Device Story

Revolution™ 45 MHz Rotational IVUS Imaging Catheter is a diagnostic intravascular catheter used for coronary artery imaging. Device consists of imaging core with 45MHz ultrasonic transducer and catheter body with telescoping section for 150mm linear pullback. Operated by physician in clinical setting; requires heparinized saline flush for acoustic coupling. Connects to patient-user interface (PIM) instrument via electromechanical connector. Provides real-time ultrasound visualization of coronary anatomy to assist clinicians during transluminal interventional procedures. Benefits include improved visualization of vessel morphology to guide clinical decision-making.

Clinical Evidence

Bench testing only. Biocompatibility testing performed in accordance with ISO 10993-1; results met predetermined acceptance criteria. No clinical data presented.

Technological Characteristics

Rotational ultrasound catheter; 45 MHz transducer; 3.2F crossing profile; 135cm length; 150mm pullback capability. Materials include radiopaque marker. Connectivity via electromechanical interface to PIM. Sterile, single-use. Biocompatibility per ISO 10993-1.

Indications for Use

Indicated for patients who are candidates for transluminal interventional procedures requiring intravascular ultrasound examination of coronary arteries.

Regulatory Classification

Identification

An intravascular diagnostic catheter is a device used to record intracardiac pressures, to sample blood, and to introduce substances into the heart and vessels. Included in this generic device are right-heart catheters, left-heart catheters, and angiographic catheters, among others.

The Revolution™ 45 MHz Rotational IVUS Imaging Catheter consists of two main assemblies; the imaging core and the catheter body. The catheter body comprises three sections; the distal section with a 0.014" compatible F/X port, single lumen proximal section, and a telescope section. The distal section and proximal single lumen sections comprise the useable length of the catheter, the telescoping section remains outside of the guiding catheter. The telescope shaft allows the imaging core to be advanced and retracted for up to 150mm of linear movement. The corresponding movement of the transducer occurs from the proximal end of the guide wire exit port to the proximal end of the window portion of the distal section.

The imaging core is composed of a hi-torque, flexible, rotating drive cable with an outward looking 45MHz ultrasonic transducer at the distal tip. An electromechanical connector interface at the proximal end makes the connection to the patient-user interface (PIM) instrument. The PIM-catheter interface consists of an integrated mechanical drive assembly and electrical connection.

A flush port with a one-way valve is used to displace the air. The catheter must be flushed with heparinized saline prior to use, as this provides the acoustic coupling media required for ultrasonic imaging. The one-way valve helps retain saline in the catheter during use.

The catheter body has a distal guidewire lumen with proximal exit port at 2cm from the distal end. A coupling is used to attach the catheter body to the telescope shaft. A radiopaque (RO) marker is embedded in the catheter body at 0.5cm from the tip. In addition, two insertion depth indicators are located on the catheter body at 90cm corresponding to brachial insertions, and at 100cm corresponding to femoral insertions.

## Intended Use:

The Revolution™ 45 MHz Rotational IVUS Imaging Catheter is intended for the intravascular ultrasound examination of coronary arteries. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal interventional procedures.

#### Device Technological Characteristics and Comparison to Predicate Device:

The Revolution™ 45 MHz Rotational IVUS Imaging Catheter is substantially equivalent to: Hewlett Packard 3.2/45 MHZ CORONARY IMAGING CATHETER (Intravascular Ultrasound Imaging Catheter) cleared under K974457 on July 14. 1998. The Scout rotational catheter device developed by Hewlett Packard and cleared under 510(k) K974457 is modified in several physical design aspects (the mechanism for retracting and advancing the imaging core was upgraded) as well as a few material changes or additions. The fundamental scientific technology remains the same; rotational ultrasound catheter.

The Revolution™ 45 MHz Rotational Imaging Catheter uses the same fundamental scientific technologies and has the same intended use as that of the predicate device, Scout 3.2/45 MHz Coronary Imaging Catheter.

## Performance Data:

Applicable testing was performed in accordance with Design Controls including a risk analysis addressing the impact of modifications to the device and components. The device was tested for biocompatibility according to ISO 10993-1 and the results met the predetermined acceptance criteria.

#### Conclusion:

Revolution™ 45 MHz Rotational Imaging Catheter has the same Intended Use and utilizes the same fundamental scientific technology as that of the predicate device, Scout 3.2/45 MHz Coronary Imaging Catheter cleared under K974457 on July 14, 1998. Modifications to the device do not raise any new questions regarding safety and efficacy. The performance data and a declaration of conformity with design controls support a determination of substantial equivalence of the modified device to the predicate device.
