  • Artificial meniscus
    Patent number: 11147677
    Abstract: An artificial meniscus using a thermoplastic for the base material, which is reinforced with an inert material. In a preferred embodiment, the reinforcement is provided by Kevlar® fibers, and the matrix is made out of polycarbonate-urethane (PCU). In an alternate embodiment, the PCU can also be surrounded by a polycaprolactone (PCL) scaffold that is infused with human growth proteins so that when the artificial meniscus is implanted, stem cells in the body are stimulated to ensure the meniscus is properly secured.
