Problems solved by technology

[0003] As a result of the movement of the distal region of the probe between the extended position and the pretensioned crimped position, an axial force is exerted on the connection between the electrode and the electrically insulating barrier to which it is attached, whereby loosening can occur
this is disadvantageous

Embodiment Construction

[0020] The probe 1 according to the invention has an outer metal tube 2 through which a two-channel plastic hose 3 is guided, which is located at the far end of the metal tube 2 with a curved pretensioned distal end 3.1. stick out. The hose 3 has an outer wall 3.2 with a circular cross-section and two pipes with a part-circular cross-section separated by a partition wall 3.3.

[0021] Probe head 4 is inserted into the distal end 3.1 of flexible pipe 3 ( figure 2 ), the probe head constitutes the distal part 1.1 of the probe 1 and is preferably connected materially to the hose 3, in Figure 4 In some embodiments the connections are in particular by bonding (for example with a silicone adhesive).

[0022] The probe head 4 has a partially spherically rounded end face 4 . 1 . The probe head 4 also has two electrodes 4.3 in the form of metal bodies, which are separated from one another by an insulating connecting strip 4.2 made of plastic. At its end facing away from the end f...

Abstract

The invention relates to a device for the sclerotherapy of tissue by means of a bipolar probe which comprises a distal end piece with two electrodes that are electrically insulated from each other by an electrically insulating piece. In order to make a device of the above type comprising a bipolar probe more reliable, the electrodes have mutually opposed recesses that are filled with an electrically insulating material.

Description

technical field [0001] The present invention relates to a device for sclerotherapy of tissue using a bipolar probe A device having a bipolar probe having a distal end piece with two electrodes electrically insulated from each other by an electrically insulated insulating connecting strip. Background technique [0002] Sclerotherapy, for example denervation, such as denervation of the facet joints, is performed on body tissue with the aid of a probe of this type. Bipolar probes have two electrodes through which a voltage difference is applied. In order to allow the distal end of the probe to be inserted flexibly and also to reach the region lying laterally in the axial direction of the probe body, the probe has an elastically flexible distal region. On the other hand, the probe is introduced into the body in such a way that the probe is mostly retracted into the shaft connected to the handle part, in which the distal region of the probe is elongated against a pretension in...
