Biocompatibility and Devices Research

Biocompatibility is the ability of an implant material to function in vivo without eliciting detrimental local or systemic responses in the body. Prior to their use in human fracture fixation, biomaterials undergo tissue and animal testing to determine their safety and efficacy.

Here at Comparative Biosciences, Inc. We offer a range of safety evaluation and biocompatibility services for medical devices.

Medical Devices Biocompatibility Testing – A Risk-Based Framework for Biocompatibility Assessment

What exactly is a “risk-based approach?” 

ISO 14971 defines the term “risk” as “the combination of the probability of occurrence of harm and the severity of that harm.” The standard defines harm primarily as physical injuries and damage to health, but it also includes harm to goods and to the environment. 

ISO 14971 is the key to effective risk management for medical devices.

ISO 14971 is the risk management standard for medical devices. This includes software as a medical device and in vitro diagnostic medical devices. It contains a structured approach for effective risk management. The risk-based approach adds the harm resulting from regulatory non-compliance and bureaucracy. It is about weighing the likelihood and the consequence of the identified risks and adapting the expenditure of resources accordingly. 

In Vivo Assays

  • Acute, systemic, subacute, chronic and carcinogenicity toxicity studies
  • Beuhler, Draize and Magnussen-Kligman maximization testing
  • Biocompatibility
  • Bone, joint,  and orthopedic
  • Contact lens testing, ISO-9394
  • Device-drug combinations
  • Device-stem cell combinations
  • Dermal, ocular, mucosal irritation testing
  • Bone, joint, and orthopedic
  • Long-term surgical implantation studies
  • Muscle, bone, subcutaneous and intradermal implantation
  • Topical, intracutaneous, ocular and primary skin irritation testing
  • Pyrogenicity testing

CBI has conducted numerous studies related to dural, amnionic, pericardial and other patches, coated films, sutures, matrices, osteoinduction materials, cartilage regeneration, morselized bone, spinal fusion, bone regeneration and tendon repair. These studies are often customized or unique experiments.
