Submitted by Philips Medical Systems (Bothell, US). The FDA issued a Cleared decision on January 23, 2015 after a review of 422 days - an unusually long review period, suggesting complex equivalence evaluation.

The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.
