摘要：
In an example, an electrode array for selective electrical sensing in patient tissue is described. The electrode array comprises an elongate base and a plurality of elongate fingers. Each finger is attached to and extends longitudinally from a distal end of the base. When at least a portion of the electrode array is in a spatulate use configuration, each finger terminates in a free end spaced longitudinally from the base and spaced laterally apart from adjacent free ends of other fingers. A plurality of electrode pairs is distributed along a contact surface of each finger. Respective electrodes in each of the electrode pairs of each finger are spaced from one another. The electrode pairs of each finger are both longitudinally and laterally spaced from electrode pairs of adjacent fingers when in the spatulate use configuration. An example method of selectively sensing electrical activity at a target body tissue is described.
