The subject invention is directed to devices and methods for producing devices for regulating blood flow in the venous system. In particular, the invention provides for artificial valves designed to regulate the flow of blood in human vessels, wherein such artificial valves include superior properties including fatigue resistance, biocompatibility, and ease of manufacture.

Composite materials are made by impregnating a non-conductive material with a conducting monomer to form a monomer-impregnated non-conductive material, and polymerizing the monomer-impregnated non-conductive material to form the composite material. The composite materials are used in medical devices and implants.

A solidifying prepolymeric implant composition comprising a biocompatible prepolymer and an optional filler. One such implant composition is a polyurethane implant composition comprising an isocyanate, such as hydroxymetbylenediisocyanate (HMDI) and an alcohol, such as polycaprolactonediol (PCL diol). The compositions of the invention are useful for improving bone structure in patients by applying the solidifying implant composition to bone, reinforcing bone structure, improving load bearing capacity and/or aiding healing of microfractures.

Absorbable implants can be used to create volume and shape in soft tissues with regenerated tissue. The implants comprise lattices formed from multiple unit cells. Unit cells can be coils or springs, skeletal polyhedrons, foams, or structures derived from mesh and fiber. The implants may be coated or filled with cells and tissues, and preferably with autologous fat graft. The implants are particularly suitable for use in plastic surgery procedures, for example, to regenerate or augment breast tissue following mastectomy or in mastopexy procedures, and can provide an alternative to the use of permanent breast implants in these procedures.
