Advancing Surgical Safety through Nature-Inspired Innovation

Abdominal surgery today saves countless lives and restores health for millions, yet one of its most persistent challenges continues long after the operation—postoperative adhesions. These internal scar tissues can lead to chronic pain, digestive disorders and infertility in women, and in severe cases, bowel obstruction requiring additional surgery.

PlantTec Medical is redefining surgical safety with 4DryField^® PH, a natural starch-based material that ensures clean hemostasis and protects tissue from postoperative adhesions.

4DryField^®PH is built from modified plant-based polysaccharides that are highly biocompatible, non-allergenic and free from synthetic or animal-derived substances. It combines natural purity with clinical performance for improved quality of life for every patient. Applied as a fine powder, it instantly stops surgical bleeding and when transformed into a a soft gel, it shields the tissue physically and minimizes the risk of adhesion formation. Its composition is safely degraded within the body, leaving no toxic residues.

“Our philosophy is built on our belief that true innovation must serve patients and the environment,” says Ellen Laas, managing director.

During reoperations, adhesions also extend surgical time, increase blood loss and elevate injury risk. With nearly half of Germany’s population expected to undergo abdominal surgery in their lifetime, the need for reliable adhesion prevention has never been more critical.

Studies show that 4DryField^® PH reduces postoperative adhesions by up to 85% and helps patients recover faster. In gynecological procedures, it improves fertility outcomes, while in pediatric cardiac surgeries it shortens operation time and simplifies tissue separation. Numerous experimental and clinical publications have demonstrated its efficacy across fields such as visceral surgery, urology, orthopedics and burn surgery, confirming its adaptability and consistency in real-world surgical settings.

Used in over 50 countries worldwide, 4DryField^® PH adapts seamlessly to diverse surgical needs. Its dual function has made it a trusted solution among surgeons seeking both precision and safety.

Turning Surgical Insight into Real-World Solutions

Guided by the principle of “From Practice for Practice,” PlantTec Medical builds innovation on surgical expertise and collaboration with medical professionals. Under the leadership of Prof. Dr. Joachim Laas, former cardiothoracic surgeon and scientific director, the company transforms real clinical challenges into practical, sustainable medical products.

Prof. Laas is a member of the American Society of Thoracic Surgeons and the German Society for Thoracic, Cardiac, and Vascular Surgery. He has also served as editor and co-editor for leading international journals, including The Journal of Thoracic and Cardiovascular Surgery and the European Journal of Cardio-Thoracic Surgery. His decades of surgical and academic experience continue to guide PlantTec’s scientific direction and commitment to evidence-based development.

An interdisciplinary team spanning medicine, biology, engineering and materials science works alongside him to combine natural raw materials with advanced medical technology. Their goal is to create solutions that are effective, sustainable and safe.

Regulatory Excellence Driving Reliable Surgical Innovation

Every stage of product development follows strict regulatory and quality standards. 4DryField^® PH is certified under European and international frameworks, including the Medical Device Regulation (MDR) and CE marking. A dedicated regulatory team ensures compliance through continuous audits, process optimization and staff training while proactively monitoring global regulations to maintain full alignment with evolving standards. The commitment to quality safeguards product reliability and reinforces confidence among healthcare providers worldwide.

PlantTec Medical also prioritizes long-term collaboration. Clients value the company’s openness, rapid response and personalized technical support, qualities that help healthcare providers work confidently in high-pressure surgical environments. Surgeons benefit from hands-on procedural guidance and training, ensuring seamless integration of 4DryField PH into diverse surgical disciplines.

By combining renewable, plant-based materials with environmentally responsible manufacturing, PlantTec Medical demonstrates that innovation, patient safety and sustainability can go hand in hand. The company’s mission is clear: to develop technologies that deliver practical value for patients and surgeons, while ensuring global accessibility and affordability.
