PROBLEM TO BE SOLVED: To provide a device for placement in a patient, for example, in a bladder, for controlled release of a drug over a long period of time. An intravesical drug delivery device (900) having an elongated first end, an opposite second end, and an intermediate portion between the first end and the second end. A first lumen 914 comprising a body, the elongate body extending through the intermediate portion in a direction between the first end and the second end and containing a drug； A linear shape extending through the intermediate portion in a direction between a first end and a second end, the device being suitable for insertion of the device into a bladder through a urethra of a patient. Hardened to bias the elongated body into the coil-shaped holding shape such that it is elastically deformable between the shape of the elongated body and the coil-shaped holding shape suitable for holding the device in the bladder. A second lumen 922 containing one silicone 928. [Selection diagram] Fig. 9【課題】長期間にわたる薬物の制御放出のために、患者内、例えば膀胱内に配置するためのデバイスを提供する。【解決手段】膀胱内薬物送達デバイス９００であって、第１の端部、反対の第２の端部、及び前記第１の端部と第２の端部との間の中間部分を有する細長本体を備え、前記細長本体は、前記第１の端部と第２の端部との間の方向に前記中間部分を通って延在し、薬物を含有する、第１のルーメン９１４と、前記第１の端部と第２の端部との間の方向に前記中間部分を通って延在し、前記デバイスが、患者の尿道を通って膀胱内への前記デバイスの挿入に適した直線型の形状と、前記膀胱内の前記デバイスの保持に適したコイル型保持形状との間で弾性変形可能であるように、前記細長本体を前記コイル型保持形状に付勢するように硬化される第１のシリコーン９２８を含有する、第２のルーメン９２２と、を備える。【選択図】図９
