Medical devices, kits, and methods are provided for delivering a fluid containing a drug to a patient. Devices ( 102, 402, 702 ) include a housing ( 104, 404, 704 ) defining a lumen and an osmotically-driven piston ( 420 ) moveable within the lumen. The housing may be elastically deformable between a first shape suitable for insertion through a patient's urethra and a second shape suitable for retention of the device in the patient's bladder. |
