Abstract:
1. A method of crimping, comprising the steps of: providing a scaffold formed from a tube comprising Poly(L-lactide) and characterized by a glass transition temperature range having a lower limit of TG-low, the scaffold having a network of interconnected scaffold elements comprising crown angles of between 90 and 115 degrees, crimping the scaffold to a balloon catheter at a crimping temperature of about 5 to 15 degrees below TG-low, the scaffold having a pre-crimp diameter and a final crimp diameter, including the steps of wherein the scaffold as an expanded diameter when the balloon is inflated to a nominal balloon diameter, and wherein the scaffold has a crush recovery of greater than 80% of the expanded diameter when crushed by an amount equal to 50% of the expanded diameter.
