Abstract: A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes one or more balloon pressurization steps. The balloon pressurization steps are selected to enhance scaffold retention to the balloon, maintain a relatively uniform arrangement of balloon folds about the inner surface of the crimped scaffold so that the scaffold expands in a uniform manner when the balloon is inflated, and to avoid any possible over-stretching of balloon material.

Abstract: Bioabsorbable polymer scaffolds with coatings are disclosed that include immobilized antithrombotic agents on the scaffolds or in or on the coatings. The agents act synergistically with antiproliferative agents released from coatings by providing hemocompatibility during and without interfering with antiproliferative agent release. Methods of modifying scaffolds and coatings with the antithrombotic agents are disclosed.
