Patrick M McCarthy, Cyril J Schweich Jr, Todd J Mortier, Peter T Keith, Michael J Kallok: Methods and devices for improving cardiac function in hearts. Myocor, Finnegan Henderson Farabow Garrett & Dunner, June 18, 2002: US06406420 (441 worldwide citation)

Various methods and devices are disclosed for improving cardiac function in hearts having zones of infarcted (akinetic) and aneurysmal (dyskinetic) tissue regions. The methods and devices reduce the radius of curvature in walls of the heart proximal infarcted and aneurysmal regions to reduce wall st ...

Michael J Kallok: Multiple stimulation electrodes. Medtronic, Harold R Patton, Daniel W Latham, John L Rooney, January 25, 1994: US05281219 (133 worldwide citation)

A technique for reducing fatigue associated with artificially stimulated contractions of muscle tissue. The stimulation of the muscle tissue is associated with treatment of a particular medical condition, such as obstructive sleep apnea. For this application, the muscles of the upper airway are stim ...
