Embodiment Construction

[0056]FIG. 1a shows a flexible application device 1 which is suitable for the high-frequency therapy of biological tissue. The application device 1 includes a connecting element 8, in the interior of which is disposed the electrical and mechanical interface between the cable 9 and the lines within the high-frequency catheter 5.

[0057]At its proximal end 10 the connecting element 8 has a through passage, through which a cable 9 is passed. The cable 9 is connected by way of the connection 20 to the supply and control unit 11 with which a high-frequency ac voltage can be generated in per se known manner.

[0058]At the distal end 7 of the connecting element 8 a flexible tubular high-frequency catheter 5 is passed through a suitable opening into the interior of the connecting element 8 and fixed there.

[0059]The high-frequency catheter 5 includes a shaft tube 6 with a lumen extending therethrough. The casing of the shaft tube 6 is formed from an elastic material, for example a polymer, in pa...

Abstract

The invention concerns a flexible application device including a tubular high-frequency catheter with a flexible shaft tube having at least one lumen passing therethrough, a head electrode arranged at the distal end of the catheter, an electric line with a connection for a generator ,and a connecting element arranged at the proximal end of the shaft tube between the shaft tube and the line. An electrically conducting traction element extends in the lumen between the head electrode and the connecting element and is fixedly connected to the head electrode on the one hand and the connecting element on the other hand in such a way and which is of such a tensile strength that all external forces which occur during a treatment and which act on the catheter can be transmitted to the connecting element by way of the head electrode and the traction element.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation application of U.S. patent application Ser. No. 11 / 920,400, filed Jan. 23, 2009, which is a 35 U.S.C. §371 national phase conversion of PCT / EP2006 / 061762, filed Apr. 21, 2006, which claims priority to German Patent Application No. 10 2005 023 303.1, filed May 13, 2005, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention concerns a flexible application device for the high-frequency therapy of biological tissue. The application device includes a tubular high-frequency catheter with a preferably flexible shaft tube which has at least one lumen therethrough and which fits to or in a connecting element, and at least one head electrode arranged at the distal end of the high-frequency catheter.[0003]In particular the invention concerns an application device for endoluminal or interstitial-endoscopic use.[0004]Application devices for high-frequency therapy are known.
