Abstract
A basket-type EP catheter is described. The EP catheter comprises a catheter proximal end that is electrically connected to a controller by an electrical cable having a single voltage-out (Vout) conductor and a catheter distal end supporting a distal connector that is detachably connectable to a basket-shaped configuration of a plurality of splines. Each spline supports an array of electrodes. By sampling the voltage signal on each of the plurality of electrodes sequentially or consecutively, only one Vout conductor is needed to transmit the voltage sample to the controller. In comparison to conventional EP catheters, this greatly reduces the number of conductors extending along the catheter shaft. The use of a Vout conductor is implemented by connecting a polling circuit or a 'one-shot' circuit and a signal pass-transistor or transmission gate to each electrode.
