Abstract: An apparatus includes a processing assembly, a plurality of field generators, and a patient tracking assembly. The patient tracking assembly includes a sensor assembly and a communication assembly. The sensor assembly includes a first body, a first sensor, and an electrical conduit. The first body selectively attaches to a patient. The first sensor is mounted to the first body and generates a signal in response to movement within an electromagnetic field. The communication assembly includes a second body and a cable. The second body rotates relative to the first body from a first rotational position to a second rotational position. The cable extends away from the second body. The cable communicates with the processing assembly. The electrical conduit couples the first sensor with the cable while the casing is in the first rotational position and the second rotational position.

Abstract: An apparatus includes a cannula and a grip portion. The cannula includes a first lumen extending from a proximal end to a distal end of the cannula. The grip portion is secured to the proximal end of the cannula. The grip portion includes a second lumen, a transversely oriented vent port, a suction port, and a guidewire port. The second lumen is in communication with the first lumen. The transversely oriented vent port is configured to communicate with the second lumen to thereby vent the second lumen to atmosphere. The suction port is configured to communicate with the second lumen to thereby communicate suction to the distal end of the cannula via the first lumen. The guidewire port is configured to receive a guidewire. The guidewire port is further configured to communicate with the second lumen to thereby provide a path for the guidewire to reach the first lumen.
