Patent ID: 8335551

Claim:
A picafina device for measuring an electrical signal occurring in body cells, the device comprising: a generally cylindrical device body with a proximal extremity, a distal extremity, an inner lumen and an outer surface; an anchor at the distal extremity; a plurality of measuring electrode tips on the outer surface in fixed relative positions at the distal extremity and on the anchor; a single signal carrying wire running inside the lumen; a plurality of electrode tip connectors in the distal extremity, each connector for connecting one of the measuring electrode tips to the signal carrying wire; a plurality of on/off switches, each on/off switch associated with one of the measuring electrode tips for selecting the associated measuring electrode tip and connecting it to the signal wire; and a device connector at the proximal extremity to connect the signal carrying wire to additional wires outside the device body, the additional wires for connecting to a measuring and/or recording instrument; wherein the measuring electrode tips are configured to measure the voltage values at cells next to the respective tips.
