The Patch reinforces the soft tissue of the lung thereby sealing or reducing air leaks that occur during pulmonary surgery.
• Reinforce soft tissue of the lung
• Seal or reduce air leaks in thoracic surgery
The Patch is a bioresorbable film containing gelatin. Each Patch is supplied sterile and non-pyrogenic in a single-use package.

Here's an analysis of the provided text regarding the acceptance criteria and study for the Fusion Medical Technologies, Inc. "The Patch" device:
The provided text does not explicitly define specific, quantitative acceptance criteria for the device's technical performance. Instead, it offers a general statement about the successful closure of air leaks.
Here's the breakdown based on your requested information, extracting what's available and noting what's not:
Acceptance Criteria and Device Performance
| Acceptance Criteria (Explicitly Stated) | Reported Device Performance |
|---|---|
| Not explicitly defined as a quantitative metric for "success". The closest is "successful closure." | 96% of 52 treated air leaks were deemed to have "successful closure." |
| Biocompatibility requirements (Implicit from testing) | Passed all specified biocompatibility tests. |
| No product related adverse effects | No product related adverse effects were noted during the study. |
Study Details
2. Sample size used for the test set and the data provenance
- Test Set Sample Size: 26 patients. A total of 52 air leaks were treated.
- Data Provenance: Multi-center, open-label study. The country of origin is not specified but is implicitly within the regulatory scope of the FDA given the 510(k) submission. It is a prospective clinical study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
The document does not specify the number of experts or their qualifications used to establish the "successful closure" ground truth for the air leaks. It's implied that the clinical investigators participating in the multi-center study made these determinations.
4. Adjudication method for the test set
The document does not specify any explicit adjudication method (e.g., 2+1, 3+1). The assessment of "successful closure" was likely made by the treating physicians/investigators at each study center.
5. If a multi-reader, multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs. without AI assistance
No, an MRMC comparative effectiveness study was not done. This device is a surgical patch, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is a medical device (surgical patch), not an algorithm.
7. The type of ground truth used
The ground truth for the "successful closure" of air leaks was based on clinical assessment by the investigators/treating physicians during the pulmonary surgery and follow-up.
8. The sample size for the training set
The document does not mention a training set. This is a physical medical device, and the concept of a "training set" as understood in AI/ML contexts does not apply here. The "clinical tests" described are considered the pivotal study for performance evaluation.
9. How the ground truth for the training set was established
Not applicable. As above, no training set in the AI/ML sense was used or described.

7. Performance Data
Nonclinical Tests 7.1
Standard biocompatibility testing was performed according to the FDAmodified matrix recommended in FDA memorandum #G95-1 entitled, "Use of International Standard ISO-10993, Biological Evaluation of Medical Device Part-1: Evaluation and Testing".
The product passed all of the following biocompatibility tests:
Hemocompatibility Cytotoxicity -- ISO agarose overlay Cytotoxicity--ISO elution method Acute Systemic Toxicity Irritation -- Intracutaneous Reactivity Genotoxicity -- Ames mutagenesis Genotoxicity -- Sister chromatid exchange Genotoxicity--Chromosomal aberration Sensitization -- Magnusson and Kligman Implantation/Subchronic Toxicity
7.2 Clinical Tests
Twenty six patients were enrolled in a multi-center, open label study in which the Patch was used to seal air leaks that occur during pulmonary surgery. Of the 52 leaks that were treated with the Patch, 96% were deemed to have successful closure. No product related adverse effects were noted during the study.
7.3 Conclusions Drawn from Nonclinical and Clinical Testing
The conclusions drawn from the nonclinical and clinical testing were that the product is biocompatible and functional for the intended use.
§ 878.3300 Surgical mesh.
(a)
Identification. Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Examples of surgical mesh are metallic and polymeric mesh for hernia repair, and acetabular and cement restrictor mesh used during orthopedic surgery.(b)
