US Patent:

55185010, May 21, 1996

Filed:

Dec 20, 1994

Appl. No.:

8/360235

Inventors:

Katsumi Oneda - Alpine NJ
Isao Fujimoto - Cresskill NJ
Alan D. Lucas - Boston MA

Assignee:

Vision-Sciences, Inc. - Natick MA

International Classification:

A61B 100

US Classification:

600127

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. The end cap fits onto the distal end of the insertion tube to isolate it from external contamination.

Alan D. LUCAS - Brookline MA, US

International Classification:

A61B 17/34

A61B 17/068
A61B 17/32

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:

In some embodiments, endoscopy systems and/or methods of using endoscopy systems are described. In some embodiments, an endoscopy system comprises a shaft having an image sensor within a distal tip of the shaft. The shaft can have an expandable cuff disposed on an outer surface of the shaft. The expandable cuff can be moved from a contracted configuration to a deployed configuration. In the deployed configuration, an outer surface of the expandable cuff can inhibit, reduce, or prevent fluid (e.g., blood) flow in the vessel. Inhibiting or preventing the fluid flow can permit direct visualization of the interior of the vessel by the image sensor without interference from the fluid.
