Patent ID: 8755908

Claim:
A conductive coil arrangement for electrode catheters for cardiac therapy, comprising: a multipolar conductive coil having a plurality of coradially interwoven, individual coil wires; and a contact zone in which at least one individual coil wire from the conductive coil is configured for connection to a contact element for electrical contacting, wherein the at least one individual coil wire to be contacted is routed outwardly out of the wire interconnection of the conductive coil with a radial direction component, wherein the remainder of the conductive coil is routed further centrally axially through the contact zone, wherein the conductive coil, which is routed further centrally axially through the contact zone, comprises an individual coil wire, and the remaining radially outwardly extending individual coil wires of the conductive coil are in the form of individual contact coils which are disposed axially parallel and are distributed equidistantly around the periphery, and wherein the individual coils have a smaller outer diameter (a) relative to the outer diameter (A) of the conductive coil.
