May 1, 2007 - Hemedex Inc., a privately-held Cambridge, MA medical device company, announced that it has reached an agreement with Codman & Shurtleff Inc. to distribute the only minimally invasive device that can measure cerebral blood flow and cerebral tissue perfusion in absolute units, in real time.

Cerebral tissue perfusion, the rate at which blood is replenished at the capillary level, is the primary factor in the transport of oxygen and nutrients to the brain. Adequate cerebral tissue perfusion is an essential requirement to maintain brain function.

The Hemedex QFlow 500 Perfusion Probe is placed into targeted cerebral tissue where it responds rapidly to changes in cerebral perfusion, allowing clinicians to quickly individualize therapy. The probe is connected to the Bowman Perfusion Monitor which calculates, stores and displays the perfusion data.

Clinical data suggests this technology may help doctors better identify and manage those patients at risk for complications from stroke, traumatic brain injury and subarachnoid hemorrhage due to decreased cerebral blood flow by providing continuous, real-time, soft-tissue perfusion measurements in absolute units.
