HYBRID HETEROGENEOUS HYDROGEL, MANUFACTURING METHOD AND USE AS AN IN-SITU NON-DEGRADABLE FILLER IMPLANT
A filler implant includes a support of hybrid heterogeneous hydrogel which is formed by a copolymer including: a dendrimer monomer which is functionalised by an ethylene radical, an acryl amide compound which is selected from an N-substituted methacrylamide and N-substituted acrylamide, a cross-linking agent and a bioactive copolymerisable material. The support is formed by microbeads which have a diameter between 1.5 micrometres and 10 micrometres and it predominantly contains by weight the acrylamide compound. The microbeads are assembled to form aggregates which contain between 5 and 50 microbeads. The aggregates are connected by cross-linking points in order to define a penetrating porous network which defines three-dimensional percolating paths. The penetrating porous network is formed by pores, the majority of the volume of which has a diameter between 10 and 30 micrometres. The support has a viscoelastic nature with a modulus of elasticity between 1 and 200 kPa.
