Today we are sharing a fascinating Medtronic patent combining cardiac monitoring with brain stimulation. (As mentioned, we are featuring foundational Pervasive Neurotech patents, from older to newer by issue date)

U.S. Patent No. 8,209,009: System and method for segmenting a cardiac signal based on brain stimulation

  • Assignee(s): Medtronic, Inc.
  • Inventor(s): Jonathon E. Giftakis, Nina M. Graves, Mark Turner Rise
  • Technology Category: Neuro-monitoring
  • Issue Date: June 26, 2012

SharpBrains’ Take:

This patent considers the inter-relationship and co-occurrence of activity between brain and heart. The “Background of the Invention” section provides examples of the importance of considering activity between these two major organs, for instance in dealing with sudden unexpected death in epilepsy (SUDEP) often associated with heart and pulmonary dysfunction or indicators. A compelling 68 claims (with 5 weaving independent claims) cover various aspects and features of the disclosed embodiments, including both monitoring and stimulation elements. The co-consideration of cardiological and neurological health, extensive specification (including 59 illustration sheets and 32 pages of written material) and compelling claim set are among the factors contributing to make the ‘009 patent a key non-invasive neurotechnology patent.


A medical device system that includes a brain stimulating element, cardiac monitoring element and a processor. The processor is configured to receive a brain stimulation signal from the brain stimulating element and a cardiac signal from the cardiac monitoring element. The processor is further configured to determine at least one reference point for a stimulation event time period by evaluation of the brain stimulation signal. The processor further identifies a first portion of the cardiac signal based on the at least one reference point of the stimulation event time period.

Illustrative Claim 44. A method of stimulating brain and monitoring cardiac activity comprising:

  1. stimulating the brain during a stimulation event time period;
  2. monitoring the heart and outputting a cardiac signal indicative of activity in the heart;
  3. determining, with electronic circuitry, at least one reference point for the brain stimulation event time period by evaluation of a stimulation state indicating stimulation of the brain by the brain stimulating element; and
  4. identifying, with the electronic circuitry, a first portion of a recording of the cardiac signal based on the at least one reference point of the brain stimulation event time period.
