Trimedyne Acquires License to New Diagnostic Device

Trimedyne has entered into a license agreement with Northwestern University, Evanston, Ill., for an exclusive license to the Hydrostat, a device that measures the resistance (opening pressure) of the sphincter valve of the esophagus.

Trimedyne has begun the development of a new, small laser and disposable fiber optic device to shrink the lower esophagus to tighten the sphincter and increase its resistance, preventing stomach acid from entering the esophagus. The Hydrostat shows the physician when the sphincter has been sufficiently tightened.

Trimedyne's laser procedure to treat gastroesophageal reflux disease is being designed for performance through a flexible endoscope on an outpatient basis. Clinical trials must be successfully concluded before an application to market Trimedyne's new laser, fiber optic device and the Hydrostat can be filed with the FDA.
