  • Intravascular lithotripsy systems and methods
    Patent number: 11957369
    Abstract: Various embodiments of the systems, methods and devices are provided for breaking up calcified lesions in an anatomical conduit. More specifically, an electrical arc is generated between two spaced-apart electrodes disposed within a fluid-filled balloon, creating a subsonic pressure wave. In some embodiments, the electrodes comprise a plurality of points or extensions that allow the electrical arc to form at any one of the plurality of points to, among other things, extend the electrode life.

  • High-resolution rapid manufacturing
    Publication number: 20070229497
    Abstract: The present invention is a method for forming an object, the method comprising jetting a first material to form a plurality of layers that define a support structure increment, and extruding a second material to form a layer of the object. The layer of the object substantially conforms to an interior surface of the support structure increment.

  • High-precision modeling filament
    Publication number: 20050129941
    Abstract: Disclosed is a modeling filament for use as feedstock in a fused deposition modeling liquifier, and a method for manufacturing the filament. The diameter and standard deviation of the filament are controlled to meet various tolerance requirements of jam resistance, slip resistance, model strength, liquifier overflow prevention and hysteresis-free transient response. Standard deviation of the filament diameter is matched to a filament target diameter. The resulting filament is used to form high-quality models.
