MRIS, MDA Advancing Image Guided Surgical Robotics Program

Tue, 09/20/2011 - 5:11am

PRNewswire/ - IMRIS Inc. and MacDonald, Dettwiler and Associates Ltd. today announced an agreement for the final phases of development on IMRIS's MR guided surgical robot. IMRIS and MDA began work on a robotic surgery system in 2010, targeting microsurgery and biopsy-stereotaxy applications on the brain with sub-millimeter precision. The goal is to bring the capabilities of surgical robotics together with real time MR imaging in a fully integrated IMRIS surgical suite under the full control of the neurosurgeon.

Ultimately, the technology is expected to extend into a broad range of surgical applications. The system features two robotic arms that can manipulate MR-compatible tools at a microscopic level from a remote workstation. The surgeon sees detailed three-dimensional images of the brain and the surgical tools, and uses hand controllers equipped with enhanced touch sensation that allow the surgeon to feel  tissue through the robotic arms and surgical tools and apply appropriate pressure as they operate.

A clinical trial utilizing the first generation of the robot on a cohort of 120 patients is currently underway, led by Garnette Sutherland, MD, Professor of Neurosurgery, at Calgary's Foothills Hospital. The first public demonstration of IMRIS' robotic technology will be at the Congress of Neurological Surgeons in Washington, D.C.where Dr. Sutherland will share his experiences on October 3 and 4 with delegates visiting the IMRIS booth.

Given current development plans, IMRIS anticipates being in a position to seek regulatory approval as early as the second quarter of 2012. IMRIS is considered a leader in providing image guided therapy solutions that can be fully integrated into surgical and interventional suites.
