Abstract
A method and apparatus are disclosed for simultaneously providing a plurality of probe response signals indicative of electrical activity at a respective plurality of locations in a patient. The apparatus comprises a rigid needle shaft element comprising a piercing tip and a substrate supporting a plurality of electrode tracks, secured to the needle shaft element and extending along the shaft element away from the piercing tip. Each electrode track extends from a sensing end region arranged for providing a respective probe response signal responsive to localised electrical activity, along the region of the substrate, to a respective bond pad connection region. Recording surface regions of the plurality of electrode tracks are spaced apart in a plurality of substantially linear spaced apart configurations along the substrate.
