Patent number: 8406839Abstract: The present invention provides a method of measuring the concentration of a compound and a value of oxygen saturation in the blood of a part of a subject. Also provided is a device for carrying out the disclosed method. The method relates to measuring the concentration of a compound and a value of oxygen saturation in the blood part of a subject, and correlating the measured concentration of the compound and/or the value of oxygen saturation in the blood to a specific clinical condition. The device comprises a polychromatic light source, a receptor, a detector, and a processing system comprising a calibration algorithm.Type: GrantFiled: March 3, 2006Date of Patent: March 26, 2013Assignee: Covidien LPInventors: Ashwani Kaushal, Duncan MacIntyre

Patent number: 7328052Abstract: The present invention provides an apparatus and a method for identifying the risk of a clinical condition in a human or animal by correlating Near Infrared (NIR) absorbance spectral data with one or several parameters including a concentration of one or more substances in the skin, a concentration of one or more substances in skin plus subdermal tissue, a score derived from one or more clinical tests like a stress test on a treadmill, coronary angiography, or intravascular coronary ultrasound. The method determines the concentration of a compound in the skin of a human or animal and comprises the steps of placing a part of the skin against a receptor, directing electromagnetic radiation (EMR) from the near-infrared spectrum onto the skin, measuring a quantity of EMR reflected by, or transmitted through, the skin with a detector; and performing a quantitative mathematical analysis of the quantity of EMR to determine the concentration of the compound, for example free and esterfied cholesterol.Type: GrantFiled: September 17, 2004Date of Patent: February 5, 2008Assignee: NIR Diagnostics Inc.Inventors: James Samsoondar, Duncan MacIntyre, Ashwani Kaushal

Patent number: 6917422Abstract: The present invention provides a photometric reference member comprising PTFE and glass. The member exhibits an absorbance change of less than 0.0001 absorbance units per degree C. over a range of temperatures, preferably from about 20° C. to about 40° C., and over wavelengths from about 600 nm to about 1650 nm, preferably about 600 nm to about 1050 nm. The invention also pertains to methods of using the photometric reference member to correct for temperature variations or drift in absorbance measurements.Type: GrantFiled: January 22, 2003Date of Patent: July 12, 2005Assignee: NIR Diagnostics Inc.Inventors: James Samsoondar, Ashwani Kaushal

Patent number: 6912049Abstract: The present invention provides a thermally stable reference member comprising, at least one radiation attenuating element and at least one radiation scattering element. The radiation attenuating element comprising at least one aperture for transmission of radiation therethrough. The attenuating and scattering elements placed in series so that radiation transmitted through the reference member passes through each of the attenuating and scattering elements. The attenuating and scattering elements of the reference member may further comprise a thermally stable mount to hold the elements in a selected position relative to each other, and in relation to an instrument, or the elements may be bonded together.Type: GrantFiled: December 18, 2002Date of Patent: June 28, 2005Assignee: NIR Diagnostics, Inc.Inventors: Romuald Pawluczyk, Theodore Cadell, Bronislaw Bednarz, Ashwani Kaushal
