Patent number: 9072445Abstract: A method and apparatus for imaging features of a CBD in a patient introduces a fluorescent contrast agent into the CBD. A light source transmits both a visible light and a fluorescent light into a patient's abdominal cavity via the laparoscope. Cameras attached to or integrated into the laparoscope detect visible light images and fluorescent emission light images. The visible light image and fluorescent image signals are processed to combine the fluorescent emission light image signals and visible image signals into a single display signal. The system adjusts the display characteristics, such as color, of the fluorescent emission light image so it contrasts well with the visual light image so the surgeon can easily distinguish between the two images. The display signal is sent to a video monitor where the surgeon views the visible light image and the fluorescent image as a single overlaid image.Type: GrantFiled: January 24, 2008Date of Patent: July 7, 2015Assignee: LIFEGUARD SURGICAL SYSTEMS INC.Inventors: Ramon Berguer, Michael Robert Gluszczak

Patent number: 9036140Abstract: An optical probe system having a probe with an optical guide (G) having a distal end. The optical guide (G) is mounted inside a housing (H) so that the distal end is displaceable with respect to the housing (H). A set of actuators (A), e.g. electromagnetic drive coils, can displace the distal end by application of a drive signal (Vx, Vy). A control unit (CU) generates the drive signal (Vx, Vy) so as to provide a scanning frequency which varies according to an amplitude of the drive signal (Vx, Vy). With such probe system it is possible to scan a field of view with a scanning frequency that varies with the scanning radius. Taking into account the maximum allowable drive current, it is possible to increase scanning speed compared to scanning at the mechanical resonance frequency of the optical system, since small radii can be scanned at a high scanning frequency.Type: GrantFiled: September 10, 2010Date of Patent: May 19, 2015Assignee: Koninklijke Philips N.V.Inventors: Nenad Mihajlovic, Jeroen Jan Lambertus Horikx, Waltherus Cornelis Jozef Bierhoff, Cornelius Antonius Hezemans, Bernardus Hendrikus Wilhelmus Hendriks

Patent number: 9028396Abstract: Broadband light and narrowband light are simultaneously projected toward a subject. The subject is imaged by a color CCD to obtain a blue signal, a green signal, and a green signal. A base image is generated from the signals of three colors.

Patent number: 8964110Abstract: In the imaging apparatus according to an aspect of the present invention, the aperture area ratio between the plurality of regions of the multifocal lens is appropriately configured. Thereby, it is configured such that, when a plurality of images are simultaneously imaged via the plurality of regions using the illumination light source, brightness of the image of the subject at an in-focus distance corresponding to one region of the plurality of regions, the image imaged via the one region, the brightness arising from the illumination light, is substantially equal to brightness of the image of another subject at an in-focus body distance corresponding to another region, the image imaged via the other region except the one region, the brightness arising from the illumination light. Accordingly, the subject at any of the distances does not suffer excess or deficient exposure.Type: GrantFiled: May 30, 2014Date of Patent: February 24, 2015Assignee: Fujifilm CorporationInventor: Shuji Ono

Patent number: 8956281Abstract: An in vivo endoscope illuminates tissue using multiple sources. Light from a short-range source exits a tubular wall of the endoscope through a first illumination region that overlaps an imaging region, and the light returns through the imaging region after reflection by tissue, to form an image in a camera. Light from a long-range source exits the tubular wall through a second illumination region that does not overlap the imaging region. The endoscope of some embodiments includes a mirror, and light from an emitter for the short-range source is split and reaches the first illumination region from both sides of an optical axis of the camera. Illuminating the first illumination region with split fractions of light results in greater uniformity of illumination, than illuminating directly with an un-split beam. The energy generated by each source is changed depending on distance of the tissue to be imaged.Type: GrantFiled: January 15, 2014Date of Patent: February 17, 2015Assignee: Capso Vision, Inc.Inventor: Gordon C.

Patent number: 8945001Abstract: A miniature ingestible capsule has multiple therapeutic or diagnostic operations that can be performed. These functions are controlled by a combination of an outside control, a pose beacon and through information relayed from an imagining array and transmitter. These functions can be in a separate capsule without an imaging array or within the same capsule with an imaging array. Typically, there is one function performed in addition to imaging. These functions can include suction and spray capabilities, ultrasound sensor, lithotripsy, laser, heat, electrocautery, BICAP, biopsy forceps, a needle knife snare cautery (cold and hot with continuous or pulsed current for cutting and coagulation), with a basket, and fine needle aspiration with various wheels and fins and motors controlled externally and other tools to be used in humans. All of these tools can be attached to a retractable arm. Also, they can be used on an elevator device that lifts them, allowing for an extra 180° of movement.Type: GrantFiled: November 2, 2009Date of Patent: February 3, 2015Inventors: Tarun Mullick, Ramgopal Nair, Sudhir K.
