ABSTRACT:
An electrode-carrying catheter has elongate, flexible tubing defining a proximal end, a distal end, and an electrically insulative outer tubular layer intermediate the ends, the tubing including a flexible core and a flexible non-conductive core-covering layer of plastic about the core. A plurality of electrically conductive electrodes is disposed on the outer tubular layer. In order to conduct electrical signals between the proximal end and each of the electrodes, a longitudinally-spaced plurality of flexible electrically conductive wires are helically wound around and at least partially into the core-covering layer. The wound wires define a removed section beneath a segment of each of the electrodes to enable electrical contact between a respective one of the wound wires and a respective one of the electrodes. Each electrode is in the form of an electrically conductive flexible flat ribbon for providing electrical communication with a respective one of the wound wires. Each ribbon is electrically and physically joined to a respective one of the wound wires, and wrapped about and crimped onto the outer tubular layer.
