U-M Health neurosurgeons complete first human implant of wireless brain computer interface
· News-MedicalNeurosurgeons at University of Michigan Health completed the first-in-human implant of a Paradromics Inc., wireless brain-computer interface, or BCI, as part of a national clinical trial for patients with difficulty speaking.
The participant struggles to speak due to motor neuron disease.
"We are incredibly excited to investigate the potential of this wireless BCI to restore communication for people who have lost the ability to speak due to neurological disease or injury," said Willsey, a Site Principal Investigator for the study who led the implant surgery.
"This has the potential to be a major step forward as we work toward our goal of helping treat people with paralysis who otherwise lack efficient and effective therapies for preserving communication."
The Connexus BCI is one of only a few wireless, fully implantable BCIs being tested in the United States.
Like other BCIs, it is designed to decode brain signals and translate them into action by allowing the user to control a device with their thoughts.
The Paradromics device contains 421 microelectrodes that capture brain signals from individual neurons. Those signals travel to a small transceiver in the user's chest that sends information to an external receiver.
Our goal is to restore natural communication for people who have lost the ability to speak and help them stay connected with their loved ones. We're proud to partner with University of Michigan Health on this first-in-human study as we build the foundation for the next generation of clinical BCIs." Matt Angle, Ph.D., CEO and Founder of ParadromicsEnrolling our first participant at University of Michigan is a defining moment for our company and for the field.
The U.S. Food and Drug Administration granted Paradromics an Investigational Device Exemption (IDE) to begin the Connect-One clinical study in November 2025. Michigan Medicine is one of three sites enrolling participants for the study.
"I'm honored to be leading this study together with Drs. Willsey and Rubin."
The participant will be followed for six years following the BCI implant. In addition to meeting with the study team regularly, she will continue to receive motor neuron disease care from the Stanford Morris ALS Clinic at U-M Health.
Motor neuron disorders are a group of diseases that impact the function of the brain, brainstem and spinal cord motor neurons. This includes amyotrophic lateral sclerosis (ALS), which is the most common motor neuron disorder, and primary lateral sclerosis (PLS).
Given the impact on effective communication for those living with such conditions, wireless BCI devices represent an important area of research.
"It is critical to preserve communication for all those living with motor neuron disease to keep individuals connected to their families and friends, and to preserve independence and quality of life," said Stephen Goutman, M.D., M.S., Director of the Stanford Morris ALS Clinic, Associate Director of the Scott Pranger ALS Center and Harriet Hiller Research Professor at U-M.
"We are so fortunate to be able to partner with Dr. Willsey and the incredible neurosurgical team here at U-M Health as they work to bring these devices into the clinic and make motor neuron diseases more livable."
"Advances in brain-computer interfaces and neuromodulation are rapidly reshaping what is possible in the treatment of neurological disease," Sagher said.
"Our clinician-scientists are committed to developing and advancing these technologies and ensuring that patients have access to the most innovative and effective therapies available. When patients come to Michigan Medicine for their care, they should know they are being treated at a center helping define the future of neuroscience and neurosurgical care."
