A medical probe is provided that has a single longitudinally uniform interconnect that provides a connection between a distal end and a proximal end of the probe. The interconnect is obtained by forming a thin uniform film as a spiral on a wafer and subsequently applying this spiral as a helix on a base element of a medical probe. The thin film spiral is manufactured with multiple connecting wires to enable connection between an electronics module and a multiplicity of electrodes (an electrode array) at the distal end of the medical probe.
