Patent number: 11992360Abstract: A system and method for heart rhythm detection and reporting are disclosed. This cardiology system includes a biosensor system and a data analysis system. The biosensor system is worn by an individual and includes sensors that detect biosignals including infrasonic signals from the individual. The data analysis system receives the biosignals from the biosensor system, and determines heart rhythms of the individual based upon the biosignals. The system identifies at least some of biosignals as being associated with cardiovascular activity, such as pulse wave signals. Preferably, the biosensor system is an in-ear biosensor system that detects the biosignals via left and right earbuds placed within or at ear canals of the individual. The system can also identify arrhythmias including atrial fibrillation (Afib) arrhythmias from the heart rhythms, report information to health care and safety professionals and update medical records of the individuals.Type: GrantFiled: July 17, 2020Date of Patent: May 28, 2024Inventors: Anna Barnacka, Charles R Bridges, Karlen Shahinyan

Patent number: 11986631Abstract: Techniques for modeling therapy fields for therapy delivered by medical devices are described. Each therapy field model is based on a set of therapy parameters and represents where therapy will propagate from the therapy system delivering therapy according to the set of therapy parameters. Therapy field models may be useful in guiding the modification of therapy parameters. As one example, a processor compares an algorithmic model of a therapy field to a reference therapy field and adjusts at least one therapy parameter based on the comparison. As another example, a processor adjusts at least one therapy parameter to increase an operating efficiency of the therapy system while substantially maintaining the modeled therapy field.Type: GrantFiled: July 14, 2020Date of Patent: May 21, 2024Assignee: Medtronic, Inc.Inventors: Martin T.
