  • Patent number: 7279007
    Abstract: A method and a device for improving cardiac function are provided. The device is packaged in a collapsed state in an end of a catheter. Portions of a frame construction of the device spring outwardly when the catheter is withdrawn from the device. Anchoring formations on the frame construction secure the frame construction to a myocardium of the heart. A membrane secured to the frame construction then forms a division between volumes of an endocardial cavity of the heart on opposing sides of the membrane.
    Type: Grant

  • Publication number: 20030109770
    Abstract: A porous membrane is inserted into a ventricle of a heart. The porous membrane creates a relatively hemostatic volume in which a thrombus can grow. Blood can still pass through fenestrations of the membrane into and out of the hemostatic volume. The fenestrations reduce pressures that act on the membrane, and so reduce stresses within the membrane. The flow characteristics through the hemostatic volume promote growth of the thrombus from a base of the hemostatic volume. The thrombus grows to slightly larger than the original size of the hemostatic volume so as to provide support for the membrane. Any remaining stresses within the membrane are thereby substantially eliminated. The thrombus shrinks over an ensuing period of time, with the membrane merely acting as a barrier to which an outer wall of the myocardium retracts. The function of the membrane is then complete, and may be absorbed.

  • Patent number: 6436052
    Abstract: Systems and methods providing for the determination of an individual's rate of oxygen consumption, in order to determine the amount of work that is performed by the individual's body. A heart monitor measures the heart rate of the individual and an accelerometer measures the acceleration of the body. The heart rate and acceleration outputs are stored locally on a storage device. The outputs can be downloaded to a local base station, that in turn transmits the outputs to a central clearinghouse. The clearinghouse receives and stores the output on a central mass storage device. At the clearinghouse the raw data is processed into a usable form and the rate of oxygen consumption is mathematically determined in order to determine the amount of work that is performed on the individual's body.

  • Patent number: 6306125
    Abstract: System for delivering an implant to tissue to be treated which includes a housing, a delivery head which carries the implant and is movable between extended and retracted positions relative to the housing, an actuator mounted in the housing and connected to the delivery head for moving the delivery head from the retracted position to the extended position and back to the retracted position, and a depth gauge mounted to the housing for determining how far the implant is inserted into the tissue when the delivery head is moved to the extended position.

  • Patent number: 6263880
    Abstract: Method of enhancing blood flow in tissue wherein an implant is non-ablatively introduced into the tissue in order to stimulate production of angiogenic agents by the tissue, the agents produced by the tissue are absorbed into the implant, where they are stored, and the stored agents are released back into the tissue when the production of agents by the tissue subsides. The implant is fabricated of a bioresorbable material and is resorbed into the tissue after the agents are released. In some embodiments, an exogenous angiogenic agent in included in the implant and released into the tissue along with the agents which are produced by the tissue and absorbed by the implant.

  • Patent number: 5758652
    Abstract: A system and method for measuring the heart condition of a patient is disclosed. The system includes a measuring device used to generate an absolute blood pressure signal indicative of the absolute blood pressure of the patient. A processing element receives and processes the absolute blood pressure signal, and generates (1) a filtered blood pressure signal by removing certain variations from the absolute blood pressure signal caused by respiratory activity of the patient; and (2) a set of parameters derived from the filtered blood pressure signal. The set of parameters measure certain aspects of the absolute blood pressure signal which are indicative of the performance and condition of the patient's heart.

  • Patent number: 5743267
    Abstract: A system and method for monitoring a physiological attribute of a patient is disclosed. The system includes a measuring device to measure an absolute physiological attribute of a patient and to generate an absolute physiological attribute signal. The present invention also includes a processing element to receive the measured absolute physiological attribute signal. The processing element then generates a filtered physiological attribute signal by substantially removing the effects of certain bodily functions from the absolute physiological attribute signal and other artifacts of measurement. The processor also generates a set of parameters derived from the filtered physiological attribute signal which are indicative of the health and condition of the patient.
