REDUCING RECOIL IN PERIPHERALLY-IMPLANTED SCAFFOLDS

摘要

A peripherally implanted polymer scaffold having a high degree of recoil is worked to reduce recoil in the scaffold when initially deployed at a target lesion in the body. The scaffold is plastically deformed from a crimped state to an expanded state by a balloon catheter. The scaffold is contained within a sheath to prevent recoil up until the point of use. Before the scaffold is introduced to the body, the restraining sheath is removed from the scaffold.
