Abstract: A medical lead system including an elongated lead body configured to extend through vasculature of a patient. The lead body mechanically supports a fixation member extending distal to a distal end of the lead body. A balloon is affixed to a distal portion of the lead body. The balloon is configured to inflate to extend distal to the distal end of the lead body. The fixation member is configured to extend within a distal cavity defined by the inflated balloon. The medical lead system is configured such that an electrode mechanically supported by the fixation member may electrically communicate with tissue of the patient when the balloon is in the inflated configuration.

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: Devices, systems, and methods for treating vessel openings are disclosed herein. According to some embodiments, a device for treating a vessel opening comprises a housing configured to be positioned within an opening in subcutaneous tissue proximate the vessel opening. The housing can comprise an inner wall and an outer wall. The inner wall can define a first lumen configured to receive an elongate member therein and the inner and outer walls can define a second lumen configured to receive an adhesive. The outer wall of the housing can define one or more apertures extending radially from the second lumen to an environment external of the housing. The device can comprise an actuator configured to be received within the second lumen. Movement of the actuator can force the adhesive to move through the aperture to the external environment and into an extravascular space within the subcutaneous tissue proximate the vessel opening.

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: Medical devices including a balloon and methods of making medical devices including a balloon are provided. The medical device includes a tubular element, a balloon, and a barrier between the tubular element and the balloon. When air is pushed into one end of the medical device, the balloon may be inflated. The method includes applying a barrier to a tubular element, applying an elastomer solution to the barrier and at least a part of the tubular element to form a coating, and curing the coating to form the balloon.
