Original Abstract Submitted

An ablation catheter includes a tubular shaft having a proximal portion and a distal end and an electrode assembly extending from the distal end of the shaft. The electrode assembly includes a plurality of splines each having a spline proximal portion secured to the shaft, and an opposite spline distal portion. Each spline includes an electrically conductive support member partially disposed within an insulating member. The support member has a proximal end portion disposed within the insulating member and a distal end portion extending distally of the insulating member and terminating at a support member distal end. A plurality of sensing electrodes is disposed along each spline. A spline retainer mechanically engages with at least one of the proximal and distal portions of the splines.
