Claim:
1. A drug delivery device for intravesical administration comprising: a body which comprises a hollow tube having an outer surface, an inner surface, and a reservoir defined within the hollow tube; a drug formulation, which comprises a drug, contained in the reservoir prior to intravesical insertion of the drug delivery device, the drug formulation being in a solid form; and a single aperture through a sidewall of the hollow tube, the aperture providing a passageway to release the drug from the drug delivery device, wherein the hollow tube is formed of an elastomeric material comprising a water permeable and non-resorbable polymer, and the body can be elastically deformed to permit intravesical insertion of the drug delivery device, wherein the device is configured to permit diffusion of water in vivo through the sidewall of the hollow tube to solubilize the drug in the reservoir and then to release the solubilized drug by osmotic pressure through the single aperture.
