  • Patent number: 8833434
    Abstract: A method for making hollow metal tubes includes a step combining a polyphenylene sulfide-containing resin with a water soluble carrier resin to form a resinous mixture. The resinous mixture is then extruded to form an extruded resinous mixture. The extruded resinous mixture includes polyphenylene sulfide-containing fibers within the carrier resin. The extruded resinous mixture is contacted (i.e., washed) with water to separate the polyphenylene sulfide-containing fibers from the carrier resin. The polyphenylene sulfide-containing fibers are then coated with a metal layer. The hollow metal tubes are then formed by removing the polyphenylene sulfide-containing fibers.

  • Publication number: 20140213696
    Abstract: Embodiments of the invention provide a method of processing natural rubber latex using an extruder including a plurality of process zones by processing coagulant with latex to produce a coagulum and serum. In some embodiments, the coagulant can include an acid, a metal salt, or a mixture of both. Some embodiments can include a coagulum wash stage, and a deresination step. In some embodiments, the extruder can be operated to move coagulum through the extruder to remove at least some fraction of water to form a substantially dewatered coagulum, and a drying step to form a dried coagulum. In some embodiments, a stabilizer such as an antioxidant can be introduced into the extruder, and processed to remain in some fraction in the dried coagulum. Some alternative embodiments include a latex processing method of providing a flow of coagulant, and combining latex with the flowing using an emulsion dispensing bar.

  • Patent number: 8632846
    Abstract: Methods and apparatus are disclosed for loading a therapeutic substance or drug within a lumenal space of a hollow wire having a plurality of side openings along a length thereof that forms a hollow drug-eluting stent with a plurality of side drug delivery openings. Loading a drug within the lumenal space of the hollow stent includes a drug filling step, in which the drug is mixed with a solvent or dispersion medium. The lumenal space may be filled with the drug solution or suspension in a reverse fill process and/or a forward fill process. After the drug filling step, a solvent or dispersion medium extracting step is performed to extract the solvent or dispersion medium from within the lumenal space such that only the drug remains within the hollow stent. A stent cleaning step may be performed to an exterior surface of the hollow stent.
