  • Publication number: 20250204915
    Abstract: A process for adding compliance to a blood vessel preferably includes forming a first puncture through a first wall segment of the blood vessel, forming a second puncture through a second wall segment of the blood vessel at a diametrically opposed location, deploying a first tissue anchor on an outside of the blood vessel in an area of the first puncture, deploying a second tissue anchor on the outside of the blood vessel in an area of the second puncture, and tensioning an elastic band coupled to the first tissue anchor and the second tissue anchor, thereby causing the elastic band to reshape the target segment of the blood vessel to a non-circular cross-sectional shape. The elastic band elongates and contracts during cardiac cycles for adding compliance to the blood vessel.

  • Patent number: 9975171
    Abstract: Disclosed are systems and methods for mechanically reducing an amount of the skull material in a finished, molded part formed from amorphous alloy using an injection molding system. Skull material of molten amorphous alloy can be captured in a trap before molding such material. A cavity can be provided in the injection molding system to trap the skull material. For example, the cavity can be provided in the mold, the tip of the plunger rod, or in the transfer sleeve. Alternatively, mixing of molten amorphous alloy can be induced so that skull material is reduced before molding. A plunger and/or its tip can be used to induce mixing (e.g., systematic movement of plunger rod, or a shape of its tip). By minimizing the amount of skull material in the finished, molded part, the quality of the part is increased.

  • Patent number: 9955533
    Abstract: An induction shield is configured to substantially reduce emissions emitted from an induction heat source (e.g., coil) during use. The shield is positioned adjacent to a vessel (e.g., in an injection system) having a melting portion configured to receive meltable material to be melted therein and an induction heat source positioned adjacent the vessel configured to melt the meltable material received in the melting portion of the vessel. The shield may include a tube configuration configured to flow liquid therein to absorb heat emitted from the heat source. The tube configuration can comprise a single tube or multiple tubes. The shield can be positioned adjacent the induction source in a helical manner, for example, or at ends of the vessel. The shield can be used during melting of amorphous alloy and for forming a part.

The vessel can have a tubular body configured to substantially surround and receive a plunger tip. Longitudinal slots or gaps extend through the thickness of the body to allow and/or direct eddy currents into the vessel during application of an RF induction field from the coil. The body also includes temperature regulating lines configured to flow a liquid within. The temperature regulating lines can be provided to run longitudinally within the wall(s) of the body between its inner bore and outer surface(s). A flange may be provided at one end of the body to secure the body within an injection molding apparatus.

  • Patent number: 9604279
    Abstract: Disclosed is a vessel for melting meltable material having a body with a melting portion configured to receive meltable material to be melted therein and an injection path for injecting the meltable material in molten form after melting (e.g., into a mold). The body has a recess configured to contain the meltable material within the vessel during melting of the material. The vessel is configured for movement between in a first position to restrict entry of molten material into an injection path of the vessel and to contain the material in the recess during melting, and a second position to allow movement of the material in a molten form through the injection path and into the mold (e.g., using a plunger). The vessel can be used in an injection molding system for molding bulk amorphous alloys.

  • Publication number: 20150107730
    Abstract: Embodiments herein relate to a process for semi-continuous or continuous production of a solid object from a molten metal, with the potential of being a cleaner and less expensive alternative to complicated split mold processes currently used. The embodiments can be used to perform multiple melt/pour cycles without breaking vacuum, with the system only opened to remove the solid object via an air lock, e.g., a separate chamber or load lock, which will be periodically opened to remove feedstock without breaking the vacuum of the process chamber. Embodiments also relate to an apparatus for semi-continuous or continuous production of a solid object from a molten metal.
