Customized Testing for Medical Implants
In addition to standard-based testing, customized, product-specific test concepts for implants are becoming increasingly important. They enable the targeted evaluation of specific designs, materials, and clinical requirements that cannot be fully addressed by standards alone. This results in testing strategies precisely tailored to the respective product and its risk profile.
One example is breast implant-specific material testing, which is designed to address the unique properties of silicone implants. This includes shape stability testing, which evaluates whether the implant maintains its geometry under mechanical stress. In addition, peel testing between the filler material and the shell assesses the adhesion strength between the outer shell and the filling material to prevent delamination.
Gel fracture testing under compression examines the behavior of the filling material under mechanical load, while gel filling properties such as cohesion and stability are evaluated. Furthermore, individual testing programs can be developed for each implant according to customer-specific requirements. This allows specific needs to be addressed precisely and further enhances the safety and performance of medical products.
Failure Analysis of Implants
In addition to mechanical and standard-based testing, INNOPROOF also offers comprehensive failure analysis for implants. Damaged or failed implants are systematically examined to identify the root cause of failure. The objective is to distinguish between material-related, design-related, manufacturing-related, or application-related causes.
The analyses include macroscopic and microscopic examinations as well as material and mechanical evaluations. Based on these investigations, failure mechanisms can be understood and targeted improvements can be derived for future product generations. Failure analysis therefore makes a significant contribution to quality assurance and the further development of implant systems.
What Role Do Standards Play in Implant Testing?
For manufacturers, standards are an essential part of the regulatory approval process, as they support the requirements of authorities such as the FDA and the EU MDR. At the same time, they reduce risks by defining established test methods for different implant types and helping to identify potential weaknesses at an early stage.
Despite their importance, standards do not always cover all specific design features of modern implants. Therefore, they are often supplemented by customized testing concepts to evaluate product-specific characteristics under realistic conditions. Standards provide the foundation, while tailored testing methods serve as the necessary complement for innovative medical technology.
At INNOPROOF, we follow a clearly structured and fully traceable process for the testing of medical implants. The objective is to generate reproducible results that meet regulatory requirements while reliably supporting product development.
High-Precision Testing Technology for Demanding Implant Testing
