Blood Vessel Configurations are perfect castings of the inner blood vessels, body parts and whole bodies. A revolutionary technological process, consisting of injection, curing and removal of remaining tissue, enables us to produce specimens that demonstrate precisely even the smallest and filigree blood vessels. They are three-dimensional and illustrate the complex work of blood vessels in the human body or body parts. Blood Vessel Configurations have a high didactic value and allow students and professionals to examine structures and details of the blood vessels better than any model. They illustrate body cavities, vascular systems, the course of blood vessels and bifurcation patterns within an organ or body system.
