A manufacturing process forms a bored hollow lumen. The manufacturing process includes providing a solid rod of a bioresorbable material and boring a hole axially through the solid rod. The manufacturing process also includes modifying surface defects formed on a luminal surface by the boring, the luminal surface defining the hole, thereby forming the bored hollow lumen. A bored hollow lumen includes a lumen wall including a bioresorbable material. The lumen wall has an abluminal surface and a luminal surface. The luminal surface defines a bore through the bored hollow lumen. The bioresorbable material has a uniform crosslinking density.

A porous biocomposite material including a polymer matrix having pores defined by several surfaces and collagen on the surface of the pores and the outer surfaces of the polymer matrix, the ratio, by weight, collagen to polymer matrix is from 20:80 to 40:60. The polymer matrix of the porous biocomposite material includes a copolymer which is prepared from a poly(ε-caprolactone) diol, a poly(lactide-co-glycolide) diol and a lysine diisocyanate (LDI). Also included are an implant which is a biodegradable, porous foam and with similar biomechanics to the normal meniscus, with tensile, compressive and tear strength, and preventing the pores from collapsing under condyle-tibia pressure. It serves as a scaffold for damaged meniscus repair or replacement, indicated for grade 3 or 4 terminal knee arthrosis, for the prevention of treatment, by cartilage regeneration, of advanced knee arthrosis, to avoid knee prostheses in young patients.

The disclosure relates to compositions comprising crosslinked hyaluronic acid physically mixed with collagen. Also contemplated are methods of improving an aesthetic quality of an anatomic feature of a human being.

A bioscaffold comprising a graphene matrix for use in cellular therapy is disclosed. In particular, a bioscaffold having a coating of dexamethasone on a three-dimensional graphene matrix is provided, wherein the bioscaffold elutes dexamethasone to reduce inflammatory responses following implantation of the bioscaffold in a subject. Having the dexamethasone released locally in the vicinity of the bioscaffold avoids the systemic side effects from conventional intravenous delivery while allowing the dexamethasone to modulate the inflammatory milieu within the transplantation microenvironment.
