  • Patent number: 5344435
    Abstract: A method for the treatment of the prostate gland which heats the tissues which would otherwise be surgically removed with a trans-urethral resection of the prostate. This method is accomplished by combining a radiating energy device integrated with a urinary drainage Foley type catheter, which is modified to provide cooling along the urethra surfaces. The radiating device also serves as a means to measure the tissue radiated thermal energy for the control or monitoring of temperature of the prostate tissues being heated. A urethral inserted applicator for prostate hyperthermia includes a multi-tube, balloon type catheter. The catheter includes a fluid dry tube for an energy radiator antenna applicator which also serves as a radiometric temperature sensor for measuring the temperature of the prostate tissue, and an open fluid receiving tube. An electromagnetic energy generator supplies electromagnetic energy to the applicator.

  • Patent number: 5249585
    Abstract: A urethral inserted applicator for prostate hyperthermia includes a multi-tube, balloon type catheter. The catheter includes first and second closed end fluid dry tubes, respectively, for a helical coil electrode type applicator, and an electromagnetic field compatible temperature sensor for measuring the temperature of the prostate tissue, and an open fluid receiving tube enabling urine drainage from the bladder. A radiofrequency source supplies electromagnetic energy to the applicator. A control unit contains a comparator which is connected to the temperature sensor and a temperature reference device for comparing the actual tissue temperature level with a desired temperature level and output control signals to the radiofrequency generator for controlling the output to the applicator. The coil type applicator is an elongated coil connected to the center conductor of a coaxial cable.

  • Patent number: 4967765
    Abstract: A urethral inserted applicator for prostate hyperthermia includes a multi-tube, balloon type catheter. The catheter includes first and second closed end fluid dry tubes, respectively, for a helical coil antenna type applicator, and a microwave type temperature sensor for measuring the temperature of the prostate tissue, and an open fluid receiving tube. A microwave generator supplies electromagnetic energy to the applicator. A comparator is connected to the temperature sensor and a temperature reference potentiometer for comparing the actual tissue temperature level with a desired temperature level and outputting control signals to the microwave generator for controlling the output to the applicator. The coil type applicator is an elongated coil having a tip end connected to the center conductor of a coaxial cable and an opposite end connected to the outer conductor of the coaxial cable.
