1. A method for attaching a split ring electrode to a tubing of a catheter, comprising:
- providing a tubing with at least one lumen, a side wall and at least one opening in the side wall providing communication between the at least one lumen and outside the tubing;
passing an electrode lead wire through the at least one lumen and out of the at least one opening to expose a distal portion of the electrode lead wire;
positioning the distal portion of the electrode lead wire on an outer surface of the tubing;
mounting a split ring electrode on the outer surface of the tubing covering the opening and the distal portion of electrode lead wire; and
providing an electrically-conductive adhesive between the ring electrode and the outer surface of the tubing.

Abstract
A method for attaching a split ring electrode to a catheter tip section includes providing a tubing with a lumen and an opening in the tubing side wall, passing an electrode lead wire through the opening, and wrapping the lead wire around the tubing. A split ring electrode is mounted on the tubing over the wrapped lead wire and opening, with electrically-conductive thermoplastic elastomeric adhesive applied between the ring electrode and the outer surface of the tubing, and reheated to reflow.
