  • A U.S.-based developer of a brain-computer implant is reportedly preparing to carry out major testing of its device on humans.
  • 2
  • The company is called Synchron.
  • 3
  • The Reuters news agency reported that Synchron recently launched on online system that permits patients to express interest in taking part in a large research study, or trial.
  • 4
  • The company has also been in contact with more than 100 research centers that want to support the study, Synchron chief executive Thomas Oxley told Reuters.
  • 5
  • Synchron's device is known as a brain-computer interface.
  • 6
  • It is designed to treat individuals who experience paralysis caused by injury or disease.
  • 7
  • The device contains a small computer built to electronically communicate with the brain.
  • 8
  • The first tests aim to use the brain-computer interface to process brain signals to help paralyzed patients type on a computer.
  • 9
  • Synchron's interface is similar to a device currently being tested by its American competitor, Neuralink.
  • 10
  • One difference is that Neuralink's device is designed to be implanted inside the skull.
  • 11
  • Synchron's device uses a less invasive implant method known as endovascular.
  • 12
  • The company says this involves a vein carrying the device into a part of the brain known as the motor cortex.
  • 13
  • This part of the brain produces signals to direct body movements.
  • 14
  • Synchron is farther along in the development of its implant than Neuralink, Reuters reports.
  • 15
  • Neuralink's progress has mainly been announced by company chief Elon Musk on the X social media service that he owns.
  • 16
  • So far, Neuralink has said its device has been implanted in one paralyzed patient.
  • 17
  • Testing implants in patients with brain damage can be difficult.
  • 18
  • This is because an individual's brain may be so severely damaged that there is not effective signaling to record.
  • 19
  • Synchron's Oxley said the U.S. Food and Drug Administration (FDA) asked his company to test stroke patients using a non-invasive method to see if they would be good implant candidates.
  • 20
  • In 2020, Synchron said experiments involving paralyzed patients in Australia found the individuals could use its device to type letters into a computer at a higher rate than in earlier studies.
  • 21
  • Synchron received U.S. approval in July 2021 to carry out early testing.
  • 22
  • It has implanted its devices in six patients so far.
  • 23
  • Tests involving four patients in Australia showed no serious side effects, the company has reported.
  • 24
  • Synchron says it will be examining data from its current testing to prepare for the larger study.
  • 25
  • The company must still receive FDA approval to move forward with the new study.
  • 26
  • Several U.S. hospitals have cooperated with Synchron on its current testing program.
  • 27
  • These include Mount Sinai in New York, the University at Buffalo Neurosurgery and the University of Pittsburgh Medical Center (UPMC).
  • 28
  • The company has said it hopes to involve these same medical centers in the larger trial.
  • 29
  • Dr. David Lacomis is chief of UPMC's Neuromuscular Division.
  • 30
  • He told Reuters his team is still involved in the current testing program and said "the study is going well."
  • 31
  • The Department of Neurosurgery in the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo has two patients in the current test program.
  • 32
  • The head of that effort is department chief Dr. Elad Levy.
  • 33
  • He told Reuters, "the first and only stroke patient" is taking part in the study.
  • 34
  • Levy said he feels that is important because this is a large population that might see improvements from Synchron's device.
  • 35
  • He added that he was hopeful and excited about the new research and future deployment of the technology.
