Intended Use
The Clear Guide SCENERGY is software that provides fusion of images from Computed Tomography (CT), Magnetic Resonance (MR), and Ultrasound (US) modalities. US images can be fused with either CT or MR. The Clear Guide SCENERGY utilizes the Clear Guide CORE and Clear Guide SuperPROBE platform to display images of the target regions and the projected path of the interventional instrument, while taking into account patient movement and deformation. Instrumentation used with the Clear Guide SCENERGY might include an interventional needle or needle-like rigid device, such as a biopsy needle, an aspiration needle, or an ablation needle. The device is intended to be used in any interventional or diagnostic procedure where the combination of these modalities is used for visualization, except for procedures on the brain. The device is intended for use in a clinical setting, in patients of sufficient size (at least 25 kg).
Device Description
The Clear Guide SCENERGY guidance system is intended to be an accessory to existing ultrasound imaging systems, to provide image fusion, instrument tracking, and image/instrument guidance functionality to operators during image-guided medical interventions that utilize data from multiple modalities (e.g., ultrasound and computed-tomography (CT), ultrasound and magnetic resonance (MR)). The Clear Guide SCENERGY uses optical detection technology to identify and track objects in the field of view. By pairing this information with the aforementioned imaging data, the Clear Guide SCENERGY executes proprietary software algorithms to display fused images in real-time to the clinician. These segmentation and registration algorithms are automated. Segmentation results are deterministic, meaning that new inputs (e.q., new CT or MR) would be required to change the segmentation output. Registration can be reset by the user at any time during use.
More Information

Not Found

No
The description mentions "proprietary software algorithms" for segmentation and registration, and states that segmentation results are "deterministic." There is no mention of learning, training data, or adaptive algorithms, which are characteristic of AI/ML.

No.
The device is a software for image fusion and guidance during interventional procedures, not a device that directly treats a condition or disease.

No
The device is described as an accessory for image guidance during interventional or diagnostic procedures, providing image fusion and instrument tracking. It does not perform a diagnosis itself, but rather aids in visualization for procedures that may be diagnostic.

No

The device description explicitly states that the Clear Guide SCENERGY uses "optical detection technology to identify and track objects in the field of view," indicating the presence of hardware components beyond just software.

Based on the provided information, the Clear Guide SCENERGY is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
  • Clear Guide SCENERGY's Function: The Clear Guide SCENERGY is a software and hardware system that provides image fusion, instrument tracking, and guidance during medical interventions. It works with existing imaging modalities (CT, MR, US) and physical instruments (needles) to assist clinicians in visualizing and navigating within the patient's body.
  • No Specimen Analysis: The device does not involve the analysis of any biological specimens taken from the patient. Its function is entirely focused on image processing, tracking, and guidance within the living patient.

Therefore, the Clear Guide SCENERGY falls under the category of a medical device used for image-guided procedures, not an In Vitro Diagnostic device.

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

Software Verification and Validation Testing: Conducted as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." Software considered "moderate" level of concern.
Segmentation Testing: Automatic segmentation of fiducial markers by the Clear Guide SCENERGY was evaluated by comparing software outputs to manual selection in phantom datasets.
Fusion Testing: Clear Guide SCENERGY's ability to provide fused images from ultrasound and CT/MR modalities was evaluated using fusion testing. Fusion quality was assessed by taking distance measurements between identifiable landmarks or surfaces seen on ultrasound and CT, or ultrasound and MR. This metric is known as Tissue Registration Error (TRE).
Systematic Error (Tip-to-Tip) Testing: Defined as the cumulative error within the entire system (segmentation, registration, fusion, and guidance errors). Metric is a "tip-to-tip" distance from the needle point seen by ground truth CT (or MR) to the same needle point seen by Clear Guide SCENERGY's displayed guidance. Phantom datasets were utilized for this evaluation.
Clinical Testing: A small safety study was run to demonstrate that the Clear Guide SCENERGY could be utilized safely in pediatric patients without creating new or different questions of safety or effectiveness. The study included patients ranging in age (5 to 17) and weight (11.9 to 78.9 kg) to demonstrate use in children and adolescents.
Key Results: Performance data demonstrates that the product accurately achieves its intended use and is as safe and as effective as the predicate device. The Clear Guide SCENERGY is substantially equivalent to its predicate device.

Performance Data

Performance testing of the Clear Guide SCENERGY device demonstrates that the product accurately achieves its intended use. Results of performance testing show that the subject device is as safe and as effective as the predicate device.

Software Verification and Validation Testing

Software verification and validation testing were conducted, and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for the Clear Guide SCENERGY was considered as a "moderate" level of concern, since a failure or latent flaw in the software could directly result in minor injury to the patient or operator, or indirectly result in minor injury to the patient or operator through incorrect or delayed information or through the action of a care provider.

Segmentation Testing

The automatic segmentation of fiducial markers by the Clear Guide SCENERGY was evaluated by comparing software outputs to manual selection in phantom datasets.

Fusion Testing

The Clear Guide SCENERGY's ability to provide fused images from ultrasound and CT/MR modalities was evaluated using fusion testing. Fusion quality was assessed by taking distance measurements between identifiable landmarks or surfaces seen on ultrasound and CT, or ultrasound and MR. This metric is known as Tissue Registration Error (TRE).

Systematic Error (Tip-to-Tip) Testing

Systematic error in the Clear Guide SCENERGY is defined as the cumulative error that would be observed within the entire system, which includes segmentation, registration, fusion, and guidance errors. This performance metric is a "tip-to-tip" distance from the needle point seen by ground truth CT (or MR) to the same needle point seen by Clear Guide SCENERGY's displayed quidance. This metric has been called "tracking error" in literature for the predicate device. Phantom datasets were utilized for this evaluation.

Clinical Testing

A small safety study was run to demonstrate that the Clear Guide SCENERGY could be utilized safely in pediatric patients without creating new or different questions of safety or effectiveness. The study included patients ranging in age (5 to 17) and weight (11.9 to 78.9 kg) to demonstrate use in children and adolescents.

Conclusions

The Clear Guide SCENERGY has the same intended use as the predicate device, with a minor change to its indications for use. There are no differences in the product's feature offerings (from the predicate device), and therefore no new or different questions of safety or effectiveness are raised. Additionally, performance tests confirm that the Clear Guide SCENERGY is as safe and as effective as the predicate device for the intended patient population. Therefore, the Clear Guide SCENERGY is substantially equivalent to its predicate device.
