Abstract: An additive manufacturing system may include a heating cartridge defining an interior volume and at least one filament port. The system may include a heating element thermally coupled to the heating cartridge to heat the interior volume. The system may also include a filament handling system to feed at least one filament through the at least one filament port. The system may include a substrate handling system having at least a head stock. The system may include a controller configured to initiate or control movement of a substrate relative to the heating cartridge to apply a jacket to the substrate.

Abstract: A distal electrode of an electrode assembly, for example, employed by an implantable medical electrical lead device, extends distally from a distal terminal end of a sleeve of the assembly; and the sleeve, which defines a longitudinal axis of the assembly, includes a plurality of channels that provide fluid communication between a steroid eluting component, which is seated in an external groove of the sleeve, and an area distal to the distal terminal end of the sleeve. Floors of some or all of the sleeve channels may angle toward the longitudinal axis of the assembly, being closer to the axis at the distal terminal end of the sleeve. The assembly may further include a proximal electrode secured to a proximal end of the sleeve, wherein the proximal electrode may be mounted around an outer surface of the sleeve or coupled to the sleeve by means of a coupling component.

Abstract: An additive manufacturing system for producing a medical catheter or lead and a method thereof. The system including a heating cartridge defining an interior volume and at least one filament port. The system also including a heating element thermally coupled to the heating cartridge to heat the interior volume, a filament handling system to feed at least one filament through the at least one filament port, and a substrate handling system. The substrate handling system including a clamp to secure a portion of a substrate to be moved relative to the heating cartridge to apply a jacket to the substrate. In one or more embodiments, a subassembly is positioned on the substrate and has an electrode ring. The jacket printed to cover at least a portion of the subassembly and spaced apart from the electrode ring.
