Patent number: 7431701Abstract: The invention disclosed herein provides a system and method for diagnosing lower urinary system conditions by receiving urodynamic data and subjective symptomatic impressions concerning a patient. The system and method then assigns weighted point values to the urodynamic data, for example, urethal pressure profiles due to sphincter contraction conditions such as urgency (2) and stress incontinence (4), and the subjective symptomatic impressions, quantifies norms for lower urinary system function, as a whole or in part, and quantifies recognized pathologies of lower urinary system conditions as degrees of departure from the norms. The system and method then determines a lower urinary system condition diagnosis of the patient, as a function of the degrees of departure from the norms, by invoking a set of rules to compare the weighted point values assigned and the quantified norms.Type: GrantFiled: September 13, 2001Date of Patent: October 7, 2008Inventor: Richard A. Schmidt

Patent number: 7418291Abstract: Disclosed is a device for measuring body fat of an animal. Embodiments include an input unit for entering individual information of the animal, a bioelectric impedance input unit for measuring the bioelectric impedance of the animal, and a morphological measurement value input unit for entering morphological measurement values for the girth and length of the body of the animal. An impedance-based calculation unit calculates a body fat rate based on the bioelectric impedance, and a morphological measurement value-based calculation unit calculates the body fat rate based on the morphological measurement values. A calculation switching unit checks to determine whether the resulting bioelectric impedance is proper, and automatically switches between the impedance-based calculation unit and the morphological measurement value-based calculation unit depending on the result of the determination.Type: GrantFiled: December 2, 2004Date of Patent: August 26, 2008Assignee: Tanita CorporationInventors: Yasuhiro Kasahara, Takashi Shiokawa

Patent number: 7328070Abstract: The disclosure describes a multi-tube pressure sensor to measure the pressure at two sites that may be used in a therapeutic incontinence control system. The system senses urinary sphincter pressure and urethral pressure and sends the information to a stimulator that is capable of stimulation therapy to control sphincter contractility, thus reducing unwanted urinary incontinence. Measuring sphincter pressure is accomplished through the use of a tube placed through the sphincter and urethral pressure is measured by a second tube placed within the urethra, both tubes may be attached to a single module implanted within the bladder. Pressure within the tube generates an electrical signal that is sent wirelessly to an implanted stimulator connected to a lead positioned near pelvic floor nerves. An external device may be used to wirelessly send information to the implanted stimulator and inhibit stimulation in order for the patient to empty the bladder.Type: GrantFiled: April 28, 2005Date of Patent: February 5, 2008Assignee: Medtronic, Inc.Inventors: Martin T. Gerber, Keith A. Miesel

Patent number: 7285099Abstract: Apparatus and methods for rotation test stimulus and analysis methods overcome many of the limitations of traditional clinical tests of peripheral vestibular function. An embodiment includes a rotational stimuli applied to the rotational motion for testing that includes two separate components, a bias component and a probe component. The bias component for rotational motion is designed to temporarily turn off vestibular responses in one ear while the responsiveness in the opposite ear is simultaneously evaluated using the probe component of the stimulus. Responses from application of these stimuli are analyzed by isolating and separating the bias response from the probe response. The bias and probe component responses are parameterized by applying curve fits of mathematical functions to the isolated bias and probe component responses. These parameters characterize the patient's vestibular function.Type: GrantFiled: January 21, 2004Date of Patent: October 23, 2007Assignee: Oregon Health & Science UniversityInventor: Robert J. Peterka

Patent number: 7223246Abstract: A procedure for diagnosing cochlear hydrops is based, in part, on an analysis of the patient's auditory brainstem response (ABR) to stimuli. The patient's ABR to a broadband click stimulus is recorded. A plurality of masked ABR's are also recorded, wherein the stimulus is masked by high-pass noise with a plurality of high-pass cut-off frequencies. The latency difference between the wave V component in the unmasked click alone response and the undermasked wave V component of a low cut-off frequency high-pass response is then calculated. If an undermasked component is not present, the normal wave V component is used. The measured latency difference is combined with another measure, such as the wave V amplitude ratio. A distribution of the combined measure is then plotted for the population and a threshold established for diagnosing cochlear hydrops. Alternatively, the joint distribution of the individual measures may be used in situations where the individual measures are known to be independent.Type: GrantFiled: June 7, 2004Date of Patent: May 29, 2007Assignee: House Ear InstituteInventor: Manuel Don

Patent number: 7211051Abstract: A method for reminding an individual to collect a urine specimen includes the steps of providing a pad or clip having a reminder area of a size such that the individual touches and discovers the pad, when preparing to urinate, and attaching the pad to the brief in the groin area, in a location where it will be encountered, and underneath an outer-garment, whereby the pad is hidden from view when in normal use, and whereby the individual, when preparing to urinate, will touch and discover the pad and thereby be reminded to collect the urine specimen. The pad or clip optionally is attached to the fly of a male brief or to the waistband of either a male or female brief. The invention accomplishes the reminder task by way of imposing behavior modification on the user by operating as a forced interruption to an otherwise established routine or ritual.Type: GrantFiled: March 11, 2003Date of Patent: May 1, 2007Inventor: John T.
