  "title": "The First Implantable Cardiac Pacemaker",
  "original_title": "Medical cardiac pacemaker",
  "summary": "Wilson Greatbatch's 1960 patent for the first successful implantable heart pacemaker that used a battery to regulate heartbeat.",
  "what_it_does": "This patent describes a medical device designed to be implanted inside a patient to provide electrical stimulation to the heart. It uses a transistorized oscillator circuit to generate periodic electrical pulses that mimic the natural rhythm of a heart. These pulses are delivered to the heart muscle via electrodes to keep the heart beating at a steady, healthy rate. The device is powered by a battery, allowing it to function independently within the body for extended periods.",
  "what_it_does_not_cover": [
    "Does not cover external pacemakers that remain outside the body.",
    "Does not cover modern pacemakers with wireless communication or remote monitoring features.",
    "Does not cover non-electrical methods of heart rhythm regulation.",
    "Does not cover the specific chemical composition of modern lithium-iodine batteries."
