A DELIVERY APPARATUS FOR A SELF-EXPANDING STENT

摘要

A self-expanding stent delivery apparatus (10) having a reinforced sheath (14) for the safe, effective and accurate deployment of self-expanding stents (100). The sheath (14) is formed from an inner polymeric layer (62), an outer polymeric layer (70) and a reinforcement layer (64) sandwiched therebetween. The reinforcement layer (64) comprises flat metallic wire to provide the requisite radial and axial strength. In addition, flat wire reduces the profile of the device.
