  • Publication number: 20090272785
    Abstract: 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.

  • Publication number: 20090250501
    Abstract: 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.

  • Patent number: 7530984
    Abstract: 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.

  • Patent number: 7369176
    Abstract: 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.

  • Patent number: 7344493
    Abstract: 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.

  • Publication number: 20080000941
    Abstract: 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.

  • Publication number: 20070182842
    Abstract: 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.
