K953205 is an FDA 510(k) clearance for the CONSTANT CURRENT PERIPHERAL NERVE STIMULATOR NS272 (MODIFICATION). Classified as Stimulator, Nerve, Peripheral, Electric (product code KOI), Class II - Special Controls.

Submitted by Fisher &Paykel Healthcare , Ltd. (Auckland, New Zealand, NZ). The FDA issued a Cleared decision on May 23, 1996 after a review of 359 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.2775 - the FDA anesthesiology and respiratory 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Anesthesiology review framework, consistent with the majority of Class II 510(k) submissions.
