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.

Interventional medical device with balloon-actuated cover

Implantable apparatus includes two or more alignable marker elements, and systems and methods for manufacturing such implantable apparatus, and methods to utilize such implantable apparatus. For example, the implantable apparatus may include a first alignable marker element and a second alignable marker element that may be used to ensure proper alignment with a target site.

Lead construction including alignable marker elements

Medical devices that provide for selected curve deflection in multiple planes such that three-dimensional shapes can be formed in the medical devices by placing a pull wire extending through the catheter in tension, as well as methods of manufacturing and using the medical devices. The medical devices may include selected portions in which the location of the pull wire changes circumferentially and/or radially to provide for the selected curve deflection. The medical devices may include, in addition to, or in place of changes in pull wire location, selected portions having exhibiting changes in rigidity to provide for the selected curve deflection.

Medical devices with multi-plane articulation

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.

3D printed medical devices including internal shaping

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.

Filament wrapping and reflow system and methods to manufacture an elongate medical device

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.

Systems and methods for manufacturing 3D printed medical devices

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.
