Surgical Capabilities

American Preclinical Services has an extensive surgical program to meet all of your model development, treatment, and/or implant requirements. Our surgeons 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 APS' surgical staff is experienced and equipped with all the necessary tools to support your entire procedure, we also provide ala 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 APS team will fill in the necessary gaps in procedure roles to allow your staff to concentrate on their duties during the implant or treatment procedure.
