Telemetrically controlled band for regulating functioning of a body organ or duct, and methods of making, implantation and use

Claims a can be the non-fluid pressure ring (22) and is control unit device and method, and can exhibit the non-fluid pressure ring (22) is around the cylindrical or the guide tube and a can be the control the shrinking to the cylindrical or the casing pipe; the peripheral control unit is embedded with the ring and control wherein operation. The comprising a constant outer diameter rigid back side is (30,38), and reducing not endure the phenomenon the flexible shrinking system (31,36). With a high precision and high efficiency energy mechanical transmission (35), the driver is telemetered said driving and controlling, wherein device nonmotile, of which the time of extending, so the ring of the diameter while. The driver claims a reversible shrinking saturation cylindrical or catheter, the shrinking degree of determining easily, can not be the radiograph imaging. Further claims a method for use and implanted.
