The system comprises the endoscopic accessory with a working end to be placed at the distal end of the endoscope, a control sheath extending proximally external to the endoscope and a control handle joined to the proximal end of the control sheath. The control handle is slidably mounted to the exterior surface of the endoscope shaft and is configured to permit grasping of both the shaft and the handle. With the control handle and endoscope shaft grasped with one hand, the other hand of the user is left free to manipulate the endoscope distal tip controls. Additionally, the external arrangement of the control sheath leaves the working channel of the endoscope free for use of accessories or operations.Type: GrantFiled: April 18, 2007Date of Patent: May 18, 2010Assignee: C.R. Bard, Inc.Inventors: Christopher T. Zirps, Timothy R. Membrino, David J. Copeland, Sean J. Silva, Eric Mears, Joseph Logan, Stephen J. Yardan

Patent number: 7713189Abstract: A video endoscope includes a tube fitted at its distal end with an affixed objective lens, a video camera mounted behind the objective lens in the tube, the camera together with an elongated rotation element constituting a swivel unit that is supported both at the distal and proximal end zones in each case by swivel bearing at the tube. The swivel element being rotationally adjustable relative the tube by a swivel drive system. The distal swivel bearing is axially and radially bearing and the proximal swivel bearing is only radially bearing.Type: GrantFiled: September 7, 2005Date of Patent: May 11, 2010Assignee: Olympus Winter & IBE GmbHInventor: Harald Hanke

Publication number: 20100081877Abstract: An endoscopic overtube with articulating fingers extending from the distal end. The articulating fingers form an opening that may be expanded by a balloon. When positioned in a puncture site in a tissue wall, the articulating fingers dilate and enlarge the puncture site to allow for the body of the overtube to pass through the puncture site. In various embodiments, the fingers may further comprise cutting elements to assist in the dilation of the puncture site.Type: ApplicationFiled: October 1, 2008Publication date: April 1, 2010Applicant: Ethicon Endo-Surgery, Inc.Inventor: Omar J.

Patent number: 7678045Abstract: An endoscope observation optical system capable of improving the observation resolution of a mucous membrane of a living body is provided. The endoscope includes an observation optical system compatible with both standard visible-light observation and blood-vessel-enhancement observation, whose main component of a displayed image is an absorption peak of hemoglobin present in a waveband lower than 480 nm, wherein some longitudinal chromatic aberration remains in the endoscope observation optical system due to undercorrection at a wavelength of 415 nm, and wherein the focal position during blood-vessel-enhancement observation is set closer to a near point than the focal position during standard visible-light observation.Type: GrantFiled: November 14, 2005Date of Patent: March 16, 2010Assignee: Olympus CorporationInventor: Tsutomu Igarashi

Patent number: 7658711Abstract: An endoscope, comprising an elongated tubular shaft for introducing into a body of a patient, the shaft having a longitudinal axis and a distal end, and further having an opening the distal end. A light guide is arranged along the shaft and has a light-emitting distal end, the light-emitting distal end being arranged in the area of the opening of the shaft in order to radiate light from the opening.Type: GrantFiled: May 23, 2006Date of Patent: February 9, 2010Assignee: Karl Storz GmbH & Co. KGInventor: Eckart Klemm

Patent number: 7637866Abstract: An optical adaptor for endoscope according to the present invention includes, in an outer casing, a light emitter, serving as a light source for illumination, and two terminals connected to the positive and negative electrodes of the light emitters to be externally projected from the inside of the outer casing. The connection of a diode between the positive and negative electrodes of the light emitters prevents the static electricity from being applied to the light emitter.Type: GrantFiled: May 16, 2005Date of Patent: December 29, 2009Assignee: Olympus CorporationInventor: Mitsunobu Ono

Patent number: RE41807Abstract: A capsule endoscope is disclosed that includes means for illuminating an object, means for imaging the object, and a transparent cover having a center of curvature. The transparent cover covers the illumination means and the imaging means, and the imaging means includes an objective optical system and an image detecting element. The illumination means is positioned relative to the image detecting element, as viewed axially from the object side of the capsule endoscope, so that an area that is symmetrically positioned about the optical axis of the objective optical system from a light emitting area of the illumination means overlaps an area of the image detecting element, but does not overlap any areas of the image detecting element that are used for image detection.Type: GrantFiled: June 28, 2007Date of Patent: October 5, 2010Assignee: Olympus CorporationInventors: Takeshi Yokoi, Akira Hasegawa, Shinya Matsumoto, Takayuki Suzuki, Hidetake Segawa, Hironobu Takizawa
