Here is some really great news for the heart patients. FDA has officially approved the first ever wire free heart pacemaker invented by Medtronic, the reputed medical technology company in US.
Medtronic’s Micra Transcatheter Pacing System works simply fantastic, just like other pacemakers to regulate heart rate in people with heart rhythm disorders. The only difference is that it does not use wired leads to make the electrical connection between the device and the heart.
Experts in US believe that this device’s approval is a big win for heart patients.
“The leadless pacemaker is a major breakthrough in the field of heart rhythm management and will benefit patients through its ease of insertion and elimination of the lead,” confirms Dr. Nicholas Skipitaris, who directs cardiac electrophysiology at Lenox Hill Hospital in New York City.
The traditional pacemakers have a wire or “lead” that connects the device to the heart, the procedure of placing such pacemakers usually means little or more invasive surgery.
“Through a small incision near the shoulder, the lead is guided through a blood vessel and attached to the inside surface of the heart,” he said. “The other end is connected to the pacemaker, which is then placed in a pocket under the skin. The incision is closed with sutures.”
The lead in these pacemakers may sometimes malfunction and become less reliable, causing infections in the tissue surrounding the lead. FDA understands the consequences of such pacemakers.
The new inch-long Micra device, on the other hand, can be implanted directly into the right ventricle chamber of the heart, with no wire lead needed.
“Insertion of the Micra is also easier as it does not require any incision,” Skipitaris said. “It is delivered to the heart through a long tube placed in a large vein in the groin area. The self-contained device is then anchored to the heart and the guiding tube is removed”
Micra’s groundbreaking benefits are bound to impact ab lot of heart patients who depend on the traditional pacemakers. It remains to be seen as to when the technology will come to India and if the patients here will really go for the switch.
