METHODS AND APPARATUS FOR OFF-AXIS VISUALIZATION
First Claim
1. A surgical method, comprising:
- advancing an imager at a distal end of an endoscope through an elongate body until the imager moves out of the elongate body through a front end opening at a distal end of the elongate body;
positioning the imager at a first position to obtain a first field of view of a surgical site;
partially withdrawing the endoscope proximally until the imager is adjacent to or proximal of a skive opening through a sidewall of the elongate body;
re-advancing the endoscope to move the imager through the skive opening and into a second position outside of the elongate body, to obtain a second field of view of the surgical site, with the second field of view different from the first field of view.

Abstract
Methods and apparatus for off-axis visualization are described herein. An endoluminal tissue manipulation assembly is disclosed which provides for a stable endoluminal platform and which also provides for effective triangulation of tools. Such an apparatus may comprise an optionally shape-lockable elongate body defining a longitudinal axis and adapted for endoluminal advancement in a patient body, at least one articulatable visualization lumen disposed near or at a distal region of the elongate body, the at least one articulating visualization lumen being adapted to articulate off-axis relative to a longitudinal axis of the elongate body, and at least one articulatable tool arm member disposed near or at the distal region of the elongate body, the at least one articulatable tool arm member being adapted to articulate off-axis and manipulate a tissue region of interest.

9. An endoluminal surgical method, comprising:
-
advancing an imager on a front end of an endoscope through an elongate body; moving the imager out of a front end of the elongate body and into a first viewing position to provide a first field of view of a surgical site; pulling the endoscope back from the front end of the elongate body; steering the front end of the endoscope in an at least partially radially outward direction from a central axis of the elongate body; advancing the front end of the endoscope through a skive opening in a sidewall of the elongate body, and steering the endoscope to move the imager to a second viewing position to provide a second field of view of the surgical site, with the second field of view different from the first field of view. - View Dependent Claims (10, 11, 12, 13, 14, 15)
