IMRIS pediatric horseshoe headrest enables iMRI for even the youngest neurosurgery patients

Le Bonheur neurosurgeons complete first cases using MR-safe headrest designed specifically for intraoperative imaging in VISIUS Surgical Theatre.

MINNEAPOLIS, March 26, 2014 – IMRIS Inc. (NASDAQ: IMRS; TSX: IM) ("IMRIS" or the “Company”) today announced the initial uses of its neurosurgical horseshoe headrest with VISIUS® intraoperative MRI (iMRI) during two cases at Le Bonheur Children’s Hospital in Memphis, TN. The IMRIS horseshoe headrest is the world’s first MR-safe and CT-compatible horseshoe headrest on the market for the positioning of patients ranging from neonatal to adult during neurosurgical procedures requiring intraoperative imaging in the VISIUS® Surgical Theatre.

“The IMRIS horseshoe headrest worked well for providing the ideal prone positioning during this procedure,” said Dr. Frederick Boop, Chairman of the Department of Neurosurgery and Co-director of Le Bonheur’s Neuroscience Institute who performed the first case of a tumor surgery on a five- year-old child. “In the past we would not have had an iMRI option for this child and now the tumor is completely gone. We have now advanced our treatment to a group of kids for whom it will really make a difference. Even our youngest and most fragile patients can benefit from intraoperative MR, which would not have been possible otherwise.”

The second neurosurgical case the following day involved a four-month-old baby operated on by Dr. Paul Klimo, chief of the division of pediatric neurosurgery at Le Bonheur and University of Tennessee Health Science Center.

The device provides non-pinned (or non-rigid) head support in prone, lateral, and supine positions during head, neck and cervical spine surgeries where use of a head fixation device (HFD) – a clamp-like device – is not desirable because the skull is too fragile for pinning. These patients may be babies whose skulls are still soft or older patients with weakened skull bones. This headrest may also be useful for other applications not requiring rigid fixation, such as those that access the skull through the nose.
