Hutchinson Technology Launches InSpectra™ StO₂ Tissue Oxygenation Monitor
HUTCHINSON, Minn., November 2, 2006 -- Hutchinson Technology Incorporated (Nasdaq/NMS: HTCH) today announced the product launch and European CE Mark of its new InSpectra™ StO₂ Tissue Oxygenation Monitor. [More]

Results of Multi-Site Clinical Study Confirm Utility of StO₂ Monitoring for Trauma Patients
HUTCHINSON, Minn.- October 2, 2006 - Hutchinson Technology Incorporated (Nasdaq/GS: HTCH) today announced results from its multi-site StO₂ Trauma Study. Data from the study show that local tissue oxygen saturation (StO₂) measured noninvasively on the thenar eminence (the muscle at the base of the thumb) is a statistically significant indicator of hypoperfusion (inadequate blood flow) in trauma patients. The study results were presented on September 29 by Stephen M. Cohn, M.D., at the annual meeting of the American Association for the Surgery of Trauma in New Orleans. [More]

Technology Receives FDA Clearance for InSpectra™ StO₂ Tissue Oxygenation Monitor
HUTCHINSON, Minn., July 20, 2006 -- Hutchinson Technology Incorporated (Nasdaq/NMS: HTCH) announced today that it has received clearance from the U.S. Food and Drug Administration (FDA) to begin marketing its InSpectra™ StO₂ Tissue Oxygenation Monitor. The patented device uses near infrared technology to noninvasively provide an absolute measurement of local tissue oxygen saturation (StO₂). The InSpectra StO₂ System is the only such device designed for clinical use in the trauma and emergency medicine settings. [More]

Hutchinson Technology BioMeasurement Division Announces Formation
of Trauma and Critical Care Advisory Board
HUTCHINSON, MN January, 14, 2004-- Hutchinson Technology Incorporated (NASDAQ/NMS: HTCH) announced today that its BioMeasurement Division has formed a Trauma and Critical Care Advisory Board to provide clinical guidance to the Division as it develops, documents clinical results, and introduces trauma and critical care applications of its InSpectra™ Spectrometer for noninvasive assessment of peripheral tissue oxygenation. [More]

The InSpectra™ StO₂ Tissue Oxygenation Monitor provides a direct, absolute measurement of hemoglobin oxygen saturation in tissue (StO₂), providing trauma teams the ability to measure tissue oxygenation and monitor it during resuscitation. It is the only tissue oxygenation monitor designed for trauma environments. The InSpectra StO₂ Tissue Oxygenation Monitor uses near infrared light to illuminate tissue, and then analyzes the returned light to produce a quantitative measurement of oxygen saturation in the tissue's microcirculation.

The StO₂ Trauma Study researched the role that tissue oxygen saturation monitoring could play in hemorrhagic shock and resuscitation. Study results demonstrate that StO₂ measurements less than 75% may indicate serious hypoperfusion in trauma patients and that StO₂ functions as well as base deficit in indicating hypoperfusion in trauma patients.
