Practice Perfection.

Improve patient outcomes by rehearsing surgeries on realistic 3D-printed models.

We're transforming preoperative care.

Each patient is unique, we strive to establish personalized medicine solutions for patients and physicians alike. Our Pre-Sure® (PRE-operative SUrgical REhearsal) models are made with soft synthetic polymers that mimic human tissue making them ideal for practicing incisions and sutures. They allow you to practice on a 3D printed, patient-specific replica before operating. Personalized patient care improves patient experience, maximizes safety and drives better outcomes.

Dr. Ward Shalash, Ph.D.

Principal Scientist

At Lazarus 3D, Dr. Shalash concentrates on advancing patient-specific medical devices through innovative R&D and collaborative work with leaders in healthcare. As a biomedical engineer, Dr. Shalash spent his career developing innovative solutions to enable cryopreservation of intervetebral discs and cartilage tissue from patients. Additionally, his work utilizing finite element analysis and MR imaging led to the development of an ML driven approach to determining the microenvironment in the intervertebral discs which has applications in guiding stem cell therapy treatments. As a scientist and entrepreneur, Dr. Shalash is very excited about the future of surgical care, where advances in medical imaging, AI, automation and 3D printing will drive a new standard of care where patient treatment is always delivered with confidence.
