Intended Use
Upon intravenous administration of SPY AGENT™ GREEN (Indocyanine green for injection, USP) the SPY-PHI System is used with SPY AGENT™ GREEN to perform intraoperative fluorescence angiography. The SPY-PHI System is indicated for use in adult and pediatric patients one month of age and older. The SPY-PHI System is indicated for fluorescence imaging of blood flow and tissue perfusion before, during, and after: vascular, gastrointestinal, organ transplant, and plastic, micro- and reconstructive surgical procedures.
Device Description
The SPY-PHI System is an imaging system used in capturing fluorescent images for the visual assessment of blood flow, as an adjunctive method for the evaluation of tissue perfusion, and related tissuetransfer circulation for use in imaging during various surgical procedures. The SPY-PHI System consists of the following main components: Imaging Head/ Imager (HH9030) with an integrated light guide cable and the Video Processor/Illuminator (VPI) (PC9001). Indocyanine green (ICG) is injected intravenously into the patient. The Imaging Head may be either handheld or attached to a mechanical arm and provides illumination of the regions of a patient's body to be observed with near infrared laser light to excite ICG fluorescence. Alternatively, the Imaging Head provides white light illumination of the regions of a patient's body to be observed for color imaging. A CMOS camera in the Imaging Head captures the fluorescent image under laser illumination or a color image under white light illumination. The VPI receives the video signal from the Imaging Head and processes and outputs the video image to a medical grade video monitor and/or video recorder. Adjustments to the operation of the SPY-PHI System are possible through switches at either the Imaging Head or the VPI.
More Information

No
The description focuses on standard imaging and video processing technology, with no mention of AI, ML, or related concepts.

No
The device is an imaging system intended for diagnostic purposes (visual assessment of blood flow and tissue perfusion) and does not directly provide therapy.

Yes

The device performs intraoperative fluorescence angiography for the visual assessment of blood flow and tissue perfusion, which are used to evaluate the physiological state for surgical procedures.

No

The device description explicitly states that the SPY-PHI System consists of hardware components, including an Imaging Head/Imager and a Video Processor/Illuminator.

Based on the provided information, the SPY-PHI System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: An IVD device is used to examine specimens derived from the human body (like blood, urine, or tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
  • SPY-PHI System Function: The SPY-PHI System is an in vivo imaging system. It is used to visualize blood flow and tissue perfusion within the patient's body during surgical procedures. It uses a fluorescent agent (ICG) injected intravenously into the patient and then images the fluorescence emitted from within the patient's tissues.

The device description and intended use clearly indicate that the SPY-PHI System is used for direct imaging of the patient's body during surgery, not for testing samples outside the body.

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

Safety and effectiveness of the SPY-PHI System for its intended use in the visualization of blood flow and tissue perfusion during various surgical procedures was assessed through a series of clinical literature evaluations to support the expansion to the cleared indications for use, including published literature references to support the expansion of existing indications for use to include pediatric patients, one (1) month of age and older.

Efficacy data obtained from published literature showed successful visualization in majority of the studies. Analysis of ICG doses administered to several pediatric subpopulations showed that the effective doses used in angiographic applications were similar to those administered to adult patients. Based on anecdotal clinical experience, lower doses of ICG may be effective, especially in younger patients and those with lower body weight.

None of the published literature identified anaphylaxis or any other adverse events related to SPY fluorescence imaging with ICG in pediatric patients. Overall the data suggests that there are no differences in safety and efficacy of SPY fluorescence imaging with ICG between pediatric patients (aged 1 month to 21 years) and adult patients.

Performance Testing of the SPY-PHI System:

The SPY-PHI System was designed and developed by Novadaq Technologies Inc. in accordance with the applicable requirements and standards to establish performance and safety of the device's safety and performance were verified by tests conducted by Novadag and accredited third-party laboratories.

SPY-PHI was tested and determined to be in conformance with IEC 60601-1:2006 Medical Electrical Equipment – Part 1: General requirements for basic safety and essential performance, IEC 60601-1-2 (4th edition) and IEC 60825:2007 Safety of laser products -- Part 1: Equipment classification and requirements.

An assessment of the SPY-PHI system software was conducted to demonstrate conformance with the applicable requirements of IEC 62304:2006 Medical device software - Software life-cycle processes. It has been demonstrated that all processes and activities necessary for the safe design and maintenance of SPY-PHI software are performed in accordance with the standard.

Clinical Summary and Use in Pediatric Patients:

Safety and effectiveness of the SPY-PHI System for its intended use in the visualization of blood flow and tissue perfusion during various surgical procedures was assessed through a series of clinical literature evaluations to support the expansion to the cleared indications for use, including published literature references to support the expansion of existing indications for use to include pediatric patients, one (1) month of age and older.

Efficacy data obtained from published literature showed successful visualization in majority of the studies. Analysis of ICG doses administered to several pediatric subpopulations showed that the effective doses

used in angiographic applications were similar to those administered to adult patients. Based on anecdotal clinical experience, lower doses of ICG may be effective, especially in younger patients and those with lower body weight.

None of the published literature identified anaphylaxis or any other adverse events related to SPY fluorescence imaging with ICG in pediatric patients. Overall the data suggests that there are no differences in safety and efficacy of SPY fluorescence imaging with ICG between pediatric patients (aged 1 month to 21 years) and adult patients.

Conclusion & Summary of Substantial Equivalence

Based on the information presented in this Traditional 510(k) premarket notification, and based on the fundamental scientific technological characteristics, principle of operation, intended use, environment of use, and indications for use, the SPY-PHI System has been determined to be substantially equivalent to the predicate devices, the SPY Portable Handheld Imaging (SPY-PHI) System (FDA 510(K)cleared in K162885 and K190729) and the SPY Elite Intraoperative Perfusion Assessment System (FDA 510(k)-cleared in K182907)

Any minor technological or design differences between the SPY-PHI System and the predicate devices do not raise any questions related to safety or effectiveness. The proposed additional/expanded indications for use do not raise any issues related to safety or effectiveness for this device-drug combination product.
