Rampart Guardian Radiation Protection System Evaluated in EVAR Procedure

December 3, 2025— Rampart IC, a developer of radiation shielding for interventional suites, announced new data on the reduction in radiation exposure achieved using the Rampart Guardian system, a lead-free, total-body, total-team protection solution.

Patrick Muck, MD, presented the findings during the Radiation Safety, Devices, and Techniques session at the VEITHsymposium.

According to the company, Dr. Muck’s presentation included findings from the first endovascular aneurysm repair (EVAR) procedure performed without lead aprons using the Guardian system.

Rampart reported that the typical recorded operator and staff radiation exposure per EVAR case using the Rampart system is approximately 2 mRem. With an annual occupational limit of 5,000 mRem, staff could perform 2,500 cases per year before approaching the yearly limit, noted the company.

“These are complex cases with fluoro times of nearly 30 minutes,” commented Dr. Muck in Rampart’s press release. “It’s spectacular that we’re being protected to a level where we can safely and effectively come out of lead aprons.”

Dr. Muck further emphasized the limitations of conventional protective gear, noting that traditional lead aprons have insufficient coverage and can weigh up to 24 pounds.

“There’s a failure to lead aprons,” stated Dr. Muck. “They only cover 60% to 70% of the body, and they’re heavy. They cause orthopedic injuries and don’t protect our full body.”

He continued, “I really admire the Rampart system, or what I call barrier protection. Backed by two randomized trials and head-to-head data, Rampart is proven to provide superior protection. We utilize the Guardian as it’s ideal for peripheral and EVAR procedures. It’s easy to use, integrates into our procedural workflows flawlessly, and we can now shed the lead with barrier protection.”
