Abstract
Intravesical drug delivery devices are provided which may include an elongated body formed of a matrix system of a drug dispersed in a silicone, wherein the elongated body has a first end, an opposed second end, and an intermediate portion between the first and second ends, and wherein the silicone of the matrix system is 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.
