John H. Saringer is a professional engineer who graduated from the University of Toronto in 1977 and specializes in biomechanics and the development of products to accelerate healing and mitigate the effects of immobility.
Also in 1982, Saringer left academia to devote his full attention to building Toronto Medical Corp where he was the principal shareholder, CEO and director of research and development until the sale of the company in 1997.
[citation needed] Saringer operates his research lab from a 3,000 sq ft (280 m2) facility located on a 55-acre (220,000 m2) retreat centre where he lives.
The Venowave is a calf compression peristaltic pump that produces an upward volumetric displacement motion in order to increase blood circulation in the leg.
