Patent number: 7753249Abstract: 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.Type: GrantFiled: February 15, 2005Date of Patent: July 13, 2010Assignee: Medigus Ltd.Inventors: Minelu Sonnenschein, Elazar Sonnenschein, Amir Govrin

Publication number: 20090250501Abstract: The invention is a stapler device comprising an anvil and staple cartridge located in the distal tip of an endoscopic device. The staple cartridge is comprised of a fixed proximal portion and a moveable distal portion, which slides into said fixed portion. Means are provided for moving the anvil back and forth, such that the anvil pushes against the distal face of the staple cartridge thereby pushing the moveable portion of the staple cartridge into the fixed portion and causing the staples to be ejected from said staple cartridge passively without said staples moving. The stapler of the invention has two embodiments, a side fastening embodiment and a front fastening embodiment. The endoscopic device that comprises the stapler can be used to perform many different stapling tasks, e.g. closure of a hole in the wall of an internal organ.Type: ApplicationFiled: May 31, 2007Publication date: October 8, 2009Applicant: MEDIGUS LTD.Inventors: Elazar Sonnenschein, Amir Govrin

Patent number: 7530984Abstract: 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.Type: GrantFiled: June 5, 2006Date of Patent: May 12, 2009Assignee: Medigus Ltd.Inventors: Elazar Sonnenschein, Amir Govrin, Minelu Sonnenschein

Patent number: 7369176Abstract: The invention is an imager assembly for a miniature camera head. The assembly comprises an imaging sensor having conductive leads; an objective lens system placed on top of the sensor; circuitry, mounted beneath the imaging sensor, for driving the sensor and amplifying the electrical signals; and conductive wires electrically linking the internal components of the assembly and for linking the assembly to remote locations. The conductive leads are bent and the circuitry and conductive wires are arranged and mounted such that the dimensions in a plane parallel to the sensor plane of the camera head are approximately equal to or less than the dimensions in the plane of the sensor. The circuitry is capable of delivering signals produced by the imaging sensor for further processing and the components of the imager, except for the imaging surface of the sensor and the objective lens system, are encapsulated by an isolating material.Type: GrantFiled: July 31, 2003Date of Patent: May 6, 2008Assignee: Medigus Ltd.Inventors: Elazar Sonnenschein, Binyamin Maly, Boris Zarud, Palhaz Shimshilashvili

Patent number: 7344493Abstract: An endoscopic device includes ultrasonic emitters, receivers, and reflectors for the precise alignment of parts of an endoscope relative to each other. The methods for determining the relative position of two parts of the endoscope are based on measuring the distance between them based on the use of one or more transducers or arrays of transducers functioning as transmitters of ultrasonic signals and one or more transducers or arrays of transducers functioning as receivers of the ultrasonic signals. In preferred embodiments of the invention, at least one of the receivers is replaced by a reflector and at least one of the transmitters also functions as a receiver.Type: GrantFiled: December 31, 2001Date of Patent: March 18, 2008Assignee: Medigus Ltd.Inventors: Elazar Sonnenschein, Minelu Sonnenschein
