K950809 is an FDA 510(k) clearance for the VISION-SCIENCES DISPOSABLE ENDOSHEATH FOR FLEXIBLE NASOPHARYNGO-LARYNGOSCOPES. Classified as Nasopharyngoscope (flexible Or Rigid) (product code EOB), Class II - Special Controls.

Submitted by Vision-Sciences, Inc. (Natick, US). The FDA issued a Cleared decision on August 5, 1996 after a review of 530 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Ear, Nose, Throat FDA review panel, regulated under 21 CFR 874.4760 - the FDA ear, nose and throat device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Ear, Nose, Throat submissions.
