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 attachment device for securing a medical device to a patient, comprising at least one layer including a flexible portion and a rigid portion. The rigid portion being connected to the flexible portion and defining at least one loop. The at least one loop including an elongate body and an anchoring element. The elongate body having a first end and a second end opposite the first end. The anchoring element being disposed circumferentially around, and connected to, the elongate body.

Abstract: Aspects of this disclosure relate to a welding system that is configured to execute opposed, step, and parallel gap resistance spot welds (RSW) and associated methods. The system may be configured to switch bases to switch between an opposed weld configuration, a step weld configuration, and a parallel gap configuration. The system may include an accelerometer that is secured to the weld head adjacent one of the electrodes. The system may use the accelerometer to determine whether or not an RSW was defective. Acceleration data may indicate a defective weld when it includes acceleration data that is outside of a threshold range of acceptable acceleration data.

Abstract: A medical electrical lead may include a conductive electrode shaft located near the distal end within the lead body, a coiled conductor extending within the lead body from the proximal end and coupled to a first end of the conductive electrode shaft, and an electrode located near the distal end of the lead body and coupled to an opposite end of the conductive electrode shaft as the coiled conductor. The lead may also include an energy dissipating structure located near the distal end of the lead body and defining a lumen through which a portion of the coiled conductor extends. The energy dissipating structure may include a region having one or more protrusions extending toward a central axis of the lumen to push the coiled conductor off center relative to the central axis of the lumen.

Abstract: A medical electrical lead includes a conductive component coupling a coil to a wire or cable; the conductive component includes a first side, a second side, a first groove formed in the first side and a second groove formed in the second side. The first groove holds a portion of the cable and the second groove holds a portion of the coil.

Abstract: A medical device shaft includes a first longitudinal edge joined to all or a portion of a second longitudinal edge, and an inner surface forming a plurality of lumens separated by a plurality of longitudinal ribs extending along a length of the shaft; wherein a base of each rib is spaced apart from one another and each rib is joined to one another in proximity to a peak of each rib. Each of a plurality of elongated members extends within one of the plurality of lumens of the shaft.
