The pacemaker is a Canadian invention that keeps hearts beating. The pacemaker revolutionized the medical treatment of cardiac patients — and kick-started the field of biomedical engineering. In the late 1940s, Canadian surgeons Dr. Wilfred G. Bigelow and Dr. John C. Callaghan were exploring open-heart surgery techniques at the University of Toronto’s Banting and Best Institute. Based on his wartime experience as a medic, Bigelow hypothesized that cooling the body and slowing the heart rate

For decades, NRC has worked at the very heart of biomedical engineering, a field that combines medical expertise with the design and problem solving of engineering. NRC inventions include the world’s first cardiac pacemaker and also the first to be powered by the human body. These devices – and the newer models they inspired – have saved countless lives around the world. When doctors wondered how to safely restart hearts that stop during surgery, NRC found that a gentle electrical stimulus would do

In 1956, John Callaghan conducted Canada’s 1st successful open-heart surgery at the University of Alberta (UAlberta) Hospital. While the surgery performed may be ‘simple’ by today’s standards, at the time it pushed the boundaries of modern heart surgery and knowledge. Pioneering advances In 1946, John Callaghan graduated from University of Toronto. While there, he and fellow cardia surgeon Wilfred Bigelow developed new cardiac surgical techniques to slow the heart for heart surgery. In 1951, the

Good day to you, my assiduous reading friend. Are you ready to drink from the fount of knowledge otherwise known as our blog / bulletin / thingee? Good for you. Let us continue our investigation of the bird impact research work done in Ottawa, Ontario, by the National Research Council of Canada (NRC). To do that, we will have to put on our seven decade boots, our nine decade boots actually, and travel back in time to the year 1930. The Engine Laboratory of the Division of Mechanical Engineering
