1. A flexible catheter comprising:
- an elongated body having a proximal end portion and a distal end portion, the elongated body defining a working channel therethrough;
a braid disposed within the elongated body and at least in part defining the working channel;
a sensor disposed in the distal end portion of the elongated body for detecting the position of a distal end of the elongated body within the anatomy of a patient, the sensor being formed from a wire forming a first layer of wraps disposed on an outer surface of the braid at the distal end portion, the wire including first and second leads that form a twisted pair proximal to the first layer of wraps and extending to a proximal end portion of the elongated body;
a handle assembly operably coupled to the proximal end portion of the elongated body, the handle assembly defining a slot and including a ring coupled to an outer surface of the handle assembly; and
a telescopic channel including a clip configured to slide along the slot defined by the handle assembly and engage the ring to removably couple the telescopic channel to the handle assembly.

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.

9. A catheter system comprising:
-
a flexible catheter including; an elongated body having a proximal end portion and a distal end portion, the elongated body defining a working channel therethrough; a braid disposed within the elongated body and at least in part defining the working channel; and a sensor disposed in the distal end portion of the elongated body for detecting the position of a distal end of the elongated body within the anatomy of a patient, the sensor being formed from a wire forming a first layer of wraps disposed on an outer surface of the braid at the distal end portion, the wire including first and second leads that form a twisted pair proximal to the first layer of wraps and extending to a proximal end portion of the elongated body; a handle disposed over the proximal end portion of the elongated body, the handle longitudinally and rotatably fixed to the flexible catheter, the handle including an adapter in electrical communication with the sensor, the handle defining a slot and including a ring coupled to an outer surface of the handle; and a telescopic channel disposed over a portion of the elongated body and including a clip configured to slide along the slot defined by the handle and engage the ring to removably couple a proximal portion of the telescopic channel to a distal portion of the handle. - View Dependent Claims (10)
