COOLED-WET ELECTRODE

摘要

The invention relates to device for delivering radio-frequency (RF) energy, for example during tissue ablation procedures, comprising an electrode (1) having a distal end (3) associated with tissue puncturing means and a proximal end (2) connectable to a radio frequency energy source, wetting means for wetting the proximaty of the distal end (3) of the electrode with a non-toxic (RF) conductive solution and cooling means for cooling at least the distal end of the electrode. The invention further relates (to the use of the device according to the invention and) to a process for cooling and wetting a radio frequency energy delivering device and to a guidance element therefor.
