Smallest Pacemaker

World’s smallest pacemaker is about the size of a coin which can be implanted in patients to reinstate the heart’s normal rhythm, in situations like unable to pump enough oxygen-rich blood, experts have said.

A pacemaker is a small device which placed in the abdomen or chest to control abnormal heart rhythms. It uses electrical pulses to prompt the heart to beat at a normal rate.

It is used to treat Arrhythmias, which are problems with the rhythm or rate of the heartbeat. During Arrhythmia, the heart can beat too slow, too fast or irregular rhythm. A pacemaker can relieve some arrhythmias symptoms like fatigue and fainting by sending electrical impulses to the heart.

Pacemakers are the most used way to treat bradycardia to restore the heart’s normal rhythm and relieve symptoms.

Houston Methodist Hospital in Texas is offering a US Food and Drug Administration (FDA) approved Micra Transcatheter Pacing System (TPS), the smallest pacemaker for patients suffering from bradycardia, means a slow heart beat, defined as a heart rate of under 60 beats per minute.

World’s smallest pacemaker is about the size of a large vitamin and unlike traditional pacemakers, it does not require cardiac wires or a surgical “pocket” under the skin to deliver a pacing therapy.

Paul Schurmann, Managing Director at Houston Methodist Hospital 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 also 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.”

Micro TPS was designed with a unique feature which enables it to be permanently turned off so that new device can be implanted without any risk of electrical interaction.
