XO Score is a new type of scoring and cutting technology that enables low-pressure lesion dilatation and vessel prep with a broad range of standard off-the-shelf PTA balloons. Scoring sheaths have the ability to deliver enhanced angioplasty with basic balloons while addressing the cost and performance limitations of traditional scoring or cutting technologies.

“We need novel, safe and appropriately aggressive vessel prep devices to continue fighting the increasingly difficult stenotic lesions encountered in CLI patients,” said Jihad Mustapha, MD CLI specialist at Advanced Cardiac & Vascular Center, Grand Rapids, MI. “XO Score helps fill that unmet need by enabling variable scoring depths and improved pushability which are essential when dealing with tough calcifications.”

The XO Score incorporates a unique one-piece metal-alloy exoskeleton design which adapts to the shape, size, and length of the PTA balloon used inside it. This approach lets physicians select the PTA platform of their choice for use in conjunction with XO Score, potentially reducing inventory and procedural costs. Future ultra-low-profile over-the-wire and rapid-exchange versions are under development for smaller vessel and coronary use.
