Abstract: A catheter (10) configured to be inserted into a scoping device (12). The catheter comprises a body (30) having a distal end and a proximal end, and an insertion device (28). The body includes at least a first lumen extending between the distal end and the proximal end, the first lumen being configured to receive at least one of a guide wire (24), a camera (52), an ablation device (54) and a probe device (56). The insertion device is connected to the body at the proximal end and includes a first passage for receiving the guide wire and a second passage for receiving one of the camera, the ablation device and the probe device. Some other embodiments provide a catheter kit.

Abstract: An electrosurgical apparatus is provided having a rechargeable power source which may be charged wirelessly. The apparatus comprises an oscillator for generating electromagnetic (EM) energy (e.g. radiofrequency energy or microwave frequency energy); a controller operable to select an energy delivery profile for the oscillator; a feed structure for conveying the electromagnetic energy to an output; a rechargeable power source arranged to supply power to the oscillator; and a receiver circuit comprising an inductive coupler configured to wirelessly receive power from a transmitter and supply received power to the rechargeable power source. The selection of an energy delivery profile may involve switching the oscillator on or off in one example, or may comprise more complex operation such as the selection of a pulse profile in some embodiments.

Abstract: An antenna system for a transmitter, said antenna system comprising an array of antennas, said array being controllable to transmit a signal over part or all of a coverage area of said transmitter; an amplifier coupled to each antenna, said amplifier being arranged to receive one or more signals to be transmitted by the respective antenna; and a further amplifier connected to at least one of said antennas, said further amplifier arranged to receive a signal to be transmitted over substantially all of the coverage area of said transmitter.

Abstract: An antenna system for a transmitter comprising an array of antennas and control means. The antennas are arranged to transmit over all or part of the transmitters coverage area. The control means control the number of antennas that are used to transmit a signal in dependence on the width of the signal to be transmitted.

Abstract: A base transceiver station comprising a first part and a second part, said first part comprising a plurality of antennas and said second part being arranged to provide signals for transmission by said plurality of antennas, said first and second parts being connected by feeder means, said second part being arranged to provide a plurality of calibration signals to said first part, said first part comprising summing means for summing the calibration signals received at the first part and means for providing the summed calibration signals to said second part, said second part being arranged to process said summed calibration signals to determine correction values for application by said second part to signals for said plurality of antennas.
