Abstract:
1. A method, comprising: providing a catheter having proximal portion and a distal portion; coupling a sensor assembly to the distal portion of the catheter; and coupling a plurality of wires to the sensor assembly such that the plurality of wires extend from the distal portion of the catheter to the proximal portion of the catheter, 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, 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 sheath having an inner wall forming a space containing at least the first and second wire bundles of the plurality of wires; wherein the first wire bundle of the plurality of wires coupled to the sensor assembly consists of a pair of wires; wherein the second wire bundle consists of a pair of wires; wherein the plurality of wires coupled to the sensor assembly are further divided into a third wire bundle, wherein the wires in the third wire bundle are twisted together to reduce electromagnetic interference; wherein the third wire bundle consists of three wires.
