IntraSight Plus is a multi-function system intended to be used as an adjunct diagnostic tool for qualitative and quantitative evaluation of vascular morphology in coronary arteries and peripheral vasculature in patients eligible for endovascular procedures.

The system, when configured with optional features, can also be used for:

quantitative evaluation of coronary physiology using pressure-derived ratios,
quantitative evaluation of coronary artery dimensions,
enhanced visualization of stent or balloon placement in coronary arteries, and
co-registration of an x-ray image with coronary intravascular ultrasound and/or coronary pressure-derived ratios

in patients eligible for percutaneous coronary intervention.

The IntraSight Plus IVUS function is indicated for use in patients undergoing conventional angiographic procedure to assess vascular morphology and to assess the need for additional treatment post percutaneous intervention. IVUS is obtained with a compatible ultrasound catheter and used as an adjunct to examine vascular morphology in the coronary arteries and vessels of the peripheral vasculature.

The IntraSight Plus FFR and iFR functions are indicated for use in patients with signs of coronary artery disease undergoing coronary catheterization procedures to assess the hemodynamic significance of coronary lesions that may contribute to myocardial ischemia. FFR and iFR are obtained with a compatible pressure guide wire.

following:

Software
Cybersecurity
Interoperability
Electromagnetic compatibility
Electrical, mechanical, and thermal safety
Usability
Packaging validation

Clinical Testing:

Not Applicable – IntraSight Plus has the same intended use and indications for use as the predicate devices. Differences in technological characteristics compared to the predicate devices do not raise new or different questions of safety or effectiveness. Therefore, clinical testing was not deemed necessary for IntraSight Plus to demonstrate its safety and effectiveness.

Conclusion:

IntraSight Plus has the same intended uses, indications for use, and is intended for the same users within the same intended environments of use as the predicate devices. It meets design verification and validation requirements, including non-clinical testing for software, cybersecurity, interoperability, electromagnetic compatibility, electrical safety, mechanical safety, thermal safety, usability, and packaging.

Differences in technological characteristics primarily reflect the reduction in hardware IntraSight Plus represents due to its merging of predicate device hardware and rendering some of it redundant. The differences do not introduce new intended uses or new indications for use and do not raise new or different questions of safety or effectiveness. IntraSight Plus addresses the differences through non-clinical testing and compliance with appropriate standards, the results of which demonstrate its safety and effectiveness.

Therefore, IntraSight Plus is substantially equivalent to the predicate device IntraSight System (K190078) and predicate device SyncVision System (K190626) with regard to intended uses, indications for use, and technological characteristics.
