K833751 is an FDA 510(k) clearance for the PORTA PULSE III #D320. Classified as Dc-defibrillator, Low-energy, (including Paddles) (product code LDD), Class II - Special Controls.

Submitted by Medical Research Laboratories, Inc. (Mchenry, US). The FDA issued a Cleared decision on January 11, 1984 after a review of 77 days - a notably fast clearance cycle.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.5300 - the FDA cardiovascular device oversight framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
