A catheter system that includes a catheter with a lumen and extends from a proximal end to a distal end of the catheter, the distal end of the catheter comprising an opening. The catheter system further includes an RF generator configured to produce an high radio frequencies. An electrode is disposed within a wall of the catheter at the distal end of the catheter. The electrode is configured to produce a high radio frequency electromagnetic field that is contained within the lumen of the catheter. A plurality of wires connects the RF generator to the electrode. The plurality of wires extend along the length of the catheter.
