Claim:
1. An apparatus, comprising: a balloon catheter assembly having a distal end and a proximal end, the catheter including a scaffold comprising a polymer crimped to a balloon of the catheter at the catheter distal end; a sheath disposed over the scaffold, the sheath applying a radially inward force on the crimped scaffold to limit recoil of the scaffold, the sheath comprising: wherein the scaffold is crimped by way of plastic deformation of the scaffold to the balloon such that when the sheath is removed the scaffold retains substantially the same diameter it had when disposed within the sheath; and wherein a balloon material is disposed between struts of the scaffold to contribute to a retention force between the plastically deformed scaffold and a surface of the balloon to resist dislodgment of the scaffold from the balloon after the sheath is removed.
