Sinai Hospital is an American private hospital based in Baltimore, Maryland, that was founded in 1866 as the Hebrew Hospital and Asylum. It is now a Jewish-sponsored teaching hospital that provides care for patients in the greater Baltimore City, Baltimore County and surrounding communities. The implantable cardioverter-defibrillator was invented here by the team of Dr. Michel Mirowski, Dr. Morton Mower, M. Stephen Heilman, and Alois Langer who are all in the National Inventors Hall of Fame for their achievement.
