Patent number: 7392076Abstract: A two dimensional image is registered with mechanical axis data, and possibly other data, using a surgical navigation system. This provides the user with additional graphical information on a display screen as the procedure is performed. The mechanical axis data can be generated using an anatomical assessment.Type: GrantFiled: November 4, 2003Date of Patent: June 24, 2008Assignee: Stryker Leibinger GmbH & Co. KGInventor: José Luis Moctezuma de La Barrera

Patent number: 6416494Abstract: The present invention relates to catheter balloons for medical devices. In particular, the present invention provides biaxially oriented semi-compliant catheter balloons comprising acrylonitrile polymers, acrylonitrile copolymers, and acrylonitrile blends, and methods of making same. The catheter balloons provided herein exhibit relatively high tensile strength, controlled compliance, reduced tendency for pinholing, ease of coating with and of bonding to other compounds, as well as resistance to moisture.Type: GrantFiled: June 11, 1998Date of Patent: July 9, 2002Assignee: Infinity Extrusion & Engineering, Inc.Inventor: Douglas Wilkins

Patent number: 6330468Abstract: A reflectance pulse oximeter that determines oxygen saturation of hemoglobin using two sources of electromagnetic radiation in the green optical region, which provides the maximum reflectance pulsation spectrum. The use of green light allows placement of an oximetry probe at central body sites (e.g., wrist, thigh, abdomen, forehead, scalp, and back). Preferably, the two green light sources alternately emit light at 560 nm and 577 nm, respectively, which gives the biggest difference in hemoglobin extinction coefficients between deoxyhemoglobin, RHb, and oxyhemoglobin, HbO2.Type: GrantFiled: November 3, 1998Date of Patent: December 11, 2001Assignee: University of South FloridaInventor: John Edward Scharf

Patent number: 6047204Abstract: When storing, in a storage medium, diagnostic image information representing a diagnostic image which is displayed on an image display system and on the basis of which a diagnosis is made, information on the viewing condition of the diagnostic image displayed on the image display system used in making the diagnosis is stored in the storage medium together with the diagnostic image information. The information on the viewing condition of the diagnostic image includes at least one of the condition of the image processing which is additionally carried out when the diagnostic image used in making the diagnosis is displayed by the image displaying system, the displaying properties of the display system itself and the condition of environment in which the system stands.Type: GrantFiled: October 29, 1997Date of Patent: April 4, 2000Assignee: Fuji Photo Film Co., Ltd.Inventor: Eiji Ogawa

Patent number: 5931780Abstract: A computerized method and system for the radiographic analysis of bone structure and risk of future fracture with or without the measurement of bone mass. Techniques including texture analysis for use in quantitating the bone structure and risk of future fracture. The texture analysis of the bone structure incorporates directionality information, for example in terms of the angular dependence of the RMS variation and first moment of the power spectrum of a ROI in the bony region of interest. The system also includes using dual energy imaging in order to obtain measures of both bone mass and bone structure with one exam. Specific applications are given for the analysis of regions within the vertebral bodies on conventional spine radiographs. Techniques include novel features that characterize the power spectrum of the bone structure and allow extraction of directionality features with which to characterize the spatial distribution and thickness of the bone trabeculae.Type: GrantFiled: November 29, 1993Date of Patent: August 3, 1999Assignee: Arch Development CorporationInventors: Maryellen L. Giger, Kunio Doi

Patent number: RE36648Abstract: This invention relates generally to the field of Magnetic Resonance Imaging (MRI) systems for generating diagnostic images of a patient's internal organs and more particularly, this invention relates to improved MRI systems with decreased interference between the magnetic field used for producing diagnostic images and the magnetic fields generated by the electric motors used for driving the pistons of the contrast media injectors. Additionally, the system employs an improved communication link between an externally located system controller and the injection head control unit located within the electromagnetic isolation barrier which defines the magnetic imaging room.Type: GrantFiled: February 23, 1998Date of Patent: April 11, 2000Assignee: Medrad, Inc.Inventors: Arthur E. Uber, III, Seid Waddell, John Stulen, Jon E. Manley, Salvatore J. Dedola, Gordon C. Newell
