Abstract

Implantable material testing devices and method of testing materials in an animals are provided. In one embodiment, a method of testing a material in an animal includes associating the material with a retention frame to form a testing device. The retention frame movable between a first shape suited for insertion through a deployment instrument and a second shape suited for retention in the animal. The testing device is inserted in the first shape into the deployment instrument and is driven through the deployment instrument into the animal. Once in the animal, the testing device is permitted to assume the second shape so that the testing device is retained in the animal for a testing period. The testing device is removed from the animal after the testing period is complete, and the material is analyzed. The material may be analyzed for biofilm formation, encrustation, or degradation. The animal also may be analyzed for infection or other reactions to the material. Tissue may be collected from the animal, and the tissue may be analyzed.
