1. An intravesical drug delivery device comprising:
an elongated body having a first end, an opposed second end, and an intermediate portion between the first and second ends,
wherein the elongated body comprises:
a first lumen extending through the intermediate portion in a direction between the first and second ends and which contains a drug, and
a second lumen extending through the intermediate portion in a direction between the first and second ends and which contains a first silicone cured to bias the elongated body in a coiled retention shape, such that the device is elastically deformable between a relatively straightened shape suited for insertion of the device through a urethra and into the urinary bladder of a patient and the coiled retention shape which is suited to retain the device within the urinary bladder,
wherein the drug in the first lumen is in a matrix system in which the drug is dispersed in a flexible polymeric material, and the matrix system is in direct contact with an inner surface of a wall of the elongated body defining the first lumen, and
wherein drug release in vivo is controlled by diffusion of the drug from the matrix system and diffusion through the wall of the elongated body.
