Transit Scientific’s XO Cross Catheter Platform Used to Treat Complex CLI With Pedal Artery Retrograde Access

August 1, 2022—Transit Scientific reported that multiple peripheral vascular procedures were performed with the company’s XO Cross catheter platform using pedal retrograde access to treat complex critical limb ischemia (CLI). The nontapered 2-F XO Cross 14 microcatheter, available in 90-, 135-, and 17-cm lengths, is designed to facilitate guidewire support, guidewire exchange, and contrast media injection during complex peripheral vascular interventions.

The nontapered device’s metal-alloy and polymer construction is designed to provide high fatigue resistance against tough lesions found in late-stage peripheral artery disease and CLI. The pushability, trackability, flexibility, and torque response allow access to challenging lesions and complex anatomy.

Interventional cardiologist George Adams, MD, who is Director, Cardiovascular and Peripheral Vascular Research at UNC REX Healthcare in Raleigh, North Carolina, commented in the company’s press release, “2-F 014 catheter-guidewire systems are an important tool for pedal and below-the-knee interventions. The XO Cross incorporates a nontapered torquable shaft design, which supports a smaller and less invasive access site from below. Tools like these can help broaden options for approaches and access techniques in CLI patients.”

In the press release, Richard Saxon, MD, of Tri-City Medical Center in Oceanside, California, reported, “A patient presented with trifurcation disease and severe calcifications in the superficial femoral artery, popliteal, and the posterior tibial artery. The low-profile and pushability of the XO Cross 14 enabled pedal retrograde access following failed crossing and wire from above. A second XO Cross 14 (135 cm) was used from above to support a flossing technique and subsequent angioplasty treatment. The unique nontapered design of the XO Cross lends itself well to challenging limb salvage procedures that often require multiple access sites and different approaches to achieve a good outcome.”
