L'implantologie cardiovasculaire avec effraction tissulaire minimale : de nouveaux défis pour les biomatériaux

The outstanding development of minimally invasive techniques to cure cardiovascular pathologies brings many challenges as for the design, the deployment and the durability of the devices. The difficulties met with the prostheses in open-surgery seem to be amplificated. Solutions have to be found because of the infatuation of the medical community for minimally invasive techniques that goes along with more demanding requirements. Considering the increasing life expectancy of the population and the requirements of pediatric surgery, numerous validated and innovative implants must be available without any delay. The expectations of the medical community are skyscraping. Any failure related to a prosthesis is no longer tolerated and must be prevented. In this context, the 3Bs rule i.e.biocompatibility, biofunctionnality and biodurability must be highlighted. Any failure is always financially expensive but it can also be morally inacceptable as well.
