Device Story

iLab™ Ultrasound Imaging System provides real-time intravascular anatomy visualization. System inputs: RF ultrasound echo signals from BSC intravascular ultrasound catheters (9-40 MHz). Processing: Data Acquisition PC digitizes RF signals, performs digital signal processing, and stores frames in vector format; Image Processing PC converts vector data to raster-based frames for display. Output: 2D intravascular images on primary/secondary displays. Used in clinical settings (cart-based or installed) by medical professionals to evaluate vessel morphology, detect abnormalities/obstructions, and guide interventional procedures. Benefits: enables visualization of vessel pathology to assist clinical decision-making during transluminal interventions.

Clinical Evidence

Bench testing only. No clinical data presented. Testing included hardware unit-level, software unit-level, and system-level verification. Electrical safety verified per EN 60601-1 and EN 60601-1-2. Acoustic output safety established via equivalence to the predicate Galaxy® System, which uses the same MotorDrive Unit and transducers.

Technological Characteristics

Modular architecture with two PC units (Data Acquisition and Image Processing). Transducer range: 9-40 MHz. Connectivity: Private LAN between PC subsystems. Electrical safety: EN 60601-1, EN 60601-1-2. Configurations: Cart-based or installed. Software: Digital signal processing of RF ultrasound echo; vector-to-raster frame conversion.

Indications for Use

Indicated for patients who are candidates for transluminal interventional procedures, such as angioplasty and atherectomy, requiring intravascular ultrasound examination of pathology.

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.

## Description of the Device

The iLab™ Ultrasound Imaging System is a combination of proprietary hardware and software that has been designed for real-time viewing of intravascular anatomies and is intended to be a basic diagnostic tool for imaging and evaluation of patients who are candidates for transluminal procedures. The iLab™ System is based on a modular and flexible architecture allowing for both mobile and stationary (installed) configurations.

The system is designed for imaging intravascular anatomies with transducer ranges of 9 to 40 MHz. The iLab™ System is also designed to be compatible with multiple Ultrasound Imaging Catheters manufactured by BSC used in different anatomies throughout the body. The system

Confidential

{1}------------------------------------------------

is also supported by a MotorDrive Unit that is compatible with all existing BSC Intravascular Ultrasound (IVUS) catheter products.

The iLab™ System consists of two compact PC units (one for Image Processing and one for Data Acquisition), up to two displays, control devices, media storage devices, and a printer. The Data Acquisition PC (front-end PC) digitizes the RF Ultrasound echo, performs digital signal processing, and stores IVUS frames in a vector-based format. Once saved, the vectorbased frame of data is packetized and sent over a private Local Area Network (LAN) connection onto the Image Processing PC (back-end PC) subsystem. The real-time vector data is unpacked and the frame data is converted from vector-based to raster-based frame, which can then be displayed on the primary and secondary (optional) displays.

The iLab™ System is available in two configurations: a Cart-based Configuration and an Installed Configuration. There is no functional or electrical difference between the Cart-Based and Installed Configurations; differences are limited to cable lengths and the location of the modules of the system.

# Intended Use/Indications

The iLab™ Ultrasound Imaging System is intended for ultrasound examinations of intravascular pathology. Intravascular ultrasound is indicated in patients who are candidates for transluminal interventional procedures such as angioplasty and atherectomy.

# Device Technology Characteristics and Comparison to Predicate Device

The iLab™ System applies ultrasound energy through a transducer enclosed within a catheter. This ultrasound energy is directed from the catheter in the lumen of a vessel into the interior vessel wall of the patient in order to obtain a two-dimensional image of the vessel anatomy. The two-dimensional image, reconstructed from the reflected RF Ultrasound echo, can be used to evaluate the morphology of the vessel and as such potentially detect abnormalities or obstructions. Each of the technological characteristics found in the iLab™ System are identical or similar to those of the predicate device, Galaxy® Intravascular Imaging System. The iLab™ System is similar in design, function, and application to these ultrasound systems.

## Non-clinical Test Results

Bench electrical safety and acoustic output safety testing demonstrate that the iLab™ System and its accessories meet or exceed performance requirements and is safe and effective for its intended use.

{2}------------------------------------------------

### Bench Testing

Bench testing was performed to evaluate the performance and functionality of the iLab™ System. This testing included hardware unit-level tests, software unit-level test, and systemlevel tests. The results demonstrate that the device satisfies all performance and functional requirements.

### Electrical Safety Testing

The iLab™ System complies with EN 60601-1 and EN 60601-1-2 standards as verified by independent test facilities. The iLab™ System software was verified and validated in accordance with applicable FDA quidance documents.

#### Acoustic Output Testing

Acoustic output testing for the iLab™ System is supported by acoustic output data generated with the Galaxy® System for the acoustic output requirements of the iLab™ System, pre and post submission, as required by FDA Guidance, "Information for Manufactures Seeking Market Clearance of Diagnostic Utrasound Systems and Transducers", issued September 30, 1997. The component generating acoustic output on the Galaxy® and iLab™ Systems is the MotorDrive Unit. The MotorDrive Unit was tested with the Galaxy® System (predicate device) and was previously cleared by premarket notification K980851. The iLab™ System utilizes the same MotorDrive Unit.

Design reviews, unit testing, and design verification have been carried out to ensure the transmission signals of the iLab™ System are identical to those generated by the Galaxy® System. Since both the Galaxy® and iLab™ Systems are designed to use the same transducers (catheters), the signal frequency and acoustic efficiency of these transducers (catheters) will be exactly same for each system. Therefore, the final acoustic output level for the Galaxy® and the iLab™ Systems will be the same and acoustic output testing is unwarranted.

#### Conclusion

The iLab™ Ultrasound Imaging System utilizes the same fundamental technology and has the same intended use as the predicate device, the Galaxy® Intravascular Ultrasound Imaging System. The tests support a determination of substantial equivalence of the modified device. the iLab™ Ultrasound Imaging System to the predicate device.
