MINNEAPOLIS, Oct. 22, 2026 (GLOBE NEWSWIRE) - Egg Medical announced today that its prospective research findings on the EggNest Enhanced Radiation Protection Device (ERPD) have been successfully published in the Journal of the American Heart Association (JAHA). This real-world clinical study was conducted at The Christ Hospital in Cincinnati, Ohio, and the results confirm that, with this radiation protection solution, interventional operating room staff can safely perform procedures without wearing heavy personal lead aprons.
Further validating these clinical research findings from a practical application perspective, the Texas Department of State Health Services recently granted a state-level radiation regulatory exception to Methodist Healthcare System of San Antonio.
Dr. Santiago Garcia, interventional cardiologist at The Christ Hospital and principal investigator of the study, stated: "The EggNest system provides protection for the entire team, allowing everyone the choice to work without lead aprons or to wear ultra-light lead aprons that feel as light as a vest. These comprehensive and detailed data provide the interventional team with an evidence-based pathway to significantly reduce musculoskeletal burden while improving radiation safety levels."
Core Research Findings Published in JAHA
Dose Reduction Without Lead Aprons When using standard protective equipment, the estimated annual neck dose for the primary operator was 86.7 mRem; with the EggNest Complete, this value dropped sharply to 25.5 mRem (p < 0.001). CDC Data Reference: A 5-6 hour flight involves a radiation exposure of approximately 3.5 mRem.
Extremely Low Exposure for All Personnel After using the EggNest Complete ERPD, the total effective dose for all operating room personnel, including the primary operator, instrument assistant, and circulating nurse, was only 1% of the ICRP annual limit (5,000 mRem).
Performance with Ultra-Light Lead Aprons When the EggNest ERPD is paired with ultra-light (0.125 mm) lead aprons, the annualized radiation dose is significantly lower than the "traditional heavy (0.5 mm) lead apron + standard protection" regimen. With standard protection paired with a 0.5 mm lead apron, the primary operator's annualized EDE-1 dose was 51.4 mRem; with the EggNest Complete paired with a 0.125 mm ultra-light lead apron, this value was only 1.4 mRem (p < 0.001).
Dr. Tim Henry, Medical Director of The Carl and Edyth Lindner Center for Research and Education at The Christ Hospital and former SCAI President, stated: "The radiation reduction brought by EggNest fundamentally changes how we ensure operating room safety—I can now work with peace of mind even without wearing a lead apron. This clears the path for operators and staff towards a healthier, more sustainable future."
Achieving Lead-Free Work Responsibly Egg Medical is responsibly achieving lead-free work (Lead-Free, Responsibly) with a flexible and safety-first philosophy. The needs of modern interventional operating rooms vary, and the EggNest technology is designed to support "optional lead-free" workflows under the premise of regulatory approval, rather than mandating a single operational standard.
