发明名称 TWO-SHOT MOLDED OPTICAL OBTURATOR
摘要 A method of manufacturing an optical obturator includes providing an injection mold including a mold cavity defining an outer surface of the optical obturator and a core pin centrally positioned within the mold cavity. The core pin defines an inner surface of the optical obturator. In particular, the core pin may be cantilevered to the injection mold. The method further includes injecting a first material between the core pin and the mold cavity to form the tubular shaft and injecting a second material between a distal portion of the core pin and a distal portion of the mold cavity to form the optical tip.
