Abstract: A system for tracking the location of an anatomical structure, the system comprising: a J-bar and electrical lead assembly comprising: a J-bar comprising a tracker, a distal electrical connector formed on the tracker, and at least one mount for mounting the tracker to tissue, wherein the tracker is configured to provide a signal representative of the position of the tracker when the tracker is supplied with electrical power; an expandable basket configured to assume (i) a radially-reduced profile when the expandable basket is radially constricted, and (ii) a radially-expanded profile when the expandable basket is not radially constricted, the expandable basket further comprising a distal electrical connector; and an electrical lead extending distally between the J-bar and the expandable basket, the electrical lead being electrically connected to (i) the distal electrical connector formed on the tracker, and (ii) the distal electrical connector of the expandable basket.

Abstract: Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit inside of or next to the tissue mass. The system also includes a second sensor attached to a surgical instrument configured to measure the position and orientation of the surgical instrument. A controller is in communication with the first sensor and the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.

Abstract: A coupling cartridge and end cap for protecting an endoscope from contamination during use. The coupling cartridge provides fluid communication between a pair of external fluid conduits and respective channels formed in an endoscope insertion tube, and between a biopsy channel port projecting from the cartridge and an additional insertion tube channel. In one embodiment, fluid flow through the external fluid conduits is controlled by an external fluid control unit that is electrically controlled by respective switches mounted on the control handle of the endoscope. In another embodiment, fluid flow through the external fluid conduits is controlled by a valve mechanism in the coupling cartridge that is controlled by either an actuator on the cartridge or an actuator on the control handle that is mechanically coupled to the valve mechanism. The coupling cartridge may be removed from endoscope after an endoscopic procedure for disposal or rigorous cleaning.
