Patent number: 7653429Abstract: Techniques for detecting fluorescence emitted by molecular constituents in a wall of a body lumen include introducing an autonomous solid support into the body lumen. Cells in a lumen wall of the body lumen are illuminated by a light source mounted to the solid support with a wavelength that excites a particular fluorescent signal. A detector mounted to the solid support detects whether illuminated cells emit the particular fluorescent signal. If the particular fluorescent signal is detected from the illuminated cells, then intensity or position in the lumen wall of the detected fluorescent signal, or both, is determined. These techniques allow the information collected by the capsule to support diagnosis and therapy of GI cancer and other intestinal pathologies and syndromes. For example, these techniques allow diagnostic imaging using endogenous and exogenous fluoroprobes, treating diseased sites by targeted release of drug with or without photoactivation, and determining therapeutic efficacy.Type: GrantFiled: October 16, 2008Date of Patent: January 26, 2010Assignee: The Johns Hopkins UniversityInventors: Igal Madar, John C.

Patent number: 6508759Abstract: A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity, wherein the eyepiece and the lens means are configured to facilitate stereoscopic viewing. In a variation of the surgical microscope, a plurality of binocular eyepieces are attached to the microscope body to allow multiple persons to contemporaneously view the magnified object image.Type: GrantFiled: October 28, 1999Date of Patent: January 21, 2003Assignee: Heartport, Inc.Inventors: Charles S. Taylor, Brian S. Donlon, Timothy R. Machold

Patent number: 6361491Abstract: An optical adaptor for an endoscope enabling an optically highly precise arrangement consists of a first frame member, a second frame member, and a distance restriction member. The first frame member is located at the distal part of the optical adaptor. A plurality of objective optical systems is stowed and held in the first frame member. The second frame member is located behind the plurality of objective optical systems. A relay optical system that transmits optical images formed by the objective optical systems and teams with an imaging optical system located in front of an imaging device in an endoscope to form an image transmission optical system is stowed and held in the second frame member. The distance restriction member is interposed between the first frame member and second frame member and thus sets the distance between the members to a predetermined value.Type: GrantFiled: December 13, 1999Date of Patent: March 26, 2002Assignee: Olympus Optical Co., Ltd.Inventors: Hiroshi Hasegawa, Hirofumi Miyanaga, Masahiro Chiba

Patent number: 6301043Abstract: An endoscope having a distally disposed lens and an optical transmission system which transmits the image of the lens to the proximal end of the endoscope is provided. The transmission system includes at least one reversing system, which includes two elements in mutual mirror-inverted arrangement. Each element includes a rod lens with planar faces and at least one optically thin lens having a planar surface. The rod lenses consist of an inhomogeneous material having a positive dispersion and an inhomogeneous refractive index in the radial direction, while the thin lenses are plano-convex lenses.Type: GrantFiled: December 31, 1998Date of Patent: October 9, 2001Assignee: Karl Storz GmbH & Co.
