NAMSA’s preclinical, interventional and surgical research services provide support for all model types, treatments and implant requirements. Our highly sought-after teams are expert at helping Sponsors utilize data to bridge preclinical safety endpoints to proposed clinical endpoints, allowing clinical labs to standardize measurements and obtain expert interpretations of results.

Cutting edge imaging technology is at the heart of all research processes, including diagnostic imaging for visualizing implants, diagnosing defects or disease, and documenting research outcomes. Our surgical staff, Doctors of Veterinary Medicine and/or Academy of Surgical Research-certified, are equipped with the necessary tools to support your entire procedure. Our teams also provide the opportunity to fill in specific gaps in procedure roles so you may focus on duties during implant or treatment procedures.

Some of our most requested therapeutic research areas include: Cardiovascular, Dental, Dermal, Electrophysiology, Gastrointestinal, Neuromodulation, Orthopedics, Pulmonary, Urogential, Wound Healing, and many others.

Bioskills Cadaver and Simulation Labs

Performing human cadaver studies since 2006, NAMSA is an approved human cadaver lab site authorized to perform device evaluations. We provide whole body cadavers as well as partial cadavers or various tissues. Combining our access to tissues with our equipment and expertise allows us to provide device evaluations at the highest levels. We also provide in vivo tissue for use in wet lab device evaluations.

The FDA’s expectations for physician training and human factors testing within the medical device arena are continuing to grow. It’s more important than ever to bring physicians, engineers, and technical staff into the simulation lab to learn and train on devices. It is essential that they be familiar with these complex systems, as they accurately simulate the feel and rigors of an operating room (OR) or catheterization lab. NAMSA’s facilities can fulfill this need, as well as host or train your internal trainers with expertise from our staff.
