Indications for Use
The Volcano s5i™ Series Intravascular Imaging and Pressure 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. VH® IVUS is intended to be used in conjunction with imaging catheters during diagnostic ultrasound imaging of the peripheral and coronary vasculature. The Volcano VH IVUS System is intended to semiautomatically visualize boundary features and perform spectral analysis of RF ultrasound signals of vascular features that the user may wish to examine more closely during routine diagnostic ultrasound imaging examinations. 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 PIM1 withdraws the imaging core within the protective sheath for a maximum of 15 cm.
Device Story
System integrates intravascular ultrasound (IVUS) imaging and pressure measurement. Inputs include RF ultrasound signals from imaging catheters and pressure data from guidewires/ECG equipment. System processes signals to display high-resolution intraluminal images, blood flow information (ChromaFlo), and spectral analysis of vascular features (VH IVUS). Used in cath labs by physicians/technicians to evaluate vascular morphology and hemodynamics. Output displayed on console for real-time clinical decision-making during diagnostic or interventional procedures. Modification involves updated CPU motherboard for enhanced efficiency; maintains fundamental technology and functionality of predicate.
Clinical Evidence
Bench testing only. Performance data included signal processing verification, reliability HALT, electrical safety, electromagnetic compatibility, and software testing. No clinical data required for this CPU motherboard modification.
Technological Characteristics
Ultrasonic pulsed echo imaging system; integrated IVUS and pressure monitoring. Features include ChromaFlo (flow imaging), VH IVUS (spectral analysis), and rotational 45MHz imaging. Connectivity via Patient Interface Modules (PIMs). Modification: CPU motherboard upgrade. System is non-patient contacting.
Indications for Use
Indicated for qualitative and quantitative evaluation of vascular morphology in coronary and peripheral arteries; adjunct to angiography for vessel lumen/wall imaging; qualitative blood flow assessment (ChromaFlo); semiautomatic visualization of boundary features and spectral analysis of RF ultrasound signals (VH IVUS); and intravascular blood pressure measurement in coronary and peripheral vessels.
Regulatory Classification
Identification
An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. 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.
