Life-saving AAJT-S by Compression Works Earns MDR Certification

Compression Works, Inc., manufacturers of the Abdominal Aortic & Junctional Tourniquet – Stabilized (AAJT-S), announces the certification of their life-saving medical device using the rigorous MDR (Medical Device Regulation (EU) 2017/745) process recently introduced and required throughout the EU and the UK.image Newsroom  - Compression Works

The Medical Device Regulation (MDR), adopted in April 2017, changes the European legal framework for medical devices and introduces new principal and supportive responsibilities for the European Union (EU) and for national competent authorities in the assessment of certain categories of products. The Regulation entered into force in May 2017 and had a staggered transitional period.

To support the implementation of the MDR, updated guidance on quality requirements for medical devices was prepared, and this new regulatory designation replaces the existing directives for medical devices (93/42/EEC and 90/385/EEC).

“This is a significant undertaking,” explained Trey Thorsen of O'Connell & Myers, Regulatory Consultant for Compression Works, Inc. “The requirements for this designation are very thorough, and the bar is set quite high. There are very few companies in the hemorrhage control space or the medical device industry, for that matter, that have cleared this hurdle, and we are very proud to be able to claim this distinction.”

The AAJT-S is used to stop non-compressible hemorrhage in junctional areas where traditional tourniquets are difficult to place and where the bleeding is most severe. The AAJT-S is also the only FDA-cleared and CE-marked medical device for the prevention of pelvic bleeding and is used in the military and first responder communities at the point of injury to stabilize the patient so that they can be transported to definitive care.

Innovations in Hemorrhage Control Method | Inside the World of Tactical Medicine Condition | Podcast

Step into the vanguard of battlefield medicine with Dr. John M. Croushorn, an engineer-turned-emergency physician whose innovations are redefining trauma treatment. From his pivotal career switch of joining Army Medicine post-9/11 to creating the Abdominal Aortic Junctional Tourniquet (AAJT-S), this episode weaves together the personal and the technical, providing an intimate look at the challenges and triumphs of military medicine.

As we converse with Dr. Croushorn, you'll be transported to the front lines of tactical emergency medical solutions, where the origins of such practices in the military and law enforcement laid the groundwork for today's life-saving techniques. Discover the birth of the AAJT-S, spurred by tragedy and necessity, and how a chance encounter with a Special Forces Medic brought the device's development full circle. This narrative captures the essence of innovation - where creativity meets critical needs, and every step in the design process can mean the difference between life and death. The trenches of tactical medicine are filled with stories of lives saved and legacies forged, and each tale tightens the bond between trauma care advancements and those who stand ready at the front lines.

Dr. Croushorn continues to pull back the curtain on the dynamic field of military medicine, guiding us through the application of junctional tourniquets and their profound impact on saving lives in pre-hospital scenarios. We'll also cast an eye to the future, examining ongoing research and the global implications of these medical advancements. Hear tales of the AAJT-S's deployment in diverse environments, from the deserts of the Middle East to the conflict in Ukraine, and learn how this technology is not just a tool but a testament to human resilience and the relentless pursuit of advancing trauma treatment.
