Abstract
Device for delivering radio frequency (RF) energy, for example during tissue ablation procedures, comprising an electrode having a distal end associated with tissue puncturing means and a proximal end connectable to a radio frequency energy source, wetting means for wetting the proximity of the distal end 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 a process for cooling and wetting a radio frequency energy delivering device and to a guidance element therefor.
Claims10
A device for delivering radio frequency (RF) energy, for example during tissue ablation procedures, comprising:
- an electrode having an uninsulated distal end and a proximal end connectable to a radio frequency energy source, and
- wetting means for wetting the distal end of the electrode and the proximity thereof with a non-toxic (RF) conductive solution wherein the wetting means comprise a first channel which defines a flow path for the wetting solution, wherein tissue puncturing means are associated either with the distal end of the electrode or with an inner axial slidable pith organ and wherein the device further comprises cooling means for cooling at least the distal end of the electrode, which cooling means comprise a second channel which defines a flow path for the cooling solution, wherein the wetting channel is open at the distal end of the electrode and wherein the cooling channel is closed at the distal end of the electrode, with the cooling channel and the wetting channel being mutually isolated.
