Indications for Use

The Spectral MD DeepView system is intended for studies of blood flow in the microcirculation. The DeepView system is suitable for a wide variety of clinical applications including plastic surgery, diabetes, dermatology, vascular surgery, wound healing, neurology, neurosurgery and anesthetics.

Device Story

DeepView is a portable, non-contact imaging system for microcirculation blood flow assessment. It uses infrared light and non-contact Photoplethysmography (PPG) to detect pulsatile blood flow beneath the skin surface. The system consists of a mobile cart, laptop, mechanical arm, CMOS camera with DSP electronics, and disposable LED cartridges. It captures optical signatures, transforms them into 2D color images of relative perfusion distribution, and displays them to clinicians. Used in clinical settings (e.g., surgery, wound care), it allows non-invasive visualization of blood flow without ionizing radiation. Clinicians use these images to assess tissue perfusion, aiding in clinical decision-making for various surgical and medical conditions.

Clinical Evidence

Bench testing only. Direct comparison testing performed against moorLDI and Avant 9600 predicates. Testing included camera distance and tissue phantom studies to demonstrate equivalence in detecting pulse frequency and producing relative blood flow images.

Technological Characteristics

Non-contact Photoplethysmography (PPG) using infrared LED illumination. System includes CMOS camera, DSP electronics, mobile cart, and laptop. Provides 2D color images of relative perfusion. Software-controlled data collection and analysis. Non-invasive, no ionizing radiation.

Indications for Use

Indicated for studies of blood flow in the microcirculation across clinical applications including plastic surgery, diabetes, dermatology, vascular surgery, wound healing, neurology, neurosurgery, and anesthetics.

Regulatory Classification

Identification

An extravascular blood flow probe is an extravascular ultrasonic or electromagnetic probe used in conjunction with a blood flowmeter to measure blood flow in a chamber or vessel.

Summary of Technological Characteristics:

The DeepView uses infrared light to detect pulsatile blood flow in patients, and then provides 2D color images of relative perfusion distribution to healthcare providers. The technology used is non contact Photoplethysmography (PPG). PPG allows the DeepView to take advantage of the deep penetration of near IR light in human tissue.

The DeepView, as well as all three predicate devices, is portable and use software to control the device operations, collect the patient data, analyze the data, present the data to the user, etc. The DeepView displays 2D color images demonstrating relative blood flow, similar to the moorLDI and moorLD12-1R predicate devices. The new device and the three predicate devices can all store patient data, which can then be examined later by healthcare professionals.

The DeepView and the moorLDI and moorLDI2-IR are non-contact regarding patient interaction. All devices (new and predicate) require light and optics for detection of blood flow. The two predicate imaging devices (moorLDI and moorLD12-1R) use laser illumination, while the DeepView device and predicate Avant 9600 device use LED illumination.

Summary of Test Data:

Direct comparison testing was performed with both the moorLDI and Avant 9600 predicates. Comparison testing was conducted to demonstrate that the DeepView can, using optical methods, detect blood flow and pulse pressure. Using these attributes, DeepView was tested alongside the predicate devices to show substantial equivalence in detecting pulse frequency and in producing flow images. Comparison testing included camera distance testing and tissue phantom testing.

The comparison testing conducted demonstrates that the DeepView is substantially equivalent to the predicate devices identified and does not introduce any new issues of safety and efficacy.

Conclusion:

Spectral MD™, Inc. considers the DeepView to be substantially equivalent to the predicate devices listed above This conclusion is based on the similarities in primary intended use, principles of operation, functional design, and established medical use.
