Abstract
An intracardiac electrical potential reference catheter includes a proximal shaft section in a distal flexible tip section. The flexible tip section shaped in a geometry suitable for performing intracardiac mapping and includes a plurality of electrode axially spaced-apart thereon. The shaft section is formed from a polymeric material and includes a reinforcement layer, typically a stainless steel braid. The flexible tip section is also formed from a polymeric material and is free from any braided reinforcement. A core wire is attached to a proximal housing on the catheter at one end and to a distal electrode tip at the other end. In this way, the torque is transmitted along the length of the catheter by both the reinforced shaft and separately by the core wire.
