Patent ID: 8162856

Claim:
A sensor catheter, comprising: a catheter having proximal and distal ends, a proximal end of the catheter adapted to be coupled to a processing unit; a sensor assembly disposed at the distal end of the catheter; and a plurality of wires extending from the proximal end of the catheter to the distal end of the catheter, the plurality of wires coupled to the sensor assembly, wherein the plurality of wires are divided into at least first and second wire bundles, each of the wires in at least the first and second wire bundles twisted together such that the wires in at least the first and second wire bundles are not arranged side by side in order to reduce electromagnetic interference between the wires, and wherein the plurality of wires carry control signals transmitted to the sensor assembly and sensor signals transmitted from the sensor assembly; and wherein at least the first and second wire bundles are twisted together and disposed within an outer conductor assembly sheath having an inner wall forming a space containing at least the first and second wire bundles of the plurality of wires.
