The Device Development and Biological Testing Core supports discovery work in the nervous system, prototyping of innovative implantable and wearable medical devices, testing of neuro-inflammation and biological reactivity to implantable micro-technologies.​  A Quality Management System (QMS) for medical device development has been implemented to prepare our devices for manufacturing and ensure regulatory compliance.


This core houses the only Good Laboratory Practice (GLP) preclinical testing facility in Western Canada.  It supports the completion of preclinical research services to help University researchers and client companies develop therapeutic products or establish product safety in compliance with regulatory approval under the Organization for Economic Cooperation and Development (OECD) Good Laboratory Practice regulations or FDA 21CFR Part 58.

CAPABILITIES

  • Developing new strategies and therapeutics to improve device compatibility and integration with
    ​the central nervous system
  • Studying the relationship between inflammation and psychiatric disorders, neurodegenerative disorders and implanted device biocompatibility
  • Studying the bidirectional relationship between inflammation and neuropathology
  • Identifying, targeting and modulating specific microglial phenotypes to promote recovery or repair
    of injured tissue
  • 3D hydrogel culture for testing impact-induced injury and device biocompatibility
  • Development, design and prototyping techniques applied to Micro and Nano-Electro-Mechanical-Systems (MEMS/NEMS) and applying it in sensors used in remote Structural Health Monitoring of critical systems such as pipelines, civil transportation systems, automotive and aerospace systems

    ​in a coordinated manner
  • Developing the device for long-term testing in persons with spinal cord injury
  • Advancing the development of models and instrumentation to study the biomechanics of injury
    and protection devices
  • Developing miniature stimulators and sensors for wearable devices for biomedical applications
    and biomechanical assessment of human motion
  • Miniature stimulators for devices such as the SOCC (Smart Ongoing Circulatory Compressions)
    for preventing the formation of deep vein thrombosis (DVT)
  • Lends support to numerous projects requiring microfabrication
  • Experience with polymer and standard micromachining technologies with applications in the field
    ​of micro-electro-mechanical systems (MEMS), microfluidics, soft robotics, nerve injury and bioinspired systems
