摘要: This invention relates to a graft for use in reconstructive surgery repair damaged tissue, such as bone cartilage vascular tissue or nerve tissue. According the is characterized by porous matrix of an organic polymeric material having bi-porous structure, i.e., at least two different pore structures each its own size and distribution. The preferably biodegradable incorporates fibrous and/or granular material, also biodegradable, additives, growth factors. process making grafts.
