QuadraSphere Microspheres are indicated for embolization of hypervascularized tumors including hepatoma, and peripheral arteriovenous malformations.
Not Found
The provided document is a 510(k) premarket notification letter from the FDA to Biosphere Medical, S.A. regarding their Quadrasphere Microspheres. This document largely focuses on regulatory approval and indications for use, and therefore does not contain information about acceptance criteria or a study proving the device meets said criteria.
The typical content of such a study would include:
- Acceptance Criteria Table and Device Performance: A table outlining specific performance metrics (e.g., size distribution, mechanical strength, biocompatibility, embolization efficiency, clinical success rates, complication rates) with pre-defined acceptance limits and the observed performance of the Quadrasphere Microspheres.
- Sample Size and Data Provenance: Details about the number of patients or samples included in the test set, as well as the geographical origin of the data (e.g., USA, France, multi-national) and whether the data was collected retrospectively (from existing records) or prospectively (specifically for the study).
- Ground Truth Experts: Information on the number of medical experts (e.g., interventional radiologists, pathologists) who established the ground truth for the test set, along with their qualifications (e.g., years of experience, board certifications).
- Adjudication Method: If applicable, how discrepancies among experts were resolved to establish the ground truth (e.g., 2+1 means two experts agree, and a third is consulted if they disagree; 3+1 implies a similar consensus-based approach).
- MRMC Comparative Effectiveness Study: If a multi-reader, multi-case study was conducted, the document would describe its design and report the effect size quantifying how much human readers' performance (e.g., accuracy, diagnostic confidence) improved when using Quadrasphere Microspheres compared to a control or alternative treatment.
- Standalone Performance Study: Whether a study evaluating the device's performance in isolation (without human intervention, if applicable to the device type) was performed. For an embolic agent, this might relate to its physical properties and in-vitro performance.
- Ground Truth Type: The specific method used to establish the "true" clinical outcome or characteristic against which the device's performance was measured (e.g., confirmation by pathology after embolization, long-term patient outcomes, expert consensus on imaging results).
- Training Set Sample Size: If a machine learning component were involved (which is not the case for this physical medical device), the size of the dataset used to train the algorithm would be specified.
- Training Set Ground Truth: How the ground truth for any training set was established.
Without a detailed study report, which is not part of this 510(k) letter, I cannot provide the requested information.

Dear Alix Fonlladosa,
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
{1}------------------------------------------------
related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Industry and Consumer Education at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address

§ 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).
