Abstract: A flexible catheter includes an elongated body, and a sensor. The elongated body has proximal and distal end portions and defines a working channel therethrough. The sensor is disposed in the distal end portion of the elongated body and is adapted for detecting the position of a distal end of the elongated body within the anatomy of a patient. The sensor is formed from a wire that forms a first layer of wraps about the distal end portion of the elongated body and that includes first and second leads that form a twisted pair proximal to the first layer of wraps. The twisted pair of the first and second leads extends to the proximal end portion of the elongated body.

Abstract: A method of manufacturing a flexible catheter with a locatable sensor includes non-rotatably coupling a spool with a wire to a first portion of a spool carrier, non-rotatably coupling the spool carrier to a catheter body, and rotating the spool carrier with the catheter body, thereby wrapping a portion of the wire about a distal end portion of the catheter body to form a wrapping layer.

Abstract: A method of manufacturing a flexible catheter with a locatable sensor includes simultaneously rotating first and second spools about a common axis, whereby first and second leads of a wire twist together to form a twisted pair of the wire, and rotating a catheter body about a longitudinal axis defined by the catheter body, whereby the twisted pair of the wire wraps about a proximal end portion of the catheter body.
