Abstract: A filament wrapping and reflow system and a method therefrom. The method including wrapping a filament around an elongate substrate along a longitudinal direction between a proximal end of the elongate substrate and a distal end of the elongate substrate. The method also including melting the filament to form at least a portion of the elongate medical device. The system including a substrate system, a filament system, a heater, one or more actuators, and a controller.

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.

Abstract: Medical devices including a balloon-actuated sheath are provided. The medical devices include a tubular body, a tooltip, a balloon, and a tubular sheath translatably coupled to the balloon. Medical devices including a balloon-actuated distal cap are provided. The medical devices include a tubular body, a tooltip, a balloon, and a distal cap translatably coupled to the balloon. When air is pushed into one end of the medical device, the balloon may inflate, translating the tubular sheath or distal cap along a longitudinal axis from a retracted position to an extended position. When in the extended position, the tubular sheath at least partially surrounds the tooltip. When in the extended position, the distal cap at least partially opens fluid communication between the tooltip and the environment.

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 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.
