Abstract
An extensible polyp retrieval apparatus designed to be slidably disposed along the outer surface of an endoscope that is fully or partially inserted in the lumen of a patient using a “connect and push” polyp retrieval apparatus to reach the distal end of the inserted endoscope. The polyp retrieval apparatus comprises: a flexible cylindrical polymeric tube capable of being deployed from a few centimeters in mounted length on an endoscope to over 210 centimeters in total length when partially deployed or fully extended, respectively; a multiplicity of clamping fasteners permanently mounted to the flexible cylindrical polymeric tube; a movable snare like device that is designed as an cooperating component of the polyp retrieval system to enable the grasping and storage of polyps therein so as to avoid the complete removal of the endoscope from the lumen as is normal to remove a large polyp after cauterization or after a piecemeal polypectomy. This is performed before continuing the inspection and removal process. The apparatus that is the subject of this invention will greatly improve this process and result in fewer chances for damage or injury to the patient along with the attendant…
