  • Patent number: 5344441
    Abstract: The invention discloses an antenna arrangement with a supply line in the form of a coaxial cable arrangement suitable for high frequencies, in particular for medical applications of heat in hollow parts of the body, an extrusion process for the production thereof, a dilatation catheter with the antenna arrangement and a procedure for a dilatation treatment. The coaxial cable arrangement comprises a continuous inner conductor, an insulator arranged cylindrically around the inner conductor, a shielding device applied around the insulator in a first section of the coaxial cable arrangement which begins at the proximal end of the coaxial cable arrangement, a second section beginning at the distal end of the first section of the coaxial cable arrangement and ending at the distal end of the coaxial cable arrangement, said second section serving as an antenna and being designed without an insulator or a shielding device around the continuous inner conductor.
