This is performed in medical environments including physician offices, hospitals, ambulatory care and Emergency Medical Services. The ODISsey Tissue Oximeter is indicated for use in monitoring patients during circulatory or perfusion examinations of skeletal muscle or when there is a suspicion of compromised circulation. ## Device Story ODISsey Tissue Oximeter is an optical device for non-invasive estimation of percent oxygen saturation (StO2) in tissue volumes. Device uses near-infrared technology to measure tissue oxygenation; provides real-time StO2 values. Used in hospitals, physician offices, ambulatory care, and EMS settings by clinicians. Output allows assessment of tissue perfusion and oxygen delivery; aids in identifying compromised circulation. Benefits include non-invasive monitoring of skeletal muscle perfusion. ## Clinical Evidence No human clinical data provided. Performance validated via animal study using three dog limbs perfused with an extracorporeal blood circulation system. StO2 values compared against a Radiometer OSM3 Hemoximeter (gold standard) and the Hutchinson InSpectra Tissue Spectrometer. Results demonstrated excellent correlation with both comparators. ## Technological Characteristics Near-infrared tissue oximeter; non-invasive optical sensing principle. Complies with electrical safety, laser safety, and electromagnetic compatibility requirements. Form factor designed for clinical environments. Connectivity and software details not specified. ## 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)) - InSpectra Tissue Spectrometer System, Model 325 ([K023938](/device/K023938.md)) - Biospectrometer NB Oximeter Model 1111 ([K963903](/device/K963903.md)) ## Reference Devices - Radiometer OSM3 Hemoximeter (CO-Oximeter) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Oximeter Description of the device: The ODISsey Tissue Oximeter is an optically based device that noninvasively estimates the percent oxygen saturation (StO2) in a volume of tissue underneath the sensor. {1}------------------------------------------------ Indications: The ViOptix ODISsey Tissue Oximeter is intended to non-invasively estimate the percent oxygen saturation (StO2) in a volume of tissue. This is performed in medical environments including physician offices, hospitals, ambulatory care and Emergency Medical Services. The ODISsey Tissue Oximeter is indicated for use in monitoring patients during circulatory or perfusion examinations of skeletal muscle or when there is a suspicion of compromised circulation. Summary of the technological characteristics of our device compared to the predicate device: ### Technological Characteristics The technological characteristics of the ODISsey ™ Tissue Oximeter, Model Oxy-2 are similar to those of the cited predicate devices, as well as similar devices based on near-infrared technology. These devices are equivalent in terms of design, functionality, principles of operation, performance specifications and indications for use. When compared to the predicate device, ODISsey ™ Tissue Oximeter, Model Oxy-2 does not raise new technological issues. #### Indications for Use . Oximeters and perfusion monitors are used to measure oxygen saturation in the arteries or tissues, or to assess the amount of oxygen delivered to the tissues. Substantial equivalence for the ODISsey ™ Tissue Oximeter, Model Oxy-2 is supported by the predicate devices with identical indications for use. ### Performance Testing Bench testing, biocompatibility testing, and animal studies, were performed to demonstrate the product functions as intended. The ODISsey ™ Tissue Oximeter, Model Oxy-2 is designed to comply with the requirements of electrical safety, laser safety, and electromagnetic compatibility requirements. ### Animal Testing The ViOptix ODISsey™ Tissue Oximeter product performance was evaluated against a "gold standard" CO-Oximeter and a FDA cleared predicate device from Hutchinson Testing was performed by measuring tissue oxygen saturation (StO2) on three dog limbs surgically removed and perfused with an extracorporeal blood circulation system. Oxygen perfusion was controlled and monitored by {2}------------------------------------------------ a Radiometer OSM3™ Hemoximeter (CO-Oximeter). The ViOptix StO2 values were then compared with those from the CO-Oximeter and a Hutchinson's InSpectra™ Tissue Spectrometer. These results show excellent correlation with both the "gold standard" and the predicate device. ## CONCLUSION Based on the design, technology, performance and functional testing, intended use, and clinical evaluation, the ODISsey ™ Tissue Oximeter, Model Oxy-2 is substantially equivalent to the devices currently marketed under the Federal Food, Drug and Cosmetic Act. The ODISsey ™ Tissue Oximeter, Model Oxy-2 raises no new issues of safety or effectiveness. Therefore, safety and effectiveness are reasonably assured, and substantial equivalence is supported, justifying 510(k) clearance of the ODISsey ™ Tissue Oximeter, Model Oxy-2. {3}------------------------------------------------ Public Health Service Image /page/3/Picture/2 description: The image is a circular seal or logo.
