K840900 is an FDA 510(k) clearance for the PORTA PAK 90. 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 June 11, 1984 after a review of 104 days - within the typical 510(k) review window.

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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Cardiovascular review framework, consistent with the majority of Class II 510(k) submissions.
