  • Bone regeneration membrane and method for forming a bone regeneration membrane
    Patent number: 9724144
    Abstract: A bone regeneration membrane comprising: a dense layer made of resorbable polymer, said dense layer having first and second opposite surfaces and being adapted to form a barrier to cells and soft tissues, a nanofibrillar layer made of resorbable polymer and attached to the first surface of the dense layer, said nanofibrillar layer comprising fibers having a diameter of nanometer size, said fibers being interlaced so as to present an average pore size greater than 10 ?m to allow cell permeability and bone tissue regeneration, the nanofibrillar layer having a permeability ? between 0.4*10-9 m2 and 11*10-9 m2, preferably between 1*10-9 m2 and 4*10-9 m2, in particular substantially of 2*10-9 m2.
    Type: Grant
