Treating Untreatable Brain Tumors: FDA Approves New Laser Surgery

Monteris Medical Earns 510(k) Clearance for AutoLITT(TM)

KALAMAZOO, Mich., and WINNIPEG, Manitoba, May 13 /PRNewswire/ -- An MRI-guided
laser surgery method, in investigational use at both The Cleveland Clinic and
University Hospitals Case Medical Center, holds promise for thousands of brain
tumor patients and has earned clearance from the Food and Drug Administration
(FDA) for use in neurosurgery. The first applications of the technology are
expected to be for the treatment of otherwise inoperable brain tumors.

The AutoLITT System uses an MRI-guided laser probe, passed through a small bur
hole in the skull, to deliver laser interstitial thermal therapy ("LITT") to
heat and coagulate the tumor from the inside. High-intensity laser energy is
applied directly to the tumor, rather than passing through normal tissue,
while the MRI measures the temperature inside the brain, showing thermal
damage as it happens and facilitating precise control of the treatment. Once
coagulated, the treated tumor mass is dead.

"The AutoLITT procedure delivers new-found hope for patients who have
previously been given limited options in the treatment of their tumors,"
explains James Duncan, president and CEO of Monteris Medical, the AutoLITT
manufacturer. The system offers a potential option for patients with tumors
that are too difficult or too risky to treat, tumors that don't respond to
other treatments, and tumors in patients that are otherwise not good
candidates for surgery or radiosurgery.
