| General Description : | Canadians are an inventive bunch. In fact, Canadian inventors have patented more than a million inventions—but far too many of us would be unable to name more than just a few. From Ginger Ale to insulin, from Bombardier’s “Ski-doo” to Plante’s goalie mask, plus the “Jolly Jumper,” instant mashed potatoes, the lawn sprinkler and the modern plastic garbage bag, items created from Canadian imagination and insight are a part of our daily lives. This stamp issue shines a spotlight on the “Made in Canada” leaps of science and creativity that have changed lives at home and abroad. In 1950, while studying hypothermia, Dr. John Hopps developed the world’s first cardiac pacemaker, which brought hope to those suffering with heart disease. In his experiments using radio frequency heating to restore body temperature, he learned that if a heart stopped beating due to cooling, it could be started again by mechanical or electric artificial stimulation. The first version of the now common medical device was external, far too large to be placed inside the human body. Improvements and miniaturization finally allowed for an unobtrusive version that could be surgically implanted. |
