Claim 17:
18. A method of manufacturing an electrophysiology (EP) catheter, the EP catheter including a catheter sheath and an end effector extending distally from the catheter sheath, the end effector including a cylindraceous nitinol member the method comprising:
forming at least one electrode or thermocouple on the cylindraceous nitinol member of the end effector by etching or vapor depositing a first three-dimensional structure of a first electrically-conductive material onto a first non-conductive planar material that is layered over the cylindraceous nitinol member, an outer surface of the cylindraceous nitinol member in direct contact with an inner surface of the first non-conductive planar material, an outer surface of the first non-conductive planar material in direct contact with an inner surface of the first electrically-conductive material of the first three-dimensional structure;
forming together as at least one single unitary structure one respective position sensor coil and one respective force sensor on the catheter sheath by etching or vapor depositing a second three-dimensional structure of a second electrically-conductive material onto a second non-conductive planar material that is layered over a thin film of nitinol, an outer surface of the thin film of nitinol in direct contact with an inner surface of the second non-conductive planar material, an inner surface of the thin film of nitinol in direct contact with an outer surface of the catheter sheath, an outer surface of the second non-conductive planar material in direct contact with an inner surface of the second electrically-conductive material of the second three-dimensional structure.
