XO Score scoring sheath platform wins medical design award

Transit Scientific’s XO Score device inflated with a standard 4×40 PTA balloon

Transit Scientific today announced that its XO Score scoring sheath platform has been named a winner in the 2021 Medical Design Excellence Awards (MDEA). The MDEA is a premier design competition in the medtech industry, recognising significant achievements in medical product design and engineering that improve the quality of healthcare delivery and accessibility.

“We are honoured that our XO Score platform has been recognised by the MDEA organisation,” said Greg Method, president of Transit Scientific. “We designed XO Score as a novel way to expand angioplasty-based tools available to physicians for treatment of peripheral arterial disease (PAD), chronic limb-threatening ischaemia (CLTI), and end-stage renal disease (ESRD). The award is a testament to the dedication and hard work of the team at Transit Scientific and reflects our commitment to bringing new technologies to market for the advancement of patient care.”

XO Score is a novel scoring sheath that works by fitting over physician selected off-the-shelf percutaneous transluminal angioplasty (PTA) balloons to enable scoring and cutting vessel preparation. The unique balloon-expandable scoring element enables a single XO Score device to work with a large range of balloon diameters and lengths for in-procedure adaptability. XO Score has been used successfully to dilate calcified and fibrous lesions during a multisite, multiuser limited market release.

“XO Score’s proprietary rotating strut design ensures the device remains low profile for tracking to and from the treatment site”, continued Method. “The ability to engage the wall and dilate at a low inflation pressure has yielded great outcomes in a broad range of PTA-resistant lesions.”

The device is currently indicated for treatment of peripheral vascular stenosis including haemodialysis fistulas and grafts.
