Scientists Develop World’s Smallest Pacemaker, Not Bigger Than a Vitamin Capsule

world's smallest pacemaker

The world’s smallest pacemaker which is not bigger than a large vitamin capsule has been successfully implanted in a patient in the US. The smallest pacemaker provides the most advanced pacing technology and it is for the patients who have bradycardia, slow heartbeat condition, usually fewer than 60 beats per minute.

The US Food and Drug Administration (FDA) approved the Micra Transcatheter Pacing System (TPS). The size of the pacemaker is the one-tenth of a traditional pacemaker and it is the only leadless pacemaker approved for use in the US.

Paul Schurmann, from Houston Methodist Hospital in the US who implanted the machine said, “This is not a complicated procedure and the first patient that we implanted is doing extremely well.”

Schurmann added, “I believe this gives us another tool to help save lives of patients with slow or irregular heart rhythms.” The device also does not require cardiac wires or a surgical pocket under the skin to deliver a pacing therapy.

When the lower heart rate is present the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise. It causes fatigue, dizziness, shortness of breath or fainting spells. Pacemakers help 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.

Schurmann said, “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.”

He added, “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.”

Micra TPS is designed uniquely. The feature enables it to be permanently turned off so it can remain in the body. The patients who need more than one device can implant it without the risk of electrical interaction.
