Intended Use

The WATCHMAN FXD Curve™ Access System is intended to provide vascular and transseptal access for the WATCHMAN FLX Left Atrial Appendage Closure Device with Delivery System.

Device Description

The Boston Scientific WATCHMAN FXD Curve™ Access System is composed of an Access Sheath and Dilator. The WATCHMAN FXD Curve Access System is used to provide vascular and transseptal access for WATCHMAN™ FLX™ Left Atrial Appendage Closure Device with Delivery System. The WATCHMAN FXD Curve Access System will be used by interventional cardiologists and/or electrophysiologists who are trained in percutaneous and transseptal procedures.

AI/ML Overview

The provided text is a 510(k) summary for the WATCHMAN FXD Curve™ Access System. It details the device's description, indications for use, comparison to a predicate device, and the non-clinical performance data supporting its substantial equivalence.

However, the provided text does not describe a study involving an AI/software device that requires intricate ground truth establishment, MRMC studies, or training/test set data provenance as requested in the prompt.

The performance data listed are for a physical medical device (catheter) and include:

  • Dimensional Characterization
  • Curve Shape
  • Proximal and Distal Marker Location
  • Sheath Force Transmission
  • Kink Resistance
  • Tip Deflection
  • Torqueability
  • Radiopacity
  • Tensile
  • Surface
  • Leak-Free Conduits
  • Pressure Retention
  • Particulates
  • Access Sheath Cap Detachment Force
  • Access System Smooth Transition
  • Biocompatibility tests (Cytotoxicity, Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Complement Activation, Materials Mediated Pyrogenicity, Hemolysis Direct Contact, Hemolysis Extract Method, In Vitro Platelet and Leukocyte Count, Partial Thromboplastin Time)

The text explicitly states: "Clinical evaluation was not required for this device." This confirms that there was no human-in-the-loop study with human readers or AI involved that would necessitate the detailed categories requested in your prompt.

Therefore, I cannot extract the information requested regarding acceptance criteria and a study proving an AI device meets those criteria, as the document describes a physical medical device (catheter) cleared through the 510(k) process based on non-clinical performance testing and substantial equivalence to a predicate device, not an AI or software-as-a-medical-device (SaMD) study.
