Venous Window Needle Guide

Gastroenterology, Urology

View full classification →

The Venous Window Needle Guide is a gastrointestinal and urology device used as an access accessory on arteriovenous fistulas (AVF) for hemodialysis procedures using a constant site (buttonhole) cannulation technique, guiding needle insertion to the same location at each treatment session to maintain fistula integrity. It falls under the Gastroenterology and Urology medical specialty and is classified as a Class 2 device under regulation 876.5540, requiring 510(k) premarket notification. It is flagged as both an implant and life-sustaining, reflecting its role in maintaining vascular access for patients dependent on hemodialysis.

What is a Predicate Device?

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.

Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.

Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
