Officials say about 4 million people worldwide have traditional pacemakers, those small box-like implantations in their chest with wires connected to the heart to make sure their heart beats in a proper rhythm. But one man in Central Florida has a brand new pacemaker, that weighs 2 grams (the weight of 2 paperclips) and it sits directly inside his heart in a single chamber; no more box under the skin, no more wires to the heart.
It is a device called Nanotism manufactured by St. Jude Medical. This new pacemaker is being tested in the United States as part of the LEADLESS II Clinical Trial. Developed for patients with bradycardia – a heart rate that is too slow – the Nanostim device is designed to be placed directly in a patient’s heart without the visible lump, scar and insulated wires (called leads) required for conventional pacemakers.
The first implant procedure in Central Florida was performed by Drs. George Monir and Scott Pollak, electrophysiologists at Florida Hospital.“The traditional pacemaker requires surgery and insertion of a wire called a lead into the heart,” said Dr. Pollak. “Over time the leads can degrade and malfunction over a period of years. The new technology is implanted through the groin and directly into the heart meaning there is a decreased risk of this device failing over time.”
