  • Drug-eluting catheter and method of manufacturing the same
    Patent number: 9186439
    Abstract: Biocompatible nanoparticles 1 which entrap a bioactive substance and whose surface is positive-charge-modified are electrically adhered to a balloon portion 9 of a catheter main body 5 through a negatively charged resin layer 11, and thus a nanoparticle layer 12 is formed. After the catheter main body 5 is indwell in vivo, the nanoparticles 1 are gradually eluted from the nanoparticle layer 12 and are effectively delivered to cells.
    Type: Grant

  • Filtering apparatus with a pleated filtering element embedded in a filling material
    Patent number: 5618425
    Abstract: A filtering apparatus comprises a housing having a blood inlet and a blood outlet as well as a vent which are formed protrudingly from the housing. A filtering element is provided inside the housing to partition the inside of the housing into a first space and a second space. The filtering element is made from a porous material folded to have a plurality of pleats, the pleated material being arranged to form a hollow truncated cone with the pleats radiating outward. The opening at the top portion of the filtering element is sealed with a filling material. The filling material has a bottom surface that includes a central portion which protrudes into the second space, and this allows a pleat intersecting portion at the outer circumference of the bottom surface to have an inclined surface with respect to the horizontal.
