Kevin T Ousdigian, Vasant Padmanabhan, Paul J DeGroot, Walter H Olson, Vinod Sharma, Cameron J Kaszas, Paul G Krause: Combined anti-tachycardia pacing (ATP) and high voltage therapy for treating ventricular arrhythmias. Medtronic, Michael C Soldner, Girma Wolde Michael, May 10, 2005: US06892094 (41 worldwide citation)

A system and method for treating an arrhythmia of the heart, involves delivery of anti-tachy pacing (ATP) pulses to the heart, possibly followed by the delivery of a high-voltage shock. ATP delivery is controlled such that the time delivery of any high-voltage shock is not affected by the prior deli ...

David E Ritscher, Kevin T Ousdigian: Adaptive memory prioritization for implanted medical devices. Medtronic, Girma Wolde Michael, Daniel G Chapik, October 31, 2006: US07130678 (37 worldwide citation)

In general, the invention is directed towards techniques for adaptively prioritizing cardiac episode data in a memory of an implanted medical device (IMD). More specifically, the IMD receives new cardiac episode data, assigns each piece of data a priority value, and stores the data in a memory of th ...
