The Merit Prelude Wave Hydrophilic Sheath Introducer is intended to provide access and facilitate the percutaneous introduction of various devices into veins and/or arteries, including but not limited to the radial artery, while maintaining hemostasis for a variety of diagnostic and therapeutic procedures.
The access needle with inner metal needle and outer plastic cannula is used to gain access to the vein or artery for placement of guidewires.
The Prelude Wave™ Hydrophilic Sheath Introducer consists of a sheath introducer with compatible vessel dilator that snaps securely into the sheath introducer hub. The sheath hub contains an integral hemostasis valve. The sheath tubing is coated with a hydrophilic coating. A sidearm is affixed to the sheath hub and has a 3-way stopcock at its proximal end. The Prelude Wave™ Hydrophilic Sheath Introducer is available in 11cm and 23cm lengths, (French sizes 4F, 5F, 6F and 7F) and is designed to accept 0.018", 0.021" and 0.025" diameter guidewires. The Prelude Wave™ Hydrophilic Sheath Introducer is marketed with any of the following components, depending on the product configuration: guidewire, metal access needle, access needle with inner metal needle and outer plastic cannula and SnapFix™ securement device.
The provided FDA 510(k) clearance letter and summary for the Prelude Wave Hydrophilic Sheath Introducer (K250909) do not contain the specific information requested in the prompt regarding acceptance criteria, device performance, sample sizes for training and testing, expert qualifications, or detailed descriptions of ground truth establishment for an AI/ML medical device.
This document describes a traditional medical device (a catheter introducer), not an AI/ML-based device. Therefore, the types of studies and acceptance criteria typically associated with AI/ML device clearance (as outlined in your prompt questions) are not applicable here.
The document primarily focuses on:
- Substantial Equivalence: Demonstrating that the new device is as safe and effective as a legally marketed predicate device (Prelude IDEAL Hydrophilic Sheath Introducer, K173750). This is a common pathway for traditional medical devices.
- Performance Testing: Verification and validation studies to ensure the device meets its specifications and performs as intended, based on established international standards (ISO 10555-1, EN ISO 11070, ISO 10993-1, ISO 14971). These tests are standard for physical medical devices and include mechanical, functional, and biocompatibility assessments.
- Design Changes: Highlighting minor design modifications from the predicate, such as sheath material, sheath/dilator tip fit, and inclusion of an adhesive fixation device.
Therefore, I cannot populate the table or answer the specific questions about AI/ML device study parameters (like MRMC, standalone AI performance, expert labeling, training data) based on the provided text. The provided text simply does not contain this information because it's a submission for a physical medical device, not an AI software.
