• Submission Type: Special
• Regulation: 21 CFR 870.3300
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Embozene® Microspheres are indicated for the embolization of hypervascular tumors and arteriovenous malformations.

Device Story

Embozene® Microspheres are calibrated, compressible, spherical embolic agents; manufactured from sodium polymethacrylate coated with Polyzene®-F. Used to occlude vasculature; block blood flow to target tissues like hypervascular tumors (HVT) or arteriovenous malformations (AVM). Supplied sterile in polycycloolefin syringes or vials; color-coded by size (40 μm to 1300 μm) for identification. Delivered via catheter by physicians in clinical settings. Compression allows smooth delivery through catheters. Occlusion of target vessels reduces blood flow to lesions, providing therapeutic benefit for hypervascularized conditions.

Clinical Evidence

No new clinical trials conducted. Evidence based on literature review of Transarterial Embolization (TAE) using various embolic agents over ten years, unpublished data, and post-market surveillance. Concluded that Embozene® Microspheres, including the new 1100 μm and 1300 μm sizes, are safe and effective for the indicated use.

Technological Characteristics

Materials: Sodium polymethacrylate core, Polyzene®-F coating. Form factor: Compressible microspheres, 40-1300 μm diameter. Delivery: Syringe or vial, sterile, pyrogen-free. Connectivity: None. Energy source: None (mechanical).

Indications for Use

Indicated for embolization of hypervascular tumors and arteriovenous malformations in patients requiring vascular occlusion.

Regulatory Classification

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.

Special Controls

*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).

#### 5. Similarities and Differences to Predicate device

The intended use of the subject device remains unchanged as compared to the predicate. The subject device and the predicate have the same design, specifications, fundamental scientific technology, and packaging. The only change is the addition of 1100 um and 1300 µm sizes of Embozene® Microspheres. The additional sizes are available in gray and pink colors, respectively. The colorants used to create those colors are the same as those used in the predicate.

Comparison between the Subject Device (Embozene®) and the Predicate Device (Embozene®)

#### 7. Summary of In-Vitro Testing

Size distribution and catheter compatibility testing were conducted on the subject device and concluded to be equivalent to the predicate.

8. Summary of Clinical Experience

{3}------------------------------------------------

The clinical evaluation included in the 510(k) reviews Transarterial Embolization (TAE) using various embolic agents to physically occlude vessels to restrict blood flow over the last ten years. The overall review of the scientific literature, unpublished data and post market surveillance, indicate that Embozene® Microspheres including 1100 um are reasonably safe and effective for the treatment of hypervascular tumors and arteriovenous malformations. Therefore, it could be concluded that the benefits of TAE with Embozene microspheres family including the additional 1100 and 1300 um microspheres for the treatment of hypervascular tumors and arteriovenous malformations outweigh the potential risk when used within their labeled application.

#### 9. Summary

The subject device and the predicate have the same indications for use, design, and fundamental scientific technology. The subject device Embozene® Microspheres with the addition of 1100 um and 1300 um sizes are substantially equivalent to the cleared Embozene® Microspheres (K073417).

Dear Ms. Barber:

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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set
