World’s smallest pacemaker, size of a vitamin capsule, unveiled

By February 6, 2017Latest News

The world’s smallest pacemaker, which is about as big as a large vitamin capsule and provides the most advanced pacing technology, has been successfully implanted for the first time in a patient in the US, scientists say.
The pacemaker is for patients with bradycardia, a condition characterized by a slow heart rate, usually fewer than 60 beats per minute.
The Micra Trans catheter Pacing System (TPS), recently approved by the US Food and Drug Administration (FDA), is a new type of heart device that provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker and is the only leadless pacemaker approved for use in the US.

“This is not a complicated procedure and the first patient that in which it was implanted is doing extremely well.”
Now we believe this gives us another tool to help save lives of patients with slow or irregular heart rhythms.
The device is the size of a large vitamin, and unlike traditional pacemakers, it does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy.
When a lower heart rate is present, the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, fatigue, shortness of breath or fainting spells.
Pacemakers are the most common way to treat bradycardia to help restore the heart’s normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.
The device is small enough to be delivered through a catheter and implanted directly into the heart, providing a safe alternative to conventional pacemakers without the complications associated with leads.
The device also allows us to automatically adjust pacing therapy based on a patient’s activity levels and another positive is the battery can last up to 10 years.

For patients who need more than one heart device, the miniaturized Micra TPS was designed with a unique feature that enables it to be permanently turned off so it can remain in the body and a new device can be implanted without risk of electrical interaction.
