Method of manufacturing an elongated catheter having multiple sensors for three-dimensional location of the catheter

A flexible catheter includes an elongated body, a first monolithic wire, and a second monolithic wire. The first monolithic wire forms a first sensor that is disposed in the distal end portion of the elongated body. The first sensor is configured to detect the position of a distal end of the elongat...

Beschreibung
Zusammenfassung:	A flexible catheter includes an elongated body, a first monolithic wire, and a second monolithic wire. The first monolithic wire forms a first sensor that is disposed in the distal end portion of the elongated body. The first sensor is configured to detect the position of a distal end of the elongated body within anatomy of a patient. The second monolithic wire forms a second sensor that is disposed in the distal end portion of the elongated body a known distance from the first sensor. The first and second sensors are configured to determine the position of the distal end portion within six degrees-of-freedom. A method of manufacturing the flexible catheter is also provided.
