Rabbits pilot wireless medical implants

The pacemaker and neurostimulator are two of those devices, and with the help of rabbits, researchers are on their way to making some amazing improvements!

When a patient has one of these devices implanted, it’s understood that they will need follow-up surgeries at certain intervals to replace the battery. Pacemaker, neurostimulator, and spinal cord stimulator batteries last, on average, 5-10 years. But recently, researchers have been able to regulate a rabbit’s heart with a pacemaker that operates off wireless energy! This specific implant is only 3mm long. You can imagine the reduced recovery time after a surgery to implant something this size!

While some doctors are skeptical of life-supporting devices relying on external power, researchers are working to adapt this technology for other types of implants as well. Neurostimulator and spinal cord stimulator batteries tend to be about half the size and thickness of a deck of cards, and often, patients experience a good amount of pain at the battery implantation site. Eliminating the need for a battery for these units could make a huge difference for patients- let’s hope that this technology proves successful!

Do YOU have a battery-powered implant? If so, I’d love to hear your thoughts- do you think this technology will help you?
