Based on the provided information, the Provisio™ SLT IVUS™ System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to evaluate vascular morphology and provide dimensional measurements in blood vessels of the peripheral vasculature. This is a direct assessment of the patient's anatomy in vivo.
- Device Description: The system uses intravascular ultrasound (IVUS) with a catheter inserted into the blood vessels. It generates real-time dimensions and representations of the vessel's flow lumen. This is a direct imaging and measurement technique performed within the body.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens derived from the human body (like blood, tissue, or urine) outside of the body. IVD devices are specifically designed for testing these types of samples in a laboratory setting.
The Provisio™ SLT IVUS™ System is a medical device used for in vivo diagnostic imaging and measurement within the peripheral vasculature.

Device Description
The Provisio™ Sonic Lumen Tomography Intravascular Ultrasound ("SLT IVUS™") System is an IVUS system that utilizes A-mode ultrasound operation to evaluate the vessel lumen and provide dimensional measurements in real time. The Provisio™ SLT IVUS™ System comprises the SLT IVUS™ Support Crossing Catheter and the SLT IVUS™ P1 System, which includes the Pulser Receiver Unit, the Display Unit, and a Cart.
The SLT IVUS™ Support Crossing Catheters, provided sterile for single use, are over-the-wire intravascular ultrasound catheters with a digital ultrasound transducer array at the distal end. The information from the echoes is used to generate real-time dimensions and representations of the peripheral vessel's flow lumen. If required clinically, the SLT IVUS™ Support Crossing Catheter also functions as a support crossing catheter and may be used for the infusion of saline or radiopaque contrast agents.
The Provisio™ SLT IVUS™ System may be used in peripheral vascular procedures to generate real-time measurements of the vessel flow lumen dimensions, while also providing the functionality of the support crossing catheter in the same procedure. The cross-sectional parameters of diameter and area are displayed as numbers; additionally, the diameter measurement is graphically displayed as a representation of the flow lumen. The cross-sectional area measurements are displayed over time on a timeline display. As the catheter is moved by the operator through the vessel lumen, new crosssectional measurements are obtained and displayed. Adjacent cross-sectional measurements can be compiled and displayed over a period of time to create an orthogonal graphical display of the vessel lumen (called RunView™).

The Provisio™ SLT IVUS™ System is intended to be used by physicians trained in peripheral interventional procedures as an adjunct to conventional angiographic procedures.
Intended Use/Indications for Use
21 CFR 807.92(a)(5)
The Provisio™ SLT IVUS™ System is designed for use in the evaluation of vascular morphology in blood vessels of the peripheral vasculature.
The Provisio™ SLT IVUS™ System is designed for use as an adjunct to conventional angiographic procedures to evaluate the vessel lumen and provide dimensional measurements.
The SLT IVUS™ Support Crossing Catheter also guides and supports a guidewire during access of the vasculature and provides a conduit for the delivery of saline solutions or radiopaque contrast agents.
Indications for Use Comparison
21 CFR 807.92(a)(5)
The Provisio™ SLT IVUS™ System combines the features of an IVUS system (IVUS catheter and associated imaging system) and a support crossing catheter into a single product. As an IVUS System intended to support the evaluation of vascular morphology in blood vessels of the peripheral vasculature, the proposed device has the same intended use as the Philips Image Guided Therapy Corporation Reconnaissance PV .018 OTW Digital IVUS Catheter (K200410) primary predicate when used with the Volcano Corporation s5/s5i/CORE/CORE Mobile Precision Guided Therapy System (K173860) secondary predicate. As a support crossing catheter, the proposed device has the same intended use as the Spectranetics Corporation Quick-Cross® Extreme Support Catheters (K092396) secondary predicate. To reflect this combined functionality, the Indications for Use statement of the proposed device accordingly includes elements of the Indications for Use statements of each of the predicate devices, as it relates to their respective functionality.
Technological Comparison
21 CFR 807.92(a)(6)
IVUS procedures, which are an adjunct to angiography procedures, are commonly used in the peripheral vasculature with a combination of devices: (1) IVUS catheter, (2) imaging system, and (3) support catheter often prior to, and following, the conduct of interventional and therapeutic procedures. The proposed device, and the predicate devices in combination, are similarly part of the complete procedural workflow in the peripheral vasculature for which IVUS is used. The proposed device is likewise similar in technology to the predicate devices.
There are differences between the proposed device and the predicate devices, primarily with respect to the proposed device's A-mode ultrasound operation and its associated display of ultrasound data. Specifically:
- . When considered from the perspective of their roles as percutaneous catheters for their respective use within the peripheral vasculature, the proposed device is similar to the Reconnaissance and Quick-Cross predicate devices with respect to catheter form factor and design features, and any minor differences (e.g., crossing profile and other dimensional considerations) do not affect the intended use and clinical function, and as such, do not raise different questions of safety or effectiveness.
- With respect to use of ultrasound energy, the proposed device and the Reconnaissance primary predicate device both utilize acoustic energy that is sent toward and reflected by the vessel wall, and minor differences in ultrasound parameters do not affect the acoustic safety, basic safety, or essential performance requirements of the device as an IVUS System for use in peripheral vessels, and thus do not raise different questions of safety or effectiveness.
- With respect to their analysis approaches for vessel measurement, both the proposed device and the Volcano IVUS secondary predicate device analyze ultrasound signal reflections
6
(echoes) from the vessel wall to yield vascular morphology information. Both devices provide a visual representation of the vessel lumen and a similar range of numerical measurements. Furthermore, in both devices, the information is intended for interpretation by a trained physician in conjunction with, and/or as an adjunct to, angiographic findings. Thus, while analysis methodology (A-mode) and display (spline and measurements vs. vessel image) are different between the proposed and predicate devices, they do not affect the type of information or their clinical use, and thus do not raise different questions of safety or effectiveness.
Therefore, Provisio Medical is of the opinion that these technological differences do not raise different questions of safety or effectiveness especially when viewed in relation to the workflow and key functionalities of the predicate devices.
