Meet Gerard Langevin, a 65-year-old Quebec man who is the only living Canadian without a pulse:
Dr. Renzo Cecere implanted the “Heartmate II” mechanical heart into Gerard Langevin in an three-hour operation Nov. 23. ...
The new mechanical heart, which is powered by batteries located in pouches on Mr. Langevin's body, provides a continuous flow of blood so the patient has no pulse.
“Mr. Langevin happens to be the only individual currently living in Canada without a pulse and without a measurable blood pressure,” Dr. Cecere said Wednesday.
