FLEXIBLE APPLICATION DEVICE FOR THE HIGH-FREQUENCY TREATMENT OF BIOLOGICAL TISSUE
First Claim
1. A method for medical treatment of a body part of a patient by high frequency coagulation, comprising the steps of:
- a) introducing a counterpart electrode into a body of the patient, the counterpart electrode being configured for electrical association with a head electrode;
b) introducing a high-frequency element, having the head electrode configured for coagulation treatment, into proximity with the body part;
c) applying a high frequency ac voltage with the head electrode to the body part at a voltage sufficient to effect a coagulation thereof;
d) withdrawing the high frequency element from proximity with the body part with, if necessary, continued coagulation of a length of the body part by the high frequency ac voltage on the body part, for an extent, as needed for the medical treatment.

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.
