ABSTRACT:
A medical device that contains (a) at least one polymeric release region that either contains crazing or which is adapted to undergo crazing as a result of stresses (e.g., mechanical, chemical or thermal) that are applied during the implantation or insertion of the medical device into a patient; and (b) and a therapeutic agent disposed beneath or within the polymeric release region.
