  • Patent number: 11643754
    Abstract: A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a matrix of a first base polymer and particles dispersed within the matrix, and a shell portion comprising a same or a different base polymer. The consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional part, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament and retain the particles within the roads of the printed part and do not penetrate the outer surface of the shell portion.
    Type: Grant

  • Patent number: 10456565
    Abstract: A drainage catheter system includes an elongate tube with proximal and distal ends and a filament extending the tube that is adjustable to create a closed loop at the distal end of the tube when the filament is retracted relative to the tube. The filament is coupled to the tube such that the filament and tube are prevented from being separated in the event that the tube and filament are cut at the proximal end at the conclusion of a drainage procedure. The filament can be attached to the tube near the distal end. The filament can be attached to the tube along its length. The catheter system can also include a retraction mechanism having a first fixed position and second fixed position, where the second fixed position retracts the filament proximally relative to the first fixed position by actuating a plunger.
