Implantation tests are performed to evaluate the local pathological effects on living tissue, at both the gross level and microscopic level, after implantation of samples of medical devices or bio-materials.  The implant location is based on the clinical site of use.  Implant duration’s are based on the need to evaluate the tissue response over multiple intervals and along with the sample’s inertness and absorptive characteristics
