    摘要： An incontinence electrode for controlling urinary incontinence in women is made of alternating bands of conductive and non-conductive polymers molded to form a tubular body. Electrical receptacles, formed in the molding process at the interior circumferential surface of the conductive polymer bands, accept metal contacts attached to electrical leads to make a secure and durable, mechanical and electrical connection between the conductive polymer bands and the leads. The leads are coupled to a controller and carry electrical current to and from the metal contacts which then distribute the current to the conductive polymer bands to cause a contraction of the vaginal muscles responsive for controlling urinary incontinence in women.

    摘要： A catheter shaft carries a coaxial cable, the terminal end of which contains a dipole antenna with opposing first and second helical elements. The first and second helical elements originate from a common connection to an outer conductor of the coaxial cable. The first and second helical elements are formed by winding flat wire around an outer insulator of the coaxial cable near a terminal end of the coaxial cable. A tubular-shaped capacitor is connected between an inner conductor of the coaxial cable and a point on the second helical element where the resistive component of the antenna's impedance matches the characteristic impedance of the coaxial cable. This match minimizes reflective losses of the antenna, thereby maximizing power transfer to the antenna. The antenna has an effective electrical length which is equal to one half the wavelength of the radiation emitted, independent of the physical length of the antenna. The antenna also has a radiation length which can be adjusted by varying the number and pitch of turns of the flat wire and the location of the impedance matching point.
