Oct. 7, 2025 — Cagent Vascular has announced the commercial launch of the Serranator PTA Serration Balloon Catheter in 7.0 mm and 8.0 mm diameters. This expansion brings the proven benefits of serration technology to larger vessels, including the iliac, SFA and other challenging peripheral anatomies.
The Serranator combines balloon angioplasty with embedded serration elements designed to create multiple longitudinal lines of interrupted scoring along the arterial wall. This approach provides predictable vessel expansion while minimizing barotrauma and optimizing luminal gain. The availability of larger diameters allows physicians to apply serration technology across a wider spectrum of disease presentations, including areas in the iliac arteries and arteriovenous fistula.
“The addition of the 7.0 mm and 8.0 mm Serranator balloons gives us new options for treating patients with large vessel peripheral artery disease,” said Neil Poulsen, MD of Clara Maass Medical Center in Belleville, NJ. “I’ve found serration technology to provide controlled, effective expansion with less vessel trauma and recoil compared to conventional angioplasty. Having these larger sizes available gives us a versatile tool that can be applied in real-world cases where options have historically been limited.”
With the expanded portfolio, the Serranator now covers a full range of vessel sizes — from below-the-knee to large proximal arteries and arteriovenous fistula — further positioning the technology as a versatile tool for comprehensive PAD treatment strategies.
“This milestone reflects our commitment to addressing unmet needs in peripheral vascular care,” said Paul Wilson, Chief Commercial Officer. “Physicians asked us for larger sizes, and we are proud to deliver solutions that continue to support both every day and highly complex interventions.”
The 7.0 mm and 8.0 mm Serranator sizes are now commercially available in the United States.
