It seems that the FDA is moving forward to update their overall medical device approval process.

Manufactures currently have essentially been able to expedite the approval process if they could prove that their new product was substantially equivalent to a predicate.
This new announcement is encouraging companies to base new products on devices that are no older than ten years.
It seems that 20% of products cleared through the 510(k) pathway are based on a predicate device that is more than ten years old.
It appears that the FDA has plans to finalize it's guidance on establishing an alternative accelerated pathway in 2019.
