Northstar's stroke therapy device involves the precise delivery of low levels of electricity to the surface of the brain (the cortex) via an implanted stimulator system.

“We have spent years developing a device system intended to help improve function in stroke survivors months or even years after their strokes,” said Allen Wyler, MD, Northstar's medical director, in a press release.

Initial research has demonstrated that cortical stimulation of healthy brain tissue near the area damaged by the stroke, in combination with rehabilitation, may facilitate neuroplasticity and improve function.
