Abstract: Systems and methods for manufacturing elongate medical devices including internal components embedded between multiple jacket layers. The system including a heating cartridge, a heating element, a filament handling system, a substrate handling system, and a controller to feed and melt each of the filaments for forming the multiple jacket layers. The system may include a single heating cartridge adapted to make multiple passes to form a first and second jacket or multiple heating cartridges that sequentially form a first and second jacket.

Abstract: Systems and methods of manufacturing 3D printed medical devices. The method includes feeding a first filament and a second filament into an interior cavity of a heating cartridge and melting each of the filaments on a substrate. The heating cartridge is then moved linearly and rotationally relative to the substrate to form a jacket including material from each of the first and second filaments. Further, rotating the substrate provides a uniform mixture and creates support rings between the filament materials within the structure of the jacket.

Abstract: Systems and methods for manufacturing an elongate medical device including various surface features. The system including a heating cartridge, a heating element, a filament handling system, a substrate handling system, a controller, and one or more additional components adapted to form the surface features on the medical device. The heating element melts a filament material within the heating cartridge to form a jacket of the medical device and the one or more additional components engages the outer surface of the jacket to create surface features.
