The coupling member is positioned at the distal end of the catheter shaft assembly and at the proximal end of the end effector. The coupling member includes a body having an exterior. The position sensor assembly includes at least one coil. The at least one coil is configured to generate a signal indicative of a position of the at least one coil in response to an alternating magnetic field. At least a portion of the position sensor assembly is positioned about the exterior of the coupling member such that the portion of the position sensor assembly positioned about the exterior of the coupling member is external to the coupling member.

A catheter system (100) for placement within a blood vessel (108) having a vessel wall (108A) for treating a treatment site (106) within or adjacent to the vessel wall (108A) within a body (107) of a patient (109) includes a system console (123), one or more energy guides (122A), and an optical connector assembly (251). The system console (123) includes an energy source (124) and a console connection aperture (148). The one or more energy guides (122A) are configured to receive energy from the energy source (124).

A pulmonary treatment catheter and handle system including a catheter assembly with insertion tube coupled to a handle assembly. The system is further removably coupleable to a delivery device, such as a flexible bronchoscope or endoscope, having a port for coupling the handle assembly thereto, and a working channel in communication with the port for delivering the catheter assembly through the delivery device and into a body lumen.
