The EKOS Micro-Infusion System is intended for the controlled and selective infusion of physician-specified fluids, including thrombolytics, into the peripheral vasculature.

The EKOS Micro- Infusion System is intended for regional infusion of contrast materials into selected vessels in the neurovasculature. The EKOS Micro- Infusion System may be used for controlled, regional infusion into selected vessels and is not intended for use in the coronary vasculature.

Device Description

The system consists of a disposable infusion/ultrasound catheter and an instrument that generates and controls the delivery of energy to the catheter. The catheter contains a single ultrasound transducer, located at the distal tip, a thermal sensor and a distal end hole for placement over a guide wire and fluid infusion.

AI/ML Overview

This document is a 510(k) notification for a medical device called the EKOS Micro-Infusion System. It is a submission to the FDA requesting clearance to market the device, demonstrating its substantial equivalence to previously cleared devices. It is not a study reporting on the performance of an AI/ML device.

Therefore, the provided document does not contain the information requested in your prompt regarding acceptance criteria, study details, sample sizes, expert ground truth, or MRMC studies for an AI/ML device.

The document describes a medical device (a catheter system), its intended use, technological characteristics, and its comparison to predicate devices, primarily focusing on hardware and safety/equivalence as per regulatory requirements for a 510(k) submission. It does not involve AI or algorithms that would have performance metrics like sensitivity, specificity, or AUC, established by expert consensus or pathology, which are typically found in studies for AI/ML diagnostic or predictive devices.

Trade Name: EKOS Micro-Infusion System Regulation Number: 21 CFR 870.1200 Regulation Name: Diagnostic intravascular catheter Regulatory Class: II Product Code: NUI Dated: May 11, 2005 Received: May 12, 2005

Dear Ms. Kersten:

We have reviewed your Section 510(k) premarket notification of intent to market the device we nave reviewed your becally is (a) the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate for use stated in the energency to stg-enactment date of the Medical Device Amendments, or to conninered pror to trial) 2011-17-17 (1) accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls and Cosment the Act and the limitations described below. The general controls provisions of the provisions of the Arc and for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

The Office of Device Evaluation has determined that there is a reasonable likelihood that this The Office will be used for an intended use not identified in the proposed labeling and that such use device win be used for an meeting accordance with Section 513(i)(1)(E) of the Act, the following Courd cause ham. "Therefore, x warning, immediately following the indications for use, in the device's labeling:

"The safety and effectiveness of the EKOS Micro-Infusion System for thrombolytic therapy in The sately and creceiveness of the Erablished. Further clinical studies are necessary to ensure the neurovasculature nave not been setuis therapy into the neurovasculature does not result in an increased incidence of adverse events (e.g., intracranial hemorrhage)."

Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.

The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your Section 5 l0(k) premarket notification if the limitation statement described above is added to your labeling.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
