摘要:
The invention is a medical device comprising an insertion shaft having an articulation section located near its distal end. The medical device comprises one or more alignment systems to assist in bringing two portions of the insertion shaft that are located on opposite sides of the articulation section into alignment. The alignment systems are selected from the following: a) a mechanical system comprising one or more alignment pins or screws and two or more locking screws located in one of the portions and a corresponding number of funnels and receptacles into which the alignment pins and the locking screws can be inserted or advanced respectively located in the other of the portions; b) an ultrasound system comprising an ultrasound reflecting mirror having one or more steps located on one of the portions and a ultrasound transmitter/receiver located on the other of the portions; and c) an optical system comprising one or more light sources that emit light from one of the portions and an image sensor located on the other of the portions.

A surgical method of treating morbid obesity via bariatric procedures, carried out endoluminally and transluminally using endoscopic devices that are introduced through natural body openings without the necessity of creating any incisions in the abdominal wall.
摘要:
A stapling device for a surgical endoscopic device provided with at least one flexible portion, comprising a staple-firing portion and an anvil portion, wherein one of the staple firing portions and one of the anvil portions are located longitudinally displaced from one another along the longitudinal axis of the endoscopic device, with at least a part of said flexible portion between them. The parts of the stapling device are in correct working relationship when one or more alignment and/or locking pins or screws that are stored in one of the staple firing portions or one of the anvil portions are extended and engage and lock or screw into receptacles that have been provided on the other of the staple firing portion or of the anvil portion.

The invention is a method of lowering the gastroesophageal junction below the diaphragm of a patient with a hiatal hernia during the performance of surgical procedures performed via natural orifices. The method comprises applying positive pressure ventilation with positive end expiratory pressure (PEEP) to the patient.
摘要:
The invention is a stapling device comprised of an articulation section having a staple cartridge containing staples and parts of a staple-firing mechanism located at one end and an anvil portion located at the other end. The front surfaces of the anvil and the cartridge are curved. When the articulation section is bent the curved front surfaces of the anvil and the cartridge are brought opposite each other. As the distance between said curved surfaces is reduced, their curvature helps to correct transverse misalignment and to bring the anvil and the cartridge into the correct working relationship.

The invention is a reusable miniature camera head (10) that can be attached to and detached from an object. The camera head comprises: a housing (18), a lens system (12), a solid-state sensor (14), components of an electronic driver (16), and an internal electrical connector (20) located at the proximal end of the housing and having a plurality of sockets (22) or pins (110) on its external face. The object has an external connector (24) for receiving the camera head. The internal and external electrical connectors comprise a plurality of pins or sockets arranged in matching patterns on opposing faces thereby allowing the camera head to be attached to or disconnected by engaging the two connectors. In preferred embodiments of the invention, the object to which the camera head is attached is an endoscopic or laparoscopic device, the solid-state sensor is a Charge Coupled Device (CCD), and the housing does not contain a printed circuit board.

摘要:
The invention is a transgastric method for the endoscopic partial fundoplication for the treatment of gastroesophageal reflux disease (GERD). The method makes use of an articulated endoscope, which is introduced through the mouth and esophagus into the stomach of the patient. A cutting tool is introduced through the working channel of the endoscope to cut a hole in the wall of the stomach. The endoscope is pushed through the hole and a grabbing tool is introduced through the working channel and used to grab the tissue at a location on the outer surface of the stomach and move the grabbed tissue close to the esophagus. The grabbed tissue is then stapled to the esophagus using a stapling device that is an integral part of the endoscope. If desired, after stapling the endoscope can be rotated one or more times and the procedure repeated. After the selected portions of the stomach wall have been attached to the esophagus, the endoscope is withdrawn from the body of the patient and the hole in the stomach wall is closed, preferably by means of a dedicated endoscopic stapling device especially designed for the task of closing holes in tissue.
