It is indicated for use in adult and adolescent populations to endoscopically dilate strictures of the alimentary tract.

The 3-Stage Balloon Dilation Catheter can provide 3 different sizes and gradually increasing diameters through controlled radial expansion. The specific balloon size is printed on the label of each package and catheter. The 3-Stage Balloon Dilation Catheter is designed to pass through the working channel of the endoscope, and its guidewire cavity can accommodate a 0.035inches (0.89mm diameter) guidewire. In the package, a 0.035inches (0.89mm diameter) guidewire is pre-installed in the guidewire cavity. There is a guidewire locking device connected to the guide wire hole of the catheter. The locking device will be in the "OFF" (closed) position when it leaves the factory. Only when the switch of the locking device is in the "ON" position can it be pushed or moved forward. The guide wire is removed from the catheter. After turning the switch to the "OFF" position, the guide wire will be fixed in the catheter.

This document details the FDA's 510(k) clearance for the VedDilator™ 3-Stage Balloon Dilation Catheter. It does not describe a study involving an AI/Machine Learning device or a diagnostic device. Therefore, the requested information regarding acceptance criteria and performance of an AI/ML-based device cannot be extracted from this document.

The document focuses on the substantial equivalence of this medical device (a physical catheter) to a predicate device based on non-clinical performance testing and biocompatibility.

Here's why the requested information cannot be provided from this document:

• No AI/Machine Learning: The device is a physical catheter, not a software or AI-based diagnostic tool.
• No Diagnostic Performance Study: The document lists non-clinical bench testing for physical characteristics (e.g., burst pressure, maneuverability, sterility) and biocompatibility, not diagnostic performance metrics like accuracy, sensitivity, or specificity.
• No Human Reader Study: Since it's a physical device, there's no concept of human readers or MRMC studies.
• No Ground Truth Establishment: The "ground truth" in this context refers to the physical properties of the device, measured through standard engineering tests, not a clinical diagnosis established by experts.

Summary of available information (not directly addressing the prompt's request for AI/ML device performance):

• Device: VedDilator™ 3-Stage Balloon Dilation Catheter
• Purpose: To endoscopically dilate strictures of the alimentary tract.
• Study Type: Non-clinical bench testing and biocompatibility testing for substantial equivalence to a predicate device (K112994).
• No Clinical Study: Section 7 explicitly states, "No clinical study is included in this submission."
• Test Performed (Non-Clinical): Rated burst pressure test, Balloon tightness test, Connection firmness test, Maneuverability test, X-ray development performance test, Sterility test, Residual amount of ethylene oxide Test, Balloon fatigue Test, Burst Test of Guidewire, Bend Test of Guidewire, Connection Strength Test of Guidewire, Corrosion resistance Test of Guidewire.
• Biocompatibility Tests: Cytotoxicity, Irritation, Sensitization, Acute Systemic Toxicity, Material mediated pyrogenicity.
• Conclusion: The device meets design specifications and demonstrates substantial equivalence to the predicate device based on these non-clinical tests.
