Alan D. LUCAS - Brookline MA, US

International Classification:

A61B 17/34
A61B 34/10
A61B 34/20
A61B 90/00
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.

International Classification:

A61B 1/06
A61B 1/00
A61B 1/015
A61B 1/05
A61B 1/018

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.
