The changing regulatory landscape for biomedical implants and its relationship to withdrawal of some vaginal mesh products.

Abstract

Advancements in biomedical engineering and advanced therapies including tissue engineering products necessitate revisions to the regulation and governance of their production and use to ensure patient safety. In this review, the current regulations and recent improvements on the governance of biomedical devices are reviewed. Current regulations on approval of biomedical devices failed to address some important aspects related to the definition of biocompatibility of medical implants. The main issue was that the failure to establish design requirements for a specific application - in this case, the pelvic floor. Another issue was the lack of knowledge on disease mechanisms leading to an inability to define clear targets for surgical treatment. A clear example of this is the recent vaginal mesh scandal. Surgical innovations are inherently challenging. It is no surprise that the regulatory landscape lags behind advancements in biomedical technologies. Very recent modifications to the available regulations particularly in Europe aim to establish a robust, transparent, predictable and sustainable regulatory framework for medical devices, which ensures patient safety while supporting innovation.
