Medical device safety testing uses animals including dogs, pigs, and sheep to evaluate implants, surgical tools, and diagnostic equipment before human use, with specific welfare challenges distinct from pharmaceutical research.
Key Facts
Dogs are used in cardiac device testing because their heart size and anatomy approximates human cardiovascular systems
Pigs are the primary large animal model for surgical device testing due to organ size similarity to humans
Medical device animal testing falls under different regulatory frameworks than pharmaceutical testing in most countries
Implantable device testing involves surgical procedures and recovery periods that can extend weeks to months
Recovery care standards for large animals in device testing vary significantly between institutions
OECD test guidelines for implantable devices have fewer animal welfare refinements than pharmaceutical toxicology guidelines
Welfare Considerations
Medical device testing presents distinct welfare challenges from pharmaceutical research. Animals undergo surgical implantation procedures followed by recovery periods during which they must be managed with appropriate analgesia and wound care. The welfare standard of care during recovery is highly variable across testing facilities and subject to less regulatory scrutiny than pharmaceutical animal testing. A welfare-positive approach requires mandatory post-surgical pain management protocols, appropriate housing during recovery, and accelerated adoption of computational and in vitro models that can replace some device testing steps.
What You Can Do
Advocate for mandatory post-surgical pain management standards in medical device animal testing
Support development of validated computational and in vitro alternatives for device safety assessment
Engage with medical device companies about their animal use reduction commitments
Support regulatory harmonisation that recognises non-animal device safety data
