Why You Should Consider Cadaveric Training When Conducting Medical Device R&D
Cadaveric training, sometimes referred to as cadaveric testing, is a process that uses human cadavers for research and training purposes. For medical device research and development (R&D), cadaveric training can provide a number of benefits.
In this article, we’ll explore why cadaveric training is often used in the R&D process.
Provides a Better Understanding of Human Anatomy
Cadaveric training provides trainees with a better understanding of human anatomy and the device’s effects on the body. Researchers gain more intimate knowledge of the body’s complex systems and how the device may be used most effectively to solve problems.
For cosmetic procedures like Botox, for example, cadaveric training allows trainees to observe and practice injection techniques. Gaining a better understanding of the facial muscles, blood vessels and nerves allows researchers to pinpoint the right placement for Botox injections to achieve the desired outcome.
Because cadavers are an accurate representation of human anatomy, researchers can perform more accurate assessments of the device’s performance along with anatomical challenges that may hinder the device’s use.
Evaluation of Tissue Behavior and Response
Through cadaveric training, researchers can observe and evaluate tissue response and behavior when interacting with the medical device, including tissue:
Strength
Elasticity
Response to forces and loads
Having the opportunity to evaluate and observe these effects first-hand allows researchers to optimize the design and function of their medical devices.
Controlled Device Testing
Cadaveric training provides researchers with an opportunity to assess the effectiveness and functionality of a medical device in a more controlled environment.
Using or implanting the device on cadaveric tissue allows researchers to:
Identify potential design flaws early on
Evaluate the device’s performance
Develop new design iterations to address safety issues and improve effectiveness
An Ethical Alternative
Although cadaveric training in itself has its own set of ethical concerns, it does provide an alternative to live experimentation and animal testing.
Cadavers can be obtained in an ethical manner through body donation programs, helping preserve human dignity while enabling research and development.
Cadavers May Be Used Multiple Times
In some cases, cadavers may be used multiple times for more rigorous testing. Thiel-embalmed cadavers, for example, can be used several times over a longer period of time without the need for refreezing and defrosting. This can allow you to make a direct comparison between products.
Move the Development Process Forward
Data and insights gained from cadaveric training can aid in the development of medical devices and guide clinical trials. This process can help ensure that products are optimized for human use and may even speed up the timeline for obtaining regulatory approval.
Final Thoughts
Cadaveric training can play an important role in medical device research and development. However, there are limitations. Cadavers are no substitute for clinical trials and in vivo studies. Data and feedback from living patients are still crucial to the development process and ensuring that medical devices are safe for human use.
With that said, cadaveric training still provides valuable insights and data that contribute to the development of safer and more effective medical devices. Improved efficacy and safety ultimately lead to better patient outcomes.
