Abstract
A catheter assembly includes an elongated catheter shaft, a magnetic sensor, and one or more wires. The elongated catheter shaft has a shaft proximal end and a shaft distal end, and the magnetic sensor includes a coil having a coil proximal end and a coil distal end that is situated toward or at the shaft distal end. The one or more wires extend through the elongated catheter shaft and are situated adjacent the magnetic sensor. Each of the one or more wires is electrically coupled to the coil at the coil distal end.

A catheter assembly, comprising:
- an elongated catheter shaft having a shaft proximal end and a shaft distal end;
- a magnetic sensor including a coil having a coil proximal end and a coil distal end that is situated toward or at the shaft distal end;
- and
- one or more wires extending through the elongated catheter shaft and situated adjacent the magnetic sensor, the one or more wires electrically coupled to the coil at the coil distal end.
A catheter assembly, comprising:
- an elongated catheter shaft having a shaft proximal end and a shaft distal end;
- a magnetic sensor including a coil having a longitudinal axis from a coil proximal end to a coil distal end that is situated at the shaft distal end;
- and
- a pair of wires extending through the elongated catheter shaft, from the shaft proximal end to the shaft distal end, wherein each of the pair of wires has a straight portion that is adjacent the coil and parallel to the longitudinal axis of the coil along the length of the magnetic sensor, the pair of wires electrically coupled to the coil at the coil distal end.
A method of assembling a catheter assembly comprising:
- providing an elongated catheter shaft having a shaft proximal end and a shaft distal end;
- providing a magnetic sensor including a coil having a coil proximal end and a coil distal end that is situated toward the shaft distal end;
- positioning at least one of a pair of wires adjacent the magnetic sensor from the coil proximal end to the coil distal end;
- and
- electrically coupling the at least one of the pair of wires to the coil at the coil distal end.
