About Custom NX

Custom NX is designed to enable a more personalized approach to the treatment of arterial disease based on each patient's individual lesion characteristics. The Custom NX delivery system allows physicians to customize the length and diameter of the stent at the site of the lesion by enabling separation at each six-mm segment and allowing for the placement of up to 60 mm of stent. The stent is coated with Biolimus A9 and PLA, a biodegradable drug carrier.

The Custom NX DES System has not been approved for sale by any regulatory authority.
