Method of formation of artificial organ components using a plastic dispenser system manipulated by a robot

In order to produce an artificial organ component having a complicated structure, a plastic-forming method was proposed in which small amounts of material were accumulated successively by using a dispenser system manipulated by a robot; a preliminary experiment with silicone rubber was conducted. Components of different shapes were produced, including straight tubes, tapered tubes, bifurcating tubes, tubes having leaflets on the inside, cones, spiral tubes, and tubes with a sack. This method provides the possibility of producing complicated artificial organ components, which are difficult to produce by conventional plastic-processing methods.
