Intended Use

Embozene® Microspheres are indicated for the embolization of arteriovenous malformations and hypervascular tumors including uterine fibroids and hepatoma.

ONCOZENE™ Microspheres are indicated for the embolization of arteriovenous malformations and hypervascular tumors including hepatoma.

Device Description

Embozene® Microspheres and ONCOZENE™ Microspheres are tightly calibrated, compressible microspheres intended to occlude vasculature for the purpose of blocking blood flow to a target tissue such as a hypervascular tumor (HVT) or arteriovenous malformation (AVM). The microspheres are manufactured from sodium polymethacrylate and coated with proprietary Polyzene®F. The microspheres are compressible to enable smooth delivery through the indicated delivery catheter. Embozene® Microspheres are available opaque or color coded by size to allow easy identification of the different sizes; ONCOZENE™ Microspheres are available in opaque only.

Embozene® / ONCOZENE™ Microspheres are supplied sterile and packaged in 20ml polycycloolefin syringes with a standard 7ml fill volume across the range. Embozene® Microspheres syringes or vials are available in 1 ml or 2 ml microsphere volume; ONCOZENE™ Microspheres are available in 2 ml or 3 ml microsphere volume.

AI/ML Overview

The provided document is a 510(k) Summary of Safety and Effectiveness for CeloNova BioSciences' Embozene® Microspheres and ONCOZENE™ Microspheres. This document focuses on demonstrating substantial equivalence to existing predicate devices, rather than establishing acceptance criteria and proving new device performance against those criteria as would be typical for a novel device.

The core of this submission is an expanded indication for use to explicitly include "hepatoma" among the hypervascular tumors treated with these embolization devices. Therefore, the "acceptance criteria" here are implicitly related to the safety and effectiveness for this expanded indication, demonstrated by comparison to predicate devices and existing clinical data.

Here's an analysis based on your requested information:

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a 510(k) for an expanded indication and not a de novo submission, there are no explicit, quantifiable "acceptance criteria" presented in the document in the format of a novel device performance study. Instead, the "acceptance criteria" are implied to be demonstration of substantial equivalence to legally marketed predicate devices, particularly regarding the safety and effectiveness for the embolization of hypervascular tumors, specifically hepatoma.

The "device performance" is primarily the finding that the subject devices are substantially equivalent to the predicate devices and that existing clinical data supports their safety and effectiveness for the expanded indication.

Acceptance Criteria (Implied for Substantial Equivalence)Reported Device Performance
Maintain identical technological characteristics to predicate devices.The subject devices (Embozene® and ONCOZENE™ Microspheres) have identical technological characteristics, manufacturing, processing, and sterilization as their predicate counterparts (K073417/K132675/K133447 and K130307).
Existing clinical data demonstrates safety and effectiveness for embolization of hypervascular tumors, including hepatoma.A review of published and unpublished data on the use of Embozene® for hypervascular tumors (including hepatoma outside the US) and postmarket experience with cleared devices did not identify any unique safety concerns regarding hepatoma embolization. The data were deemed "sufficient to support the safety and effectiveness" for this indication.
No new performance standards applicable.There are no new performance standards applicable to the device beyond existing guidance.

2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Sample Size: Not explicitly stated as a defined "test set" with a specific sample size. The clinical information reviewed included "published and unpublished data on the use of Embozene® for the treatment of hypervascular tumor including hepatoma (outside the United States) and postmarket experience with the cleared device." The exact number of patients or cases in this cumulative "test set" is not provided.
  • Data Provenance: The data provenance mentioned is "outside the United States" for the use of Embozene® for hepatoma, and general "postmarket experience" with the cleared devices. This suggests a mix of retrospective (published studies, postmarket reports) and potentially some prospective data if "unpublished data" includes ongoing registries or smaller studies.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

The document does not specify the number or qualifications of experts used to establish a "ground truth" for a specific test set. The clinical information reviewed was "published and unpublished data" and "postmarket experience," implying that the assessment of safety and effectiveness relied on existing medical literature and real-world usage data, which inherently includes diagnoses and outcomes established by medical professionals in various clinical settings.

4. Adjudication Method for the Test Set

No explicit adjudication method is mentioned. The review seems to be a synthesis of existing literature and postmarket surveillance rather than a specific study with a defined adjudication process.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. This submission is for an expanded indication based on substantial equivalence and a review of existing data, not for a comparative effectiveness study of human readers with or without AI assistance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This question is not applicable. The device is a medical product (microspheres for embolization), not an algorithm or AI.

7. The Type of Ground Truth Used

The "ground truth" for demonstrating safety and effectiveness for hepatoma embolization was based on the outcomes data and findings reported in published and unpublished clinical studies, as well as postmarket surveillance data. This includes diagnoses by clinicians, treatment effectiveness, and adverse events.

8. The Sample Size for the Training Set

This question is not applicable. The device is a medical product, not an AI or algorithm that requires a "training set." The submission relies on existing clinical evidence, not a machine learning model.

9. How the Ground Truth for the Training Set Was Established

This question is not applicable for the reasons mentioned above.

7. Summary of Non-Clinical Performance Testing

There are no performance standards applicable to the device is subject Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices issued on December, 29 2004. Non-clinical performance testing conducted on the predicate device includes:

  • Chemical analysis
  • Size range
  • Catheter compatibility ●
  • Density ●
  • . Packaging performance
  • Shelf Life
  • Sterility ●
  • Biocompatibility ●

No new testing was conducted since the predicate device and the subject device have identical technological characteristics, manufacturing, processing, and sterilization.

{9}------------------------------------------------

8. Summary of Clinical Experience

The clinical information submitted included a review of embolization using various embolic agents to physically occlude vessels to restrict blood flow over the last ten years, published and unpublished data on the use of Embozene® for the treatment of hypervascular tumor including hepatoma (outside the United States) and postmarket experience with the cleared device.

Review of published and unpublished data regarding adverse events associated with Embozene® Microspheres and ONCOZENE™ Microspheres did not identify any unique safety concerns regarding use of Embozene® Microspheres and ONCOZENE™ Microspheres for hepatoma embolization.

9. Conclusion

The Embozene® Microspheres and ONCOZENE™ Microspheres that are the subject of this 510(k) submission are substantially equivalent to the two predicate devices (Embozene® Microspheres K073417/K132675/K133447 and ONCOZENE™ Microspheres K130307) when indicated for the more general intended use of embolization of hypervascular tumors. The data on hepatoma embolization are sufficient to support the safety and effectiveness of Embozene Microspheres and ONCOZENE™ Microspheres for embolization of hepatoma.

§ 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).
