The Ivy Sports Medicine Collagen Meniscus Implant (CMI) is intended for use in surgical procedures for the reinforcement and repair of soft tissue injuries of the medial meniscus. In repairing medial meniscal defects, the patient must have an intact meniscal rim and anterior and posterior horns for attachment of the mesh. In addition, the surgically prepared site for the CMI must extend at least into the red/white zone of the meniscus to provide sufficient vascularization.
The CMI reinforces soft tissue and provides a resorbable scaffold that is replaced by the patient's own soft tissue. The CMI is not a prosthetic device and is not intended to replace normal body structure.
The Ivy Sports Medicine Collagen Meniscus Implant XL (CMI XL) is a resorbable collagen matrix comprised primarily of bovine type I collagen. The CMI is provided in a semi-lunar shape with a triangular cross section to be used to reinforce weakened soft tissue and provide a resorbable scaffold that is replaced by the patient's own tissue. The surgeon trims the device to the size necessary for repair of the damaged or weakened soft tissue. The CMI XL is provided sterile for single use only.
The provided text describes a 510(k) premarket notification for a medical device called the Ivy Sports Medicine Collagen Meniscus Implant XL (CMI XL). It asserts substantial equivalence to a predicate device, the ReGen Collagen Scaffold (K082079).
Based on the provided document, here's a breakdown of the requested information:
1. Table of acceptance criteria and the reported device performance
The document states: "Testing performed on the Collagen Meniscus Implant XL demonstrated that all of the predetermined acceptance criteria were met with passing results." However, it does not explicitly list the specific acceptance criteria or the numerical performance results against those criteria. It only makes a general statement about meeting them.
2. Sample size used for the test set and the data provenance
The document does not provide details on the sample size used for the test set or the data provenance. It mentions "Design verification testing" and "Bench performance test data" but no specifics on how many devices were tested or where the components/data originated.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not applicable as the document indicates "Clinical evaluation is not required for this device." The testing performed appears to be bench testing rather than clinical studies requiring expert ground truth for interpretation.
4. Adjudication method for the test set
This information is not applicable as the document indicates "Clinical evaluation is not required for this device" and the testing described is bench performance testing.
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
This information is not applicable. The device is a physical collagen implant, not an AI-assisted diagnostic or interpretative tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable. The device is a physical collagen implant, and there is no algorithm or human-in-the-loop component described.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Since clinical evaluation was not required and the testing was described as "Design verification testing" and "Bench performance test data," the ground truth would likely be established by engineering specifications, material science standards, and comparison to the predicate device's established performance. The document implicitly suggests that the ground truth for performance relied on the predicate device's characteristics.
8. The sample size for the training set
This information is not applicable. The device is a physical implant, not an AI model that requires a training set.
9. How the ground truth for the training set was established
This information is not applicable. The device is a physical implant, not an AI model that requires a training set.
In summary, the document focuses on demonstrating substantial equivalence through bench testing, asserting that the new device meets predefined, unlisted, acceptance criteria based on the predicate device's performance, and explicitly stating that clinical evaluation was not required.
§ 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)
