ABSTRACT:
The electrode catheter comprises a flexible spiral wound element accommodated coaxially within and extending the entire length of a first sheath such a way as to provide a core ensuring rigidity, for the purposes of the initial implantation, and flexibility to allow subsequent adaptation of the catheter to the subcutaneous cavity ultimately occupied. The spiral wound element carries a set of wires, each bared at the distal end, which break out of respective holes in the sheath to connect with relative terminals or sensors; each bared end is flattened against a corresponding first ring crimped coaxially to the sheath alongside the relative hole, and sandwiched between this same ring and a second ring of electrically conductive and biocompatible material by which the sensor or electrode is fully encapsulated.
