GEM™ BIOVER disposable microvascular clamps are instruments which are used for all microsurgical procedures. They are used to occlude vessels during anastomosis, which is necessary as a result of vessel damage or thrombosis.
The GEM™ Biover Microvascular Clamps (Clamps) are arterial and venous clamps in both single and double clamp configurations, available in varying sizes. The clamps are sterile, disposable clamps for single use. The clamps are used in microsurgery, plastic surgery, and hand surgery for the temporary occlusion of blood vessels during an anastomosis.
The clamps are available for arteries and veins. The clamping force is higher for the arterial clamps than for the veinous clamps. The clamps are identified by a product reference code and by the color of the clamp. The clamps for veins are green, and the clamps for arteries are yellow.
The clamps are packaged individually in two Tyvek pouches (double pouched). The devices in the Tyvek pouches are gamma sterilized and are placed in cartons of 10. The clamps are used once and are disposed of after use.
This document is a 510(k) summary for the GEM™ Biover Microvascular Clamps, asserting their substantial equivalence to a previously cleared predicate device. This type of submission generally focuses on demonstrating that a new device is as safe and effective as a legally marketed predicate device, rather than proving performance against specific quantitative acceptance criteria in a robust statistical study.
Based on the provided text, the device is not an AI/ML powered device, nor is it a diagnostic device that requires high-level performance metrics, such as sensitivity, specificity, or AUC. The submission is for a physical medical device (microvascular clamps). Therefore, the information requested in the prompt regarding AI/ML performance metrics, sample sizes for test/training sets, expert adjudication, MRMC studies, and ground truth establishment is not applicable to this document.
The document states:
- "The GEM Biover microvascular clamps remain unchanged from the predicate device."
- "There are no engineering or performance changes to the device or its packaging."
The "performance data" section mentions:
- "The label design change and the outer carton sales unit design change were assessed and validated in a Packaging Summative Human Factors/Usability Study."
- "Historical complaint data were reviewed and indicate no use-related concerns, thus, there are no use-related risks or complaints that trigger a need for further Human Factors validation."
This indicates that the "performance" considered for this submission relates to packaging and user interface (labeling/carton design), and the study conducted was a human factors/usability study, not a clinical performance study measuring accuracy or efficacy of a medical algorithm.
Therefore, I cannot populate the table or answer the specific questions related to acceptance criteria, AI/ML performance, and ground truth for a diagnostic or AI-powered device, as these details are not present and are not relevant to this type of device submission.
