Abstract:
1. An implantable medical device for controlled drug delivery, comprising: a device structure which comprises a device body having at least one drug reservoir lumen, the device structure being deformable between a retention shape and a low profile shape for deployment in the bladder of a patient; and a drug formulation positioned in the drug reservoir lumen, the drug formulation comprising at least one drug, wherein the device comprises a retention frame lumen having a retention frame therein, the retention frame operable to impart the retention shape, and wherein the retention frame comprises two or more wire segments connected by at least one degradable link, the at least one degradable link being located within the retention frame lumen and configured to degrade at a selected time in vivo to cause the retention frame to cease imparting the retention shape and thereby permit the device structure to assume the low profile shape suited for excretion from the bladder.
