Abstract
Post deployment radial force recovery of biodegradable scaffolds are described where a high molecular weight polymer may be formed into a high molecular weight scaffold by solution casting into a tubular substrate such that the scaffold retains its mechanical properties through processing. The tubular substrate is laser cut and subsequently crimped onto a catheter for deployment into a body lumen. The polymeric scaffold may retain its mechanical properties and result in increased radial strength post-deployment in a saline environment, e.g., within a body lumen. This scaffold enhancement may be attributable at least in part to entanglement of high molecular weight polymer chains as one factor that effects radial force recovery and also to the design or geometry of the scaffold as another factor that effects radial force recovery after deployment.
