Intended Use

The IntraSight system is used for the qualitative and quantitative evaluation of vascular morphology in the coronary arteries and vessels of the peripheral vasculature. It is also indicated as an adjunct to conventional angiographic procedures to provide an image of vessel lumen and wall structures. ChromaFlo is indicated for qualitative blood flow information from peripheral and coronary vasculature; flow information can be an adjunct to other methods of estimating blood flow and blood perfusion. The pressure feature is intended for use in all blood vessels, including coronary and peripheral arteries, to measure intravascular blood pressure during diagnostic angiography and/or interventional procedures. Rotational 45MHz feature is intended for the qualitative and quantitative evaluation of vascular morphology in the coronary arteries and vasculature. As an adjunct to conventional angiographic procedures to provide an image of the vessel lumen and wall structures. The pullback feature of the Spinvision (PIMr) withdraws the imaging core within the protective sheath for a maximum of 15 cm. The FFR Modality is indicated in all blood vessels, including coronary and peripheral arteries, to measure intravascular blood pressure during diagnostic angiography and/or interventional procedures. The iFR Modality is intended to be used in conjunction with currently marketed Volcano pressure wires. In the coronary anatomy, the iFR modality has a diagnostic cut- point of 0.89 which represents an ischemic threshold and can reliably guide revascularization decisions during diagnostic catheterization procedure. When used as for a pullback assessment, the iFR modality is intended as a visual aid in decision making by indicating the relative location and severity of the stenoses such as, multiple lesions or diffuse disease.

Device Story

IntraSight Mobile is a cart-based system for intravascular ultrasound (IVUS) imaging and pressure measurement in coronary/peripheral vasculature. System interfaces with Volcano IVUS catheters and pressure wires via Patient Interface Module (PIM). IVUS mode: transducer emits/receives high-frequency sound waves; system processes signals to generate 360° cross-sectional tomographic images. Pressure mode: acquires intraluminal pressure data from guide wires and aortic pressure from cath lab equipment. Used in cath labs by physicians/technicians. Mobile cart design includes touch screen panel PC and ruggedized secondary controller housing. Output provides visual assessment of vessel lumen/wall structures, blood flow, and pressure metrics to guide clinical decision-making during interventions.

Clinical Evidence

Bench testing only. Performance data included EMC and electrical safety testing, environmental testing, design verification, software verification and validation, packaging validation, simulated use/usability validation, and image validation. All acceptance criteria were met.

Technological Characteristics

Ultrasonic pulsed echo imaging system; 45MHz rotational imaging capability. Interfaces with IVUS catheters and pressure wires via PIM. Mobile cart form factor with touch screen panel PC and ruggedized controller housing. Software-based signal processing for image reconstruction and pressure analysis. Complies with electrical and physical safety standards.

Indications for Use

Indicated for patients undergoing diagnostic angiography or interventional procedures in coronary and peripheral vasculature. Used for qualitative/quantitative evaluation of vascular morphology, blood flow/perfusion assessment (ChromaFlo), and intravascular blood pressure measurement (FFR/iFR modalities). iFR modality indicated for coronary anatomy to guide revascularization decisions at 0.89 ischemic threshold.

Regulatory Classification

Identification

This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Special Controls

*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

### DEVICE DESCRIPTION:

The IntraSight Mobile System provides qualitative and quantitative evaluation of vascular morphology in the coronary arteries and peripheral vasculature. It is also indicated as an adjunct to conventional angiographic procedures to provide an image of vessel lumen and wall structures. The IntraSight Mobile System interfaces with Volcano Intravascular Ultrasound (IVUS) Imaging Catheters and pressure wires.

When operating in the IVUS mode, the IVUS catheter uses a transducer near the distal tip to emit and receive high frequency sound waves. The system is then able to analyze the signal that is received by the transducer to differentiate between vessel structures and produce a

360° cross-sectional, tomographic image. When operating in the pressure mode, the system acquires intraluminal data from pressure guide wire while simultaneously taking aortic pressure data from the established catheterization lab equipment. Catheters and guide wires are connected to the system via the Patient Interface Module (PIM).

### SUBSTANTIAL EQUIVALENCE:

The IntraSight Mobile System is a modification to the currently marketed IntraSight System cleared under K190078. The purpose of the modification is to provide the cath lab integrated system functionality on a light-weight mobile cart. The functionality of the system remains the same and is now available in a mobile version with a touch screen on the panel PC. For additional protection of the secondary controller, a rugged housing has been added that can be attached to the cart or to the bedside.

The logo is simple and modern, and the colors are clean and professional.

None of the modifications effect or alter the fundamental scientific technologies of the currently marketed device.

The proposed IntraSight Mobile System has the following similarities to the currently marketed IntraSight System:

- same intended use and operating principle ●
- have the same Indications for Use ●
- incorporates the same basic design for image acquisition, measurements, and archiving
- incorporates the same basic materials ●
- uses the same Patient Interface Modules, and the same compatible catheters and pressure wires
- uses the same software platform and user interface
- is designed and manufactured to the same electrical and physical safety standards

### PERFORMANCE DATA:

Performance testing completed for a determination of substantial equivalence included the following:

- EMC and Electrical Safety Testing ●
- Environmental Testing
- Design Verification
- Software Verification and Validation
- Packaging Validation ●
- Simulated Use / Usability Validation ●
- Image Validation

### CONCLUSION:

All device acceptance criteria were met. Results of testing show that the proposed IntraSight Mobile System meets its intended use. The differences between the subject device and predicate device do not raise new questions of safety and/or effectiveness. Therefore, the proposed IntraSight Mobile System is substantially equivalent to the predicate IntraSight System.
