Patent number: 8764680Abstract: A biopsy device includes a body, a needle, and a cutter. A motor is operable to both move the cutter relative to the needle and actuate a needle firing assembly to retract and fire the needle relative to the body. The biopsy device also includes a needle rotation assembly that is configured to substantially prevent rotation of the needle about the longitudinal axis when the needle is in a proximal position yet permit rotation of the needle about the longitudinal axis when the needle is in a distal position. A valve assembly of the biopsy device includes a slider that selectively couples a secondary lumen in the needle with either atmospheric air or saline based on the longitudinal position of the slider. The cutter passes through the slider.Type: GrantFiled: November 24, 2010Date of Patent: July 1, 2014Assignee: Devicor Medical Products, Inc.Inventors: Edward A. Rhad, John A. Hibner, Harold W.

Patent number: 8768424Abstract: A photoplethysmograph device includes a light source for illuminating a target object. A modulator drives the light source such that the output intensity varies as a function of a modulation signal at a modulation frequency. A detector receives light from the target object and generates an electrical output as a function of the intensity of received light. A demodulator with a local oscillator receives the detector output and produces a demodulated output, insensitive to any phase difference between the modulation signal and the oscillator, indicative of blood volume as a function of time and/or blood composition. A number of demodulators may be provided to derive signals from multiple light sources of different wavelengths, or from an array of detectors. The plethysmograph may operate in a transmission mode or a reflectance mode. When in a reflectance mode, the device may use the green part of the optical spectrum and may use polarizing filters.Type: GrantFiled: April 11, 2007Date of Patent: July 1, 2014Assignee: The University of NottinghamInventors: John Crowe, Mark Grubb, Barrie Hayes-Gill, Nicholas Miles

Patent number: 8764679Abstract: A disposable tissue removal device comprises a “tube within a tube” cutting element mounted to a handpiece. The inner cannula of the cutting element defines an inner lumen and terminates in an inwardly beveled, razor-sharp cutting edge. The inner cannula is driven by both a rotary motor and a reciprocating motor. At the end of its stroke, the inner cannula makes contact with the cutting board to completely sever the tissue. An aspiration vacuum is applied to the inner lumen to aspirate excised tissue through the inner cannula and into a collection trap that is removably mounted to the handpiece. The rotary and reciprocating motors are hydraulically powered through a foot pedal operated hydraulic circuit. The entire biopsy device is configured to be disposable. In one embodiment, the cutting element includes a cannula hub that can be connected to a fluid source, such as a valve-controlled saline bag.Type: GrantFiled: August 5, 2013Date of Patent: July 1, 2014Assignee: Suros Surgical Systems, Inc.Inventors: Michael E.

Patent number: 8753287Abstract: A hearing test method and apparatus are provided for improving a measuring accuracy and a test speed in finding the auditory threshold that is the audibility limit of discriminating a sound. In the method, after outputting a test sound relevant to a selected test frequency and a selected test sound pressure, the apparatus determines whether a user hears the test sound, then the test sound pressure zone is divided into an auditory threshold presence region and an auditory threshold absence region according to the result of determination. Thereafter, the test sound pressure zone is redefined using the auditory threshold presence region and this process of hearing test is repeated using the redefined test sound pressure zone to finally determine an auditory threshold for the selected test frequency.Type: GrantFiled: May 18, 2011Date of Patent: June 17, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Kyoung Ho Bang, Sang Ki Kang, Yang Su Kim

Patent number: 8715254Abstract: A continuous Glomerular Filtration Rate (GFR) estimation system may include a Foley catheter, a continuous urine creatinine sensor, and a urine output monitor. The continuous GFR estimation system computes creatinine clearance as CrCl=(Ucr×Uvol)/Pcr×Tmin), where Ucr is urine creatinine in mg/dL, Uvol is urine volume in mL, Pcr is plasma (serum) creatinine in mg/dL, and Tmin is time in minutes. A Foley catheter may be used to withdraw urine from the bladder. The urine may be delivered to a urine output monitor that provides the Uvol value over a time Tmin. Attached to the catheter is the flow-through continuous urine creatinine sensor for providing the Ucr value. The remaining parameter is Pcr. Because serum creatinine levels do not change rapidly over time, a blood sample may be withdrawn prior to the start of the continuous GFR to obtain the Pcr value.Type: GrantFiled: February 18, 2008Date of Patent: May 6, 2014Assignee: C. R. Bard, Inc.Inventor: Vasu Nishtala

Patent number: 8715208Abstract: A method of monitoring or assessing the motion of the limbs of a body when performing repetitive cyclic activity uses inertial measurement units secured to each of the limbs to be monitored. The operation of all of the IMUs is synchronized by way of a pulse from a computer. On performing the repetitive cyclic activity such as walking, running, trotting or galloping, the outputs of the IMUs are assembled and analyzed in realtime, to determine the relative phase of the limb movements, from which an assessment of the gait may be made.Type: GrantFiled: November 13, 2009Date of Patent: May 6, 2014Assignee: European Technology for Business LimitedInventors: Diana Hodgins, Andrew Whalley
