摘要
A medical device-includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention. A crimping temperature is maintained at about the onset of glass transition of the polymer material to facilitate more rapid stabilization of mechanical properties in the scaffold following crimping.
