Bethesda, MD — Innovative Neurotronics, Inc. (IN, Inc.), a wholly-owned subsidiary of Hanger Orthopedic Group, Inc., announced today that it has received CE Mark approval for the WalkAide® System, a neuromuscular medical device that treats a condition of lower limb impairment known as foot drop. Achievement of the CE Mark indicates the WalkAide complies with EU regulatory requirements under the Medical Device Directive (MDD). This allows IN, Inc. to sell the WalkAide to the 25 nations in the European Union.

“Hundreds of thousands of people living with foot drop will now have access to technology that can allow them to regain their functionality and independence,” President of IN, Inc. Jeff Martin said. “The CE Mark serves as one more validation of IN, Inc.’s commitment to delivering high quality neuromuscular devices worldwide.”

Cleared for marketing by the FDA in September 2005 and officially launched in the United States on May 1, 2006, the WalkAide System treats patients with foot drop due to stroke, spinal cord injury, traumatic brain injury, and other pathologies such as multiple sclerosis and cerebral palsy.
