Tofy Mussivand (Persian: توفیق موسیوند‎, born in Hamedan) is an Iranian physician and engineer and a cardiologist in Canada.

He studied Medicine and Engineering at Tehran University and University of Alberta. Tofy Mussivand is known for the invention of Artificial Cardiac Pump. Cardiac pump or cardiac bypass pump or heart-lung machine temporarily takes over the function of breathing and pumping blood for a patient. It generally has two parts, the pump and the aerator. Cardiac pumps are most often used in heart surgery, so that a patient's heart can be disconnected from the body for longer than the twenty minutes or so it takes a prepared patient to die.

Mussivand received his undergraduate education and training in engineering and management. Following many successful years in senior positions in Canadian government, crown corporations, and the private sector, Dr. Mussivand went on to receive his doctorate in Medical Engineering and Medical Sciences at the University of Akron and Northeastern Ohio Universities College of Medicine. Thereafter, Mussivand joined the Cleveland Clinic Hospital and Research Foundation where he gained knowledge and experience in the development of medical devices, artificial hearts, and cardiac care. In 1989, Mussivand was invited to return to Canada to continue his pioneering work in medical devices.
