Sound can pass through the FDA-cleared ClearFit neuro reconstructive implants from Longeviti Neuro Solutions. The implants are made of polymethyl methacrylate (PMMA), which allows for ultrasound monitoring of patients after they’ve had complex brain procedures.
Baltimore-based Longeviti is collaborating with Vancouver, British Columbia-based Clarius. Clarius makes the HD3 portable, handheld ultrasound system and adapted its ultrasound app for easier use of its scanners for neurological applications.

Longeviti said the two technologies combined can help patients minimize radiation exposure from CT scans, citing a study that suggested ultrasound imaging through sonolucent implants is a safe alternative with an estimated savings of up to $4,000 per patient.

Longeviti Chief Medical Officer Dr. David Langer described the combination of the two company’s technologies as a “neurosurgical stethoscope.”
“The Clarius device gives the neurosurgeon and all advanced care practitioners the ability to perform bedside ultrasound with a tool in their pocket,” said Langer, a neurosurgeon and chair of neurosurgery at Lenox Hill Hospital in New York City. “… I am certain that this will have an enormous impact on neurosurgical care going forward.”
Clarius says its wireless scanners are purpose-built for every specialty and cost much less than traditional ultrasound systems.

“Our partnership with Longeviti is another excellent example of how the open-platform design of Clarius ultrasound enables us to partner with other medical innovators dedicated to improving patient care,” Clarius President and CEO Ohad Arazi said. “We look forward to working with Longeviti to expand the use of handheld ultrasound for neurology and ultimately help outcomes for cranial implant patients.”
