EaglePicher Medical Power recently announced the development of the world’s smallest implantable-grade medical battery measuring more than 50% smaller and lighter than any of the commercially available products. Here’s more from EaglePicher:
The battery’s size and shape (cylindrical, 0.260″ long x 0.090″ diameter) enables a device so small that it can be deployed via a minimally-invasive catheter procedure rather than traditional implantation surgery…
Electrical capacity exceeds the original design objective by a factor of five with the result that it can theoretically power the device for more than 15 years. The Micro Battery will create new opportunities for device manufacturers in Neurological Catheters, Cardiovascular Monitoring, and Neural Prostheses (Retinal implants, Cochlear Implants).
