Abstract From the Canadian patent

An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion. The atrial defibrillator includes a first detector for sensing atrial activity of the heart, an atrial fibrillation detector responsive to the first detector for determining when the atria of the heart are in need of cardioversion and a second detector for detecting ventricular activations of the heart. The atrial defibrillator further includes a cardioverter for applying cardioverting electrical energy to the atria of the heart when the atria of the heart are in need of cardioversion and is responsive to the second detector for applying the cardioverting …

Why it's free to use

  • Filed October 19, 1993 and granted January 27, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 19, 2013.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 19, 2015.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
