Claim:
1. A method for making a medical device, comprising: using a scaffold formed from a tube comprising a polymer, the scaffold having struts and an outer diameter, and the polymer is characterized by a glass transition temperature (Tg) having a lower limit (Tg-low); using a crimping device having a crimp head, crimping the scaffold to a balloon of a balloon catheter to cause the scaffold's polymer struts to become pressed into a surface of the balloon by the crimp head and causing balloon material to extend into spaces between the struts as an outer diameter of the scaffold is being reduced in size by the crimp head, the crimping including: wherein the scaffold is placed on the balloon such that when inflated a scaffold deployed diameter is at least 2.5 times higher than a crimped scaffold diameter.
