  • Patent number: 7794403
    Abstract: The invention relates to acquiring information concerning the hemodynamic status of the brain (or any other organ) by measuring and analysing the pulsatile properties of blood flow (velocities) in the organ's feeding vessels in relation to the pulsatile properties of the systemic arterial blood pressure. Provided is a system for the analysis of arterial blood flow velocity measurements, comprising means for receiving input signals delivered by an arterial blood flow velocity (FV) sensor and by an arterial blood pressure (BP) sensor, wherein said FV and BP signals are recorded simulataneously and continuously, further comprising means for processing and outputting signals, wherein said processing comprises calculating the pulsatile apparent resistance (PaR) or the Pulse Flow Velocity Mismatch (PFVM). Plotting PAR or PVFM against mean arterial blood pressure and/or end tidal CO2 levels can serve as an indicator for the effectiveness of imposed therapy.

  • Patent number: 7797028
    Abstract: Systems and methods for processing sensor analyte data, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. During initial calibration, the analyte sensor data is evaluated over a period of time to determine stability of the sensor. The sensor may be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. The calibration may be updated after evaluating the calibration set for best calibration based on inclusion criteria with newly received reference analyte data. Fail-safe mechanisms are provided based on clinical acceptability of reference and analyte data and quality of sensor calibration. Algorithms provide for optimized prospective and retrospective analysis of estimated blood analyte data from an analyte sensor.

  • Patent number: 7789837
    Abstract: A system and method for treating obstructive sleep apnea by terminating an obstructive sleep apnea event before the cessation of breathing occurs. The system has one or more microphones capable of detecting breathing sounds within an airway of a person and that generate signals representative of the breathing sounds and send the signals to a controller. When the controller detects a signal pattern that indicates the onset of an obstructive apnea event, the controller sends an alarm signal to a stimulus generator. The stimulus generator creates a stimulus to cause the sleeping person to move in a manner to terminate the obstructive sleep apnea event before cessation of breathing occurs. The obstructive sleep apnea event is terminated without waking the sleeping person and without causing the sleeping person physiological stress associated with cessation of breathing.

  • Patent number: 7778700
    Abstract: A method for measuring a brain wave comprises extracting positive and negative peaks from an electrocardiogram (EKG) signal reflecting heartbeat information, and positive peaks from an electroencephalogram (EEG) signal reflecting heartbeat-caused noise information and brain wave information. The positive peaks of the EEG signal are classified into a first peak group and a second peak group based on the positive peaks of the EKG signal. The first peak group is affected more greatly by the heartbeat than by the brain wave, and the second peak group is affected more greatly by the brain wave than by the heartbeat. Noise of the first and second peak groups is removed from the EEG signal.

  • Patent number: 7775984
    Abstract: At the time of blood pressure measurement by an electronic blood pressure monitor, a calculation portion calculates a blood pressure based on a pressure within a cuff detected by a pressure sensor, and outputs blood pressure data. A data storing portion stores the blood pressure data in a memory in association with condition data indicating a condition concerning the blood pressure. A manipulation portion is manipulated by a user to designate a desired condition from among a plurality of conditions. When the manipulation portion is manipulated, a read and display portion searches the memory based on the condition designated by the manipulation, reads the blood pressure data associated with the designated condition from the memory, and displays the read data on a display portion.

  • Patent number: 7775986
    Abstract: A therapy device having a blood pressure device and a regulating device for a time-variable regulation of the blood pressure, which decides, during a therapy procedure, dependent on detected blood pressure value, whether the blood regulation is continued with hypothetical or with real blood pressure values. The regulating device processes various categories of blood pressure values, i.e. blood pressure values obtained by the regulating device according to an implemented time schedule, blood pressure values requested by measurement and evaluation device, and blood pressure values requested by medical staff. Besides the regular triggers (RT) generated at regular intervals, the irregular triggers (IRT) and the quasi-regular triggers (QRT) requested externally at respective times are also evaluated.

  • Patent number: 7771460
    Abstract: Methods and apparatus for temperature modification of selected body regions including an induced state of local hypothermia of the brain region for neuroprotection. A heat exchange catheter is provided with heat transfer fins projecting or extending outward from the catheter which may be inserted into selected blood vessels or body regions to transfer heat with blood or fluid in the selected blood vessels or body regions. Another aspect of the invention further provides methods and apparatus for controlling the internal body temperature of a patient. By selectively heating or cooling a portion of the catheter lying within a blood vessel, heat may be transferred to or from blood flowing within the vessel to increase or decrease whole body temperature or the temperature of a target region. Feed back from temperature sensors located within the patient's body allow for control of the heat transfer from the catheter to automatically control the temperature of the patient or of the target region within the patient.

  • Patent number: 7771362
    Abstract: A method for performing an in-vivo calibration of a blood pressure sensor that is associated with a balloon of an in-vivo balloon system, the sensor and balloon being associated such that the sensor is in-vivo when the balloon is in-vivo. The balloon is inflated so that a gas pressure in the balloon system is indicative of a patient's blood pressure. The patient's blood pressure is monitored through two channels, the gas pressure and the sensor. The blood pressure measurements obtained by monitoring the gas pressure are used as reference, or “true,” blood pressure measurements to determine a mathematical relationship between blood pressure measurements obtained through the sensor and the reference blood pressure measurements. In this manner, future blood pressure measurements obtained through the sensor can be modified according to the mathematical relationship to generate calibrated blood pressure measurements.
