A surgical system that includes a flowable, curable biopolymer and a porous, implantable anchor biomaterial, the anchor material being adapted (e.g., in terms of porosity and chemical compatibility) to permit the flowable biopolymer to infiltrate some or all of the material's pores and there cure in order to retain and anchor the resultant composite material. The composite material can be adapted to encourage new bone ingrowth, in order to stabilize the retention of the implant over extended use. In one embodiment the biopolymer comprises the components of a polyurethane and the porous anchor material comprises a reticulated open cell carbon foam infiltrated with tantalum by a process of chemical vapor deposition (CVD). |
