Transit Scientific’s XO Cross Catheter Platform Approved in Europe for Use in Peripheral Vasculature

March 17, 2021—Transit Scientific announced that European CE Mark approval was granted for its XO Cross microcatheter platform. The company will launch the 2-F XO Cross 14 microcath, the 2.6-F XO Cross 18 microcath, and the 3.8-F XO Cross 35 support catheter in Europe over the coming months.

Transit Scientific advised that it has completed a successful multisite multiuser limited release in the United States for the XO Cross. The company announced FDA clearance of XO Cross in May 2020.

According to the company, XO Cross is a comprehensive support catheter platform available in 90-, 135-, 150-, and 175-cm working lengths for use with standard 0.010-, 0.018-, and 0.035-inch guidewires. The longer 175-cm versions are designed to support radial artery to peripheral access or pedal access from a contralateral femoral approach.

The XO Cross platform is designed to deliver new levels of pushability, trackability, and torque response for improved access in challenging peripheral lesions. With its nontapered, metal-alloy, and polymer construction, the system delivers high fatigue-resistance for tackling tough calcium and plaque found in patients with late-stage peripheral artery disease and critical limb ischemia.

“XO Cross incorporates a unique nontapered design that gives it guidewire-like 1:1 torque response,” commented George Adams, MD, in the company’s announcement. “The low-profile 2-F XO Cross enabled easy access and wire support for a pedal retrograde approach through a 2.9-F micropuncture sheath rather than needing a larger 4-F introducer.” Dr. Adams is an Interventional Cardiologist at UNC REX Healthcare in Raleigh, North Carolina.

Eric Dippel, MD, added, “We encounter increasingly complex, difficult lesions that require new sophisticated microcath technologies and approaches. XO Cross helps fill that need by enabling better control, response, and tip shapeability for improved wire support and crossing.” Dr. Dippel is an Interventional Cardiologist at Vascular Institute of the Midwest in Davenport, Iowa.
