Integra LifeSciences Announces Launch of New Cortical Stimulator for Mapping Brain Functions in Cancer and Epilepsy Patients

PLAINSBORO, N.J., Sept. 21, 2007 (PRIME NEWSWIRE) — Integra LifeSciences Holdings Corporation (Nasdaq:IART) announced the release of the OCS2 Ojemann Cortical Stimulator at this week’s annual meeting of the Congress of Neurological Surgeons in San Diego, CA. The OCS2 Ojemann Cortical Stimulator has an FDA clearance in the United States and a CE Mark Certification in the European Union.

Originally developed in collaboration with Dr. George Ojemann at the University of Washington, the new device contains updated electronics and an improved design for usability. The Ojemann Cortical Stimulator is the industry standard for cortical stimulation procedures that identify and map eloquent tissue during brain surgery. It is a compact, battery-powered unit, which supplies up to 20 milliamps constant current, and has easy to use controls for treatment in awake and anesthetized patients.

The neurosurgeon’s primary goal, for patients with brain cancer and epilepsy, is to completely remove abnormal tissue while sparing normal areas. During surgery, the neurosurgeon places the OCS probe onto the brain’s cortex in all areas surrounding tissue considered for resection. Responses to direct cortical stimulation reveal the functional areas, either by evoking an observed motor response in an anesthetized patient, or for an awake patient, triggering sensations or causing an interruption in the patient’s speech. These responses help the neurosurgeon determine the boundaries between abnormal and normal areas, and facilitate removal of the cancer or epileptic region.

“We are excited to bring this updated technology to the U.S. and international markets. The Ojemann Cortical Stimulator allows surgeons to accurately identify eloquent tissue and reduce language and motor defects while performing resections,” said Jason D. Ellnor, director of marketing for Integra’s stereotactic products.

There are approximately 200,000 patients diagnosed with brain cancer each year in the United States. Epilepsy is estimated to affect an additional 3 million people in the United States, making it one of the most common neurological diseases.

The Integra NeuroSciences direct sales organization will sell the OCS2 Ojemann Cortical Stimulator in the US and internationally.
