  • Implantable intravascular pressure determining device and method
    Patent number: 6860857
    Abstract: In an implantable intravascular pressure determining device and method, a pressure sensor generates a raw pressure signal and an acceleration sensor measures acceleration in a patient. Time intervals are identified wherein the raw pressure signal accurately represents the intravascular pressure, these intervals being identified as the time intervals wherein the measured acceleration is below a predetermined threshold. The raw pressure signal is processed, to generate a processed signal which is used as an intravascular pressure signal, only in the aforementioned time intervals.
    Type: Grant
    Filed: February 19, 2002
    Date of Patent: March 1, 2005
    Assignee: St. Jude Medical AB
    Inventors: Kjell Norén, Seven-Erik Hedberg, Kenth Nilsson
  • Implantable intravascular pressure determining device and method
    Patent number: 6589184
    Abstract: In an implantable intravascular pressure determining device and method, a pressure sensor generates a raw pressure signal, an acceleration sensor generates an acceleration signal, and an evaluation unit determines a disturbance pressure signal from the acceleration signal. A processed signal is generated as the difference between the raw pressure signal and the disturbance pressure signal. The processed signal corresponds to intravascular pressure.
