The world leader in preclinical, interventional and surgical research

NAMSA is proud to offer interventional and surgical study capabilities in a range of locations across the globe. Working in our state-of-the-art laboratories, NAMSA’s highly-trained experts utilize a broad range of trusted In Vivo models and analysis tools, including five (5) Siemens Cath Labs and a 128-slice CT Scanner, among other advanced technologies, to deliver study results in an accelerated, cost-efficient manner.

Combining decades of experience in therapy delivery systems and implantable medical device research, NAMSA has the distinction of serving as the industry’s premier destination for preclinical interventional research. Our Surgeons/Interventionalists are Doctors of Veterinary Medicine or Academy of Surgical Research certified and have trained with some of the most prominent doctors and researchers in the field.

Although NAMSA’s surgical staff is equipped with all the necessary tools to support your entire procedure, we also provide à la carte services to support your preclinical needs. Interested in having your key opinion leader (KOL) or design team personnel work with your product? No problem. The NAMSA team will fill in the necessary gaps in procedure roles so that your staff can concentrate on their duties during the implant or treatment procedure.

All of NAMSA’s surgical suites are maintained to hospital standards. Every suite features temperature and humidity control, with HEPA filtration for a full aseptic surgical field.

We also understand the criticality of complying with methods and regulations within the European Committee for Standardization (CEN), U.S. Food and Drug Administration (FDA) and other international guidelines to provide Sponsors with the most reliable, accurate outcomes in industry.

Pathology is the gold standard for the evaluation of medical device performance and safety. The NAMSA pathology lab is designed for high volume to meet and exceed all of your tissue and device collection requirements. We operate a fully equipped, 5,000 square foot histopathology and SEM laboratory in our main facility.

The NAMSA pathology lab is operated by Board Certified Histotechnicians and has both Board Certified Veterinary Pathologists and MD, PhD Pathologists who oversee gross necropsies, interpret histopathology slides and write reports evaluating the safety of products. The lab also has advanced equipment for the precise sectioning of all medical devices, using paraffin, plastic thin microtomy, plastic EXAKT ground sectioning, and SEM techniques.

NAMSA offers an array of services for drug discovery programs including efficacy studies, pharmacokinetic (PK) assessments, as well as discovery and GLP toxicology services. We are pleased to offer these services in both rodent and various models, while combining our bioanalytical and histopathology capabilities to centralize your research in our state-of-the-art facilities.

With a focus on pain pharmacology, NAMSA brings years of expertise in behavioral pharmacology to bear on to your projects, helping you prioritize leads and select development candidates. At NAMSA, we understand the importance of delivering quality data as rapidly as possible. Our turnaround times are unmatched and our rigorous approach to positive controls ensures that you will finish with quality data on which to base your crucial go/no-go decisions.

We also understand that the development of novel therapeutics requires the development and validation of novel models and assessment methodologies. When you have chosen your development candidates, let us continue to help with your program needs through our Toxicology Services. From dose-ranging on through acute and chronic studies, and from mice to canines, NAMSA can assist you establish safety and tolerability profiles of your lead molecules.

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.

Training
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.
