  • Patent number: 12311125
    Abstract: 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.

  • Publication number: 20240226511
    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.

  • Publication number: 20240123197
    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.

  • Publication number: 20240009925
    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.
