Stabilizing Instrumentation for the Performing of Endoscopic Surgical Procedures

Abstract

Apparatus and methods are disclosed for percutaneously providing a stabilized platform for performing endoscopic surgery. The disclosed instrumentation includes an endoscope, a fixation catheter, a loop suture, and a rigid mount. A loop end of the loop suture is inserted into the gastrointestinal lumen through the fixation catheter and encompasses the endoscope positioned within the gastrointestinal lumen. The thread end of the loop suture remains external of the patient and is tautly connected to the rigid mount to provide the desired stability to the endoscope for the performance of an endo-surgical operation. Distal to the stabilizing assembly, the endoscope has articulated joints for positioning the distal end of the endoscope in close proximity to the surgical site, and includes manipulator arms which extend beyond the distal face of the endoscope to facilitate access to the surgical site.
