摘要：
In one aspect, the present invention provides therapeutic-agent-releasing medical devices which comprise at least one region of piezoelectric material. Therapeutic agent release is initiated or increased when the piezoelectric material is subjected to mechanical stress, which leads to the development of a voltage across the piezoelectric material. This voltage is used to initiate or increase therapeutic agent release.
