Researchers at Rice University, US, Creates a Wireless Pacemaker that Allows Direct Implantation in the Heart

• Researchers at Rice University along with their colleagues at the Texas Heart Institute, US, has recently made a wireless, battery-less pacemaker that has the advantage of being directly implanted into the patient's heart.
• This pacemaker receives its energy from the radio frequency radiation that is administered by an external battery pack.
• Till now, pacemakers that are used to maintain a stable heart beat, are placed in the chest or the abdomen.
• Unlike the new innovation, batteries are used to run the traditional pacemaker whereas electrical signals are transmitted by leads (wires).
• The new wireless pacemaker reduces further risks of bleeding and infection.
• Unlike other lead-less pacemakers that limit to a single chamber in the heart, direct implantation is possible with the new pacemaker that stabilizes several points of the heart.
