Patent number: 9033867Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and a motorized or powerable frame The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid. The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment. The motion of the toroid can be powered or unpowered and the direction and speed may be controlled.Type: GrantFiled: July 5, 2007Date of Patent: May 19, 2015Assignee: FUJIFILM CorporationInventors: Troy J. Ziegler, Timothy P. Sheridan, William T. Ryder

Patent number: 8062225Abstract: An immersion bag system for use with an ultrasound probe to overcome near field artifact including a flexible thin wall thickness immersion bag with an attached flexible collar having an integral internal seal. The immersion bag contains a gel or other ultrasound transmission medium and is sealingly and removably attached by a mutually formed probe/seal valve to the tip end of an ultrasound probe. The immersion bag is able to conform to a cornea, as well as to other surfaces, whether flat or irregular, thereby enabling an ultrasound probe to be used easily on such surfaces. An ultrasound probe, in use with the immersion bag system, is maintained at a distance above the contact surface of the immersion bag and is positionable about the vertical axis while the immersion bag maintains stationary conformal contact with the structure against which it is in contact.Type: GrantFiled: April 12, 2011Date of Patent: November 22, 2011Assignee: ESI, Inc.Inventors: Thomas C. Prager, Thomas A. Burba, David R. Hardten, William T. Ryder

Patent number: 7520845Abstract: A selector of a selectorized dumbbell comprises a keyboard having a plurality of keys that can be depressed into a weight selecting position. In this weight selecting position, a cam actuator on each key forces a pair of connecting pins apart to couple a particular weight to the handle. Preferably, to minimize the risk of accidental weight detachment from the handle, a pair of keys and two pairs of connecting pins couple each weight to the handle in a redundant fashion. The pins in each pair slide apart from one another to couple a weight to the handle and slide towards one another to uncouple a weight from the handle with the sliding motion of the pins being perpendicular to the axis of a hand grip of the handle.Type: GrantFiled: August 2, 2006Date of Patent: April 21, 2009Assignee: Intellex, Inc.Inventors: Carl K. Towley, III, Gregory S. Olson, William T. Ryder

Publication number: 20080032874Abstract: A selectorized dumbbell has a selector for coupling a desired number of weights from an array of nested weights to the handle of the dumbbell to select or determine the exercise mass of the dumbbell. The selector comprises a keyboard having a plurality of keys that can be depressed into a weight selecting position. In this weight selecting position, a cam actuator on each key forces a pair of connecting pins apart to couple a particular weight to the handle. A separate weight selection key is provided for each pair of connecting pins. At least one pair of connecting pins is provided for individually coupling each weight to the handle. Preferably, to minimize the risk of accidental weight detachment from the handle, a pair of keys and two pairs of connecting pins couple each weight to the handle in a redundant fashion.Type: ApplicationFiled: August 2, 2006Publication date: February 7, 2008Inventors: Carl K.
