The 510(k) summary describes a mechanical device (implant and delivery system) and its performance testing, with no mention of AI or ML capabilities.
Yes
The device is indicated for arterial and venous embolizations, which is a therapeutic intervention to block blood vessels.
No
The device description and intended use indicate that this system is used for arterial and venous embolizations, which is a therapeutic (treatment) procedure, not a diagnostic one.
No
The device description clearly describes a physical implant made of Nitinol wire mesh and a delivery device, indicating it is a hardware medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
- Device Description: The Nfocus Neuromedical Acta Vessel Occlusion System (VOS) is an implantable device designed to be delivered into the body to embolize (block) blood vessels. It is a physical device used for a therapeutic purpose, not a test performed on a sample.
- Intended Use: The intended use is for "arterial and venous embolizations in the peripheral vasculature," which is a procedure performed within the body.
The information provided clearly describes a device used for an interventional procedure within the body, not a diagnostic test performed on a sample outside the body.

Device Description
The Acta "Vessel Occlusion System (VOS) is provided sterile and is intended for one-time use. The implant is a self-expandable, ovoid shaped implant with delivery device. The implant is made from a double layer of Nitinol wire mesh which is secured at proximal and distal ends with platinum marker bands. The delivery device allows the implant to be delivered through commercially available catheters. Detachment of the implant from the delivery device is achieved by operator activation of the delivery handle.

§ 870.3300 Vascular embolization device.
(a)
Identification. A vascular embolization device is an intravascular implant intended to control hemorrhaging due to aneurysms, certain types of tumors (e.g., nephroma, hepatoma, uterine fibroids), and arteriovenous malformations. This does not include cyanoacrylates and other embolic agents, which act by polymerization or precipitation. Embolization devices used in neurovascular applications are also not included in this classification, see § 882.5950 of this chapter.(b)
Classification. Class II (special controls.) The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices.” For availability of this guidance document, see § 870.1(e).

Dear Mr. O'Holla:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
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. In addition, FDA may publish further announcements concerning your device in the Federal Register.
