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.

Abstract: An implantable medical lead includes a lead body, an electrode, a lead electrical connector, and a rotational electrical coupling. The lead electrical connector is configured to establish electrical communication between a test device and the electrode. The rotational electrical coupling includes a first conductive component electrically connected to the electrode and a second conductive component electrically connected to the first conductive component. The second conductive component is configured to establish electrical communication with the test device. The rotational electrical coupling is configured to facilitate rotation of the first conductive component relative to the second conductive component.
