AMPLIFIER INTERFACE FOR MULTI-ELECTRODE CATHETER

Abstract

Disclosed herein is a multi-electrode catheter system including an amplifier stage and an amplifier interface. The amplifier stage includes at least a first quantity of amplifier channels. The amplifier interface includes a first interface having at least the first quantity of interface channels. The amplifier channels are respectively electrically coupled to the interface channels. The amplifier interface includes a second interface having a second quantity of catheter channels, the second quantity being greater than the first quantity. The catheter channels are configured to be respectively electrically coupled to corresponding electrode leads of a multi-electrode catheter. The amplifier interface includes a switching matrix electrically coupled between the first interface and the second interface. The switching matrix is configured to selectively electrically couple a selected subset of catheter channels to respective interface channels of the first quantity of interface channels.
