Patent ID: 8734437

Claim:
A medical catheter comprising: an extruded elongate tubular member having a central longitudinal axis, the elongate tubular member including an annular wall having an inner surface and an outer surface; two or more electrically conductive pathways embedded within the annular wall of the elongate tubular member and extending parallel to the central longitudinal axis of the elongate tubular member from a proximal region of the elongate tubular member to a distal region of the elongate tubular member; wherein the annular wall of the elongate tubular member in which the two or more electrically conductive pathways are embedded is a single layer of polymeric material having a continuous molecular structure; wherein at least one of the two or more electrically conductive pathways are embedded within the annular wall of the elongate tubular member during an extrusion process; wherein at least one of the two or more electrically conductive pathways includes a first electrically conductive element configured to pass an electrical current distally along the tubular member and a second electrically conductive element configured to pass an electrical current proximally along the tubular member.
