    摘要: Apparatus for X-ray guided surgery, including a reference element (20), which is placed in contact with the body (32) of a subject. The element includes a plurality of fiducial marks (22a, 22b, 22c) and a first coordinate sensing device (24), in predetermined, fixed positions in the element (20). A surgical tool (36), having a distal end for insertion into the body (32), includes a second coordinate sensing device (40) fixed thereto. A fluoroscope (54) forms an X-ray image of the body, including the fiducial marks. A computer analyzes the image to determine the position of the reference element in the image, so as to find coordinates of the first coordinate sensing device relative to the image, and registers the position of the tool with the X-ray image by referring coordinates of the second coordinate sensing device to the known coordinates of the first position sensor.

    摘要: Gastric apparatus (18) is provided, including one or more sensors (70, 72, 74), adapted to generate respective sensor signals responsively to a gastrointestinal (GI) tract physiological parameter of a GI tract of a subject, and an implantable control unit (90), comprising a rechargeable battery and a first set of one or more transducers. The implantable control unit (90) is adapted to receive the sensor signals, using one or more of the transducers of the first set, and transmit data responsively to the sensor signals, using one or more of the transducers of the first set. An external control unit (200), including a power source and a second set of one or more transducers, is adapted to drive the power source to inductively transfer energy via one or more transducers of the second set, so as to recharge the battery, and receive the transmitted data, using one or more transducers of the second set.
