Abstract:
1. A method for manufacturing a tubing for connecting components in medical devices, the method comprising: transfer or injection molding an inner layer around a core to define an inner surface adjacent to the core and an outer surface opposite the inner surface using inner layer cavity mold halves, said outer surface including one or more recessed pathways defined therein; forming a reinforcement member in each of the one or more recessed pathways of the molded inner layer; transfer or injection molding an outer layer including an inner surface and an outer surface over the inner layer and the reinforcement member using outer layer cavity mold halves, wherein the inner surface of the outer layer substantially conforms to the outer surface of the inner layer and the reinforcement member, at least one of the inner layer cavity mold halves and the outer layer cavity mold halves including a sprue and a runner for transferring an elastomer to ring gate halves on an end of the tubing that introduces the elastomer into a mold cavity; removing the outer layer, inner layer, and reinforcement member from the outer layer mold cavity halves; and removing the core from within the inner layer to provide a lumen through the inner layer.
