Wireless Implantable System To Restore Memory

Tech ID: 27286 / UC Case 2014-959-0


UCLA researchers have developed a wireless implantable deep brain stimulation system to restore memory in individuals with traumatic brain injury.


Patients with Traumatic Brain Injury (TBI) represent a large and under-addressed population, with 1.7 million new cases in the US annually. Deep brain stimulation (DBS) is clinically used to improve symptoms in patients with Parkinson’s disease and epilepsy, but its application to other maladies (such as memory restoration due to TBI) has previously not been possible. New scientific and technological advances have opened up the possibility to apply DBS to additional applications.


Researchers have developed a wireless implantable DBS system for patients with TBI that delivers electrical brain stimulation. This new technology improves on their existing DBS electrode design and includes a more compact electronic unit, accomplished with improved data processing algorithms and power optimization strategies. These improvements have expanded the application for the device including use in patients with impaired memory due to TBI to restore and enhance memory.


  • DBS for:
    • Seizure prevention in epilepsy patients
    • Treatment of Parkinson’s Disease
    • Treatment of chronic depression
    • Restoring and enhancing memory in epilepsy and TBI patients
  • Spinal cord neurostimulation for alleviation of chronic pain
  • Functional restoration of impaired sensory systems (e.g. hearing, vision, tactile sensation)
  • Monitoring:
    • Neural monitoring in epilepsy
    • Cardiac rhythm management
  • Brain-Machine or Brain-Computer Interfaces (BMIs & BCIs) for neural control of prosthetic devices


  • Stimulation regulated by closed loop feedback system
  • Based on real-time neural recordings
    • High spatial resolution
    • High voltage sensing range
  • Highly compact
    • Wireless power and data transfer to/from implantable stimulator (no implanted battery)
    • Low power consumption
    • Wireless data streaming capability to mobile device/computer
    • Simultaneous stimulation and recording capability
    • Chronically implantable
