Abstract
The invention relates to a device for HF-coagulation of biological tissues by means of flexible endoscopy. The invention includes a mobile applicator in a working channel of the endoscope catheter for supplying ionizable gas and containing a current supply connection line to an active mobile electrode at the distal end. According to the invention, the active electrode, relative to the distal end of the endoscope catheter, is movable into the said distal end for non-contact coagulation and out of it for contact coagulation. The respective position of the active electrode or electrode point is monitored by a sensor and, on the basis of a sensor signal upon reaching the retracted position of the electrode, a release takes place for igniting a plasma discharge.
