    摘要: Methods and devices provide delivery of one or more therapeutic agents to a treatment site at or near an aneurysm, such as an abdominal aortic aneurysm (“AAA”). Methods typically include placing a device at or near the AAA and releasing one or more therapeutic agents from the device. This may also involve releasing multiple agents in sequential fashion. Examples of possible therapeutic agents include doxycycline, roxithromycin, tetracycline, tetracycline derivatives, and collagen promoting agents, such as propranolol. Devices used to deliver one or more therapeutic agents may include stents, grafts, stent grafts, balloons with perforations and/or needles, expandable wire baskets, drug-eluting capsules, or suitable combinations thereof. One embodiment includes a stent graft with a distally-extending skirt and an supra-renal anchor.

    摘要: An implantable pump system including an external driver. The implantable pump is driven by the external driver during normal operation but may also operate on a battery. The external driver is used to drive the pump with the mechanical energy of the impeller also being used to charge the battery. The external driver is also useful during emergency situations to directly drive the pump if the battery or internal coils should fail. The pump is also preferably implanted in a subpectoral location outside the patient's rib cage.
