Abstract:
1. A three-dimensional biocompatible scaffold comprising a first and a second biocompatible material, said first material shaped as one or more grids of micron sized strands forming an open network of voids, said second material filling the voids of said open network, said second material being porous, wherein the pores are interconnected, said second material having a plurality of open cells substantially uniformly distributed therein, wherein the average size of said open cells is 1 nm to 6 micrometer, said grid providing protective mechanical support of the second biocompatible material, said grid further protecting the three-dimensional biocompatible scaffold against compressive forces during preparation, insertion and use, and said second biocompatible material comprising one or more biocompatible polymers, wherein the initial compressive stiffness of the grid is 5-100000 times higher than the initial compressive stiffness of the second biocompatible material.
