No
The description mentions a microprocessor and firmware for monitoring functions, but there is no indication of AI or ML being used for decision-making, pattern recognition, or learning.
Yes
The device is intended to remove/aspirate fluid and break-up soft emboli and thrombus from the coronary and peripheral vasculature, which directly treats a medical condition.
No
The device is intended to remove/aspirate fluid and break up soft emboli and thrombus. It is a therapeutic device, not a diagnostic one, as it performs an action to treat a condition rather than identify or monitor it.
No
The device description clearly outlines multiple hardware components including a catheter, pump set, and saline drive unit (SDU), in addition to off-the-shelf accessories. While the SDU contains a microprocessor and firmware, the system is fundamentally a hardware-based medical device with integrated software for control and monitoring.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "remove/aspirate fluid and break-up soft emboli and thrombus from the coronary and peripheral vasculature." This describes a therapeutic procedure performed directly on the patient's body, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a system for physically disrupting and removing material from blood vessels. It involves a catheter, pump, and saline delivery, all designed for a mechanical intervention.
- Lack of Diagnostic Function: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information about a patient's condition.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

Device Description
The ClearLumen II Thrombectomy System is a multi-lumen device that allows for simultaneous hydro-mechanical thrombus disruption and thrombus aspiration. It is designed to simultaneously deliver a stream of high pressure saline via a displacement pump to the distal tip of the catheter, while aspirating thrombotic material macerated by the saline stream.
The system is comprised of three components: The ClearLumen II Catheter, the ClearLumen II Pump Set, and the ClearLumen Saline Drive Unit (SDU). Additional off-the-shelf accessory components are required for device operation and include a vacuum syringe, one way stopcock, aspiration extension tubing and a vacuum sensor.
The 6 Fr, 135 cm, multi-lumen thrombectomy catheter delivers pressurized saline, within the distal catheter inner diameter, to assist in the break-up and removal of soft emboli and thrombus. The distal catheter's 0.014" wire compatible rapid exchange lumen extends and ends in a soft atraumatic tip. The proximal in-line Luer port connects to the pump set, while the Y-connector connects to the vacuum sensor, extension tube, stopcock, vacuum syringe assembly (supplied separately).
The proximal end of the pump set consists of a spike and an in-line drip chamber that is used to pierce the saline bag and connect the pump set to the saline source. The cassette, which is centered in the pump set, contains a piston pump and is mounted onto the SDU. The cassette is powered by the motor contained in the SDU. The distal end of the pump set has a connector, which mounts to the proximal end of the Y-connector of the catheter and delivers the saline to the catheter.
The SDU is a reusable, IV pole mounted device. The fork drive of the SDU is designed to run the piston pump contained in the pump set to deliver the stream of saline to the catheter, when activated by the vacuum sensor. Vacuum is achieved by a vacuum syringe (not provided), which is connected to the vacuum sensor. The vacuum sensor is connected to the aspiration lumen on the Y-connector of the catheter. The SDU contains a microprocessor controlled circuit and firmware that monitors various functions of the motor and vacuum to assure that the device is functioning as expected. Various colored LED lights on the front panel indicate to the user what the current status is of the SDU. Energy is provided by a 24 volt external power supply, which is connected to mains power.
