Intended Use
The Ox-Imager CS™ is indicated for use to determine oxygenation levels in superficial tissues for patients with potential circulatory compromise.
Device Description
The Ox-Imager CSTM is intended for use by healthcare professionals as a noninvasive tissue oxygenation measurement system that maps value of: oxygen saturation, oxy-hemoglobin, and deoxy-hemoglobin into 2D/3D visual presentations. The Ox-Imager™ CS is a non-contact imaging device to visualize spatially-resolved optical and functional parameters of biological tissue. The Ox-Imager CS shares fundamental principles with other oximeters and tissue oxygenation measurement systems. Spectral analysis is used to measure oxygen saturation (StO2), oxyhemoglobin (HbO2), deoxyhemoglobin (HbR) and determine tissue optical properties (absorption and scattering) using specific LED wavelengths and patterns. The Ox-Imager CS uses both visible (VIS) and near infrared (NIR) wavelengths; other systems that also measure oxygenation levels in superficial tissue may use only VIS or NIR wavelengths. Tissue oximetry exposes tissue to optical radiation of known wavelengths and captures the remitted light or reflectance. The remitted back scattered light is then used to calculate the tissue constituents mentioned above based on principles of multispectral imaging and Spatial Frequency Domain Imaging (SFDI).
More Information

No
The description focuses on established optical principles (multispectral imaging, SFDI) and spectral analysis for calculating oxygenation parameters, without mentioning AI/ML algorithms.

No

The device is indicated for determining oxygenation levels, which is a diagnostic function, not a therapeutic intervention.

Yes

Explanation: The device is indicated for use to determine oxygenation levels in superficial tissues for patients with potential circulatory compromise, which is a diagnostic purpose. It measures and presents values of oxygen saturation, oxy-hemoglobin, and deoxy-hemoglobin to assess these levels.

No

The device description explicitly states it is a "non-contact imaging device" that uses "specific LED wavelengths and patterns" and "captures the remitted light or reflectance," indicating the presence of hardware components for light emission and detection.

Based on the provided information, the Ox-Imager CS™ is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze specimens derived from the human body. The Ox-Imager CS™ is a non-contact imaging device that measures oxygenation levels in superficial tissues in vivo (on the living patient). It does not analyze blood, urine, tissue samples, or any other specimen taken from the body.
  • The device description explicitly states it's a "noninvasive tissue oxygenation measurement system." This reinforces that it's used directly on the patient's tissue, not on a sample.
  • The intended use is to "determine oxygenation levels in superficial tissues for patients with potential circulatory compromise." This is a direct measurement on the patient, not an analysis of a specimen.

Therefore, the Ox-Imager CS™ falls under the category of a non-invasive diagnostic device used for in vivo measurements, not an In Vitro Diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

  • Clinical Study: compared the Ox-Imager CS to the predicate device, HyperMed OxyVu-1. The objective was to establish substantial equivalence. Circulatory compromise was mimicked by performing a vascular occlusion test using both devices to determine if there was a statistically significant decrease in tissue oxygen saturation (StO2) between baseline and compromised tissue states. It was demonstrated that the predicate OxyVu-1 and the Ox-Imager CS recover highly correlated values of StO2 during the time course of a vascular occlusion test and that both devices measured a statistically significant decrease in tissue oxygen saturation (StO2) after circulatory compromise.
  • Blood Phantom Desaturation Study: conducted to correlate changes in tissue oxygen saturation (StO2) to pO2. The pO2/StO2 curves showed strong agreement with expected StO2 values.
  • Pre-clinical Study: conducted in rabbits that correlated co-oximeter values (SaO2/SvO2) from blood draws to tissue oxygen saturation (StO2) during an inspired oxygen challenge. Results showed a strong linear and monotonic relationship between blood gas values and Ox-Imager CS measurements as fraction of inspired oxygen (FiO2) was changed.
  • Clinical Study: compared tissue oxygen saturation values (StO2) to transcutaneous oxygen measurements (tcpO2) during a vasculature occlusion test meant to mimic transient ischemia. Average values at baseline and at the end of occlusion (tissue compromise state) were compared to determine sensitivity to circulatory compromise. The shape of both curves during transient ischemia matched literature and there was a significant change in both StO2 and tcPO2 values between baseline and tissue compromise timepoints.

Device Description

The Ox-Imager CSTM is intended for use by healthcare professionals as a noninvasive tissue oxygenation measurement system that maps value of: oxygen saturation, oxy-hemoglobin, and deoxy-hemoglobin into 2D/3D visual presentations. The Ox-Imager™ CS is a non-contact imaging device to visualize spatially-resolved optical and functional parameters of biological tissue. The Ox-Imager CS shares fundamental principles with other oximeters and tissue oxygenation measurement systems. Spectral analysis is used to measure oxygen saturation (StO2), oxyhemoglobin (HbO2), deoxyhemoglobin (HbR) and determine tissue optical properties (absorption and scattering) using specific LED wavelengths and patterns. The Ox-Imager CS uses both visible (VIS) and near

infrared (NIR) wavelengths; other systems that also measure oxygenation levels in superficial tissue may use only VIS or NIR wavelengths. Tissue oximetry exposes tissue to optical radiation of known wavelengths and captures the remitted light or reflectance. The remitted back scattered light is then used to calculate the tissue constituents mentioned above based on principles of multispectral imaging and Spatial Frequency Domain Imaging (SFDI).

Intended Use

The Ox-Imager CS™ system is intended for use by healthcare professionals as a non-invasive tissue oxygenation measurement system that reports an approximate value of:

  • Oxygen Saturation (StO2)
  • -Oxy-hemoglobin (HbO2), and
  • Deoxy-hemoglobin (HbR) -

in superficial tissue.

Indications for Use
