The InSpectra™ Tissue Spectrometer with 12 to 25 mm probes is indicated for use in monitoring patients during circulatory or perfusion examinations of skeletal muscle or when there is a suspicion of compromised circulation. The InSpectra™ Tissue Spectrometer System is intended to noninvasively and continuously measure hemoglobin oxygen saturation: in the upper extremity, shoulder, or lower extremity with 12 mm to 25 mm probes. The value of these measurements in disease states has not been demonstrated. ## Device Story InSpectra™ Tissue Spectrometer System (Model 325) estimates percent hemoglobin oxygen saturation (StO2) in tissue to reflect localized perfusion. System components include monitor (user interface/electronics), optical integrator (patient cable), OptoShield™ disposable adhesive pad, thermal printer, and Optolink™ RS232 optical-to-electrical converter. New software allows PC-based viewing, storage, and charting of StO2 data via one-way communication from monitor to PC. Used in clinical settings for continuous monitoring; provides time-trending and recording. Healthcare providers use output to assess perfusion status; clinical utility in specific disease states not demonstrated. ## Clinical Evidence Bench testing only. Verification testing confirmed that the new software meets or exceeds all predetermined specifications. ## Technological Characteristics Non-invasive tissue spectrometer; uses optical sensing via 12-25 mm probes. Components: monitor, optical integrator, adhesive patient interface, RS232 optical converter, thermal printer. Connectivity: one-way data transfer from monitor to PC via RS232. Software: PC-based application for data visualization and charting. ## Regulatory Identification An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter. ## Predicate Devices - InSpectra™ Tissue Spectrometer System, Model 325 ([K012759](/device/K012759.md)) ## Reference Devices - Hutchinson Technology, Inc.

This value is a reflection of localized perfusion of that tissue. The InSpectra™ is composed of the following components. Hutchinson Technology, Inc. {1}------------------------------------------------ - Monitor: The "InSpectra Tissue Spectrometer" houses the user interface, and associated electronics. It serves as the analytical and display instrument. - Patient Cable: The "Optical Integrator" transmits light to and from the Tissue Spectrometer and the patient; - 미 Patient Interface: The "OptoShield™" interface is a disposable pad that mechanically attaches to the distal end of the Optical Integrator. Its bottom has an adhesive backing for attachment to the patients skin for continuous monitoring. Until ready for use, the adhesive is covered with a liner to allow intermittent measurements. - Printer: A "Thermal Printer" may be used to print out the StO2 results for time trending and recording purposes. - Optical Converter: An "Optolink™" RS232 Optical Converter -■ Model 300 is a device that converts the optical output of the Spectrometer to an electrical signal. - Set-up Accessories: A "System Check™" module with both "High" ■ and "Low" "Single Point References" are provided to verify proper system operation. - . Inspectra System Software: Software provided on a compact disk for use on a personal computer that displays data from the tissue spectrometer on a computer during a live session or from an encrypted data file. ## Intended Use: Technology Incorporated's InSpectra™ Hutchinson Tissue Spectrometer System, Model 325. is a non-invasive monitoring system that measures an approximated value of percent hemoglobin oxygen saturation in tissue (StO2). The InSpectra™ Tissue Spectrometer with 12 to 25 mm probes is indicated for use in monitoring patients during circulatory or perfusion examinations of skeletal muscle or when there is a suspicion of compromised circulation. The InSpectra™ Tissue Spectrometer System is intended to noninvasively and continuously measure hemoglobin oxygen saturation: in the upper extremity, shoulder, or lower extremity with 12 mm to 25 mm probes. The value of these measurements in disease states has not been demonstrated. {2}------------------------------------------------ ## Technological Characteristics: The modified device has the same basic technological characteristics as the predicate device. The modification includes: New software provided via compact disk that can be downloaded onto a personal computer. The software enables the user to view, store and chart the output measurement of the Inspectra System. The software does not alter the information already displayed on the predicate device. There is a one-way communication from the monitor to the user PC. ## Substantial Equivalence Rationale: HTI believes that the modified device is substantially equivalent to the unmodified predicate device. The unmodified device already provides the capability to display information through its output device (Optolink) to a thermal printer. The predicate to our unmodified Inspectra device was the Hutchinson Technology, Inc. Biospectrometer NB Model 1111, FDA control # K963903. The Biospectrometer used a laptop personal computer for the primary display of StO2 and other output information including date and time, and allowed the data to be marked, saved and charted. ## Test Conclusions: Hutchinson Technology, Inc. has conducted extensive testing of the new Inspectra™ Software to verify adherence to requirements. All test results verify that the software meets or exceeds all predetermined specifications. {3}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
