The VersaCross Connect™ Transseptal Dilator is indicated for use in procedures where access to the left atrium via the transseptal technique is desired.

The subject VersaCross Connect™ Transseptal Dilator is a single-use device that is supplied sterile to the user. The subject VersaCross Connect™ Transseptal Dilator represents modifications made to the dilator component of the legally marketed VersaCross Connect™ Transseptal Dilator (K220414) (comprising of a dilator and J-tipped guidewire). A guidewire is not supplied with the subject device. However, the end user can use a separately cleared compatible 0.035″ quidewire. The VersaCross Connect™ Transseptal Dilator is designed for safe and easy catheterization and angiography of specific heart chambers and locations. The dilator provides torque control and is flexible. The dilator features a tapered tip and a shaft that can be reshaped manually. The echogenic shaft and tip and radiopaque tip maximize visualization of the dilator during manipulation in procedures. The dilator can be used with separately cleared compatible access sheaths such as CARTO VIZIGO™ Bi-Directional Guiding Sheath (K231412). The dilator provides support and helps guide separately cleared compatible transseptal wires to the atrial septum for puncture. The dilator subsequently dilates the atrial septal defect to enable larger diameter devices to cross the septum.

The provided document is an FDA 510(k) clearance letter for the VersaCross Connect™ Transseptal Dilator. It primarily focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance testing.

Crucially, this document does not describe a study involving "acceptance criteria" for an AI/ML powered device, nor does it detail a study proving such a device meets these criteria.

The device in question, the VersaCross Connect™ Transseptal Dilator, is a mechanical medical device (a vessel dilator), not an AI/ML-powered one. The testing described is typical for a mechanical device and includes:

• Mechanical Testing: Torque Transmission, Torque Withstand, Flexural Rigidity, Shapeability, Curve Retention, Hub-Shaft Tensile, Tip to Tip Cap Cantilever and Tensile, Clamshell Tensile, Clamshell Cantilever.
• General Physical Testing: Luer Tests, Air and Liquid Leakage Tests, Corrosion Test.
• System Verification Testing: Compatibility Test, Snap Force Test.
• Biocompatibility Verification: Evaluated through adopted biological data of the predicate device (K220414).
• Sterilization Verification: Ethylene Oxide sterilization to a SAL of 10-6.
• Pyrogen Testing: Limulus Amoebocyte Lysate (LAL) testing.
• Packaging Verification: Ship testing and sterile barrier integrity.
• Benchtop Validation: To validate performance during normal intended use.

Therefore, I cannot extract the information required to populate the requested table and answer the questions about AI/ML device acceptance criteria and study details from the provided text.

The document states: "The proposed VersaCross Connect™ Transseptal Dilator met all test requirements as specified by applicable standards and test protocols. The verification and validation activities for safety and effectiveness, along with the testing completed for the design changes demonstrated the subject device meets its intended use and is as safe, as effective, and performs in a manner that is substantially equivalent to the predicate device." This is the general statement of compliance, but it does not provide specific acceptance criteria values or performance metrics in a tabulated format that would be relevant for an AI/ML device.
