Patent Issued for Physiological Response to Posture Change

June 30, 2014

By a News Reporter-Staff News Editor at Cardiovascular Week -- A patent by the inventors Hatlestad, John D. (Maplewood, MN); Libbus, Imad (St. Paul, MN); Lewicke, Aaron (Forest Lake, MN), filed on March 8, 2012, was published online on June 17, 2014, according to news reporting originating from Alexandria, Virginia, by NewsRx correspondents (see also Cardiac Pacemakers, Inc.).

Patent number 8753276 is assigned to Cardiac Pacemakers, Inc. (St. Paul, MN).

The following quote was obtained by the news editors from the background information supplied by the inventors: "A person's health status may be determined by analyzing physiological parameters such as heart rate, respiration pattern, and blood pressure, just to list a few. These physiological parameters may follow different patterns for a healthy individual versus a person who is suffering from some form of ill health. Some physiological parameters are affected by the posture of the body. Additionally, the present inventors have recognized that the response of these parameters to changes in posture may be affected by the person's state of health. Consequently, the present inventors have recognized that medical and health care profession would benefit from a system and method to detect, capture, and analyze the effect of posture change on such physiological parameters."

In addition to the background information obtained for this patent, NewsRx journalists also obtained the inventors' summary information for this patent: "In certain examples, an implantable medical device includes a controller circuit, a posture sensing circuit, and a physiological sensing circuit. The controller circuit senses a change in a physiological signal as a result of a change in posture, and can optionally respond to that change. In certain examples, the controller circuit identifies a heart failure condition or status using the change in the physiological signal.

"This summary is intended to provide an overview of the subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. The detailed description is included to provide further information about the subject matter of the present patent application."
