Patent number: 7187442Abstract: A variably-polarizing optical probe assembly. The assembly includes an optical probe having one or more optical light delivery channels that emit incident light from the sample end of the probe toward a sample being investigated, and one or more optical light-receiving channels that receive incident light from the sample. A variably-polarizing substrate assembly is coupled to the sample end of the probe. The substrate assembly includes an optically transmitting substrate and one or more discrete polarizer areas on a face of the substrate, each such polarizer area defining a polarization orientation, with the polarizer areas together defining one or more different polarization orientations. The substrate assembly is arranged relative to the probe such that one polarizer area covers at least one light delivery channel and one polarizer area covers at least one light-receiving channel.Type: GrantFiled: April 30, 2004Date of Patent: March 6, 2007Assignee: Optimum Technologies, Inc.Inventors: Randal B. Chinnock, Jeffrey S. Melanson

Patent number: 7130047Abstract: Methods of creating tooling designs for, and the production of, one or more polarizer groups on a workpiece. Each such group includes an optically transmitting substrate with one or more discrete polarizer pixels thereon. The polarizer groups are used with optical instruments having a number of optical channels. In the method, one or more physical characteristics of at least one optical channel of the optical instrument are measured. Based on the determined physical characteristics, one or more discrete polarizer groups to be created on the substrate are defined, by defining for each such group a location on the substrate for the group, the size, shape and location within the group of each polarizer pixel of the group, and the polarization orientation for each such polarizer pixel of the group. The area of each polarizer pixel is then filled with tooling information that will establish its polarization orientation.Type: GrantFiled: October 7, 2005Date of Patent: October 31, 2006Assignee: Optimum Technologies, Inc.Inventors: Randal B. Chinnock, Jeffrey S. Melanson

Patent number: 6997871Abstract: An endoscope comprises a sheath, an articulation section adjacent to its distal tip, and two or more separate optical channels that produce two or more distinct views. Each of the optical channels comprises an objective lens and a means of capturing and/or viewing the image. The objective lens or lenses of the optical channel that produces the first distinct view, is located at a first location on the distal tip. The objective lens or lenses of the optical channel that produces the second distinct view is located at a second location on the proximal end of the articulation section or on the sheath of the endoscope adjacent to or located proximally of the articulation section.Type: GrantFiled: September 6, 2001Date of Patent: February 14, 2006Assignee: Medigus Ltd.Inventors: Elazar Sonnenschein, Minelu Sonnenschein, Randal B Chinnock

Patent number: 6835200Abstract: A method includes advancing an apparatus having an elongated member transorally into the stomach. The apparatus includes a distal end effector having first and second members configured to engage tissue. The first and second members are movable relatively toward one another generally in a first plane. The method includes moving the distal end effector relative to the elongated member in the first plane such that the distal end effector is retroflexed out of alignment with the elongated member to position the first and second members for engagement with the tissue. At least one of the first and second members carries a fixation device for fixing engaged portions of tissue together.Type: GrantFiled: July 18, 2002Date of Patent: December 28, 2004Assignee: ndo surgical. Inc.Inventors: Michael D. Laufer, Jeffrey C. Cerier, Amos Cruz, Jonathan O'Keefe, Richard Andrews, Vincent A. Puicci, Jr., Michael Barenboym, Neal H. Marshall, Randal B. Chinnock
