    摘要： Medical devices, methods of manufacturing medical devices, and systems comprising medical devices are provided. The device comprises a shaft having a major lumen sized to receive a second medical device and an electrode mounted thereon. The shaft includes an inner liner and outer layer. The method of manufacture includes forming a shaft by forming an inner liner and an outer layer by covering the inner liner with a polymeric material. The method further includes mounting an electrode onto the shaft of the device, and then heating and cooling the shaft. The system comprises a medical device having a shaft and an electrode mounted thereon. The shaft has a major lumen sized to receive another device. The system further comprises an electronic control unit configured to receive signals from the electrode and to determine a position of the electrode and/or monitor electrophysiological data.

    摘要： An intraurethral, Foley-type catheter shaft contains a microwave antenna capable of generating a cylindrically symmetrical thermal pattern, within which temperatures are capable of exceeding 45.degree. C. The antenna, which is positioned within the shaft, is surrounded by means within the shaft for absorbing thermal energy conducted by the tissue and asymmetrically absorbing electromagnetic energy emitted by the antenna--a greater amount of electromagnetic energy being absorbed on one side of the shafts. This asymmetrical absorption alters the thermal pattern generated by the microwave antenna, making it cylindrically asymmetrical, which effectively focuses microwave thermal therapy toward undesirous benign tumorous tissue growth of a prostate anterior and lateral to the urethra, and away from healthy tissue posterior to the urethra.
