may be chemically incompatible with the second material such that the adhesion between the first portion and second portion is free from cross-linked bonds. The stent delivery system may further include a guidewire lumen with a distal tip that may be slidably disposed within the sheath and a tubular stent disposed between the guidewire lumen and an inside surface of the sheath. The sheath may be formed by coextruding the first material and the second material to form a striped tubular body of the sheath.
