  • Patent number: 8753659
    Abstract: An intravascular stent has a coating comprising a crosslinked amphiphilic polymer and a sparingly water soluble matrix metalloproteinase inhibitor (MMPI). Preferably the polymer is formed from 2-methacryloyloxy-2?-ethyltrimethylammonium phosphate inner salt, C4-18 alkyl methacrylate and reactive and/or crosslinking monomer and the MMPI is a hydroxamic acid, more preferably batimastat. Preclinical and clinical results are reported, showing good luminal areas and reduced intimal thickening.
    Type: Grant
    Filed: May 20, 2013
    Date of Patent: June 17, 2014
    Assignee: Abbott Laboratories
    Inventors: Andrew L. Lewis, Peter W. Stratford, Michael J. Driver
  • Patent number: 8512733
    Abstract: It is provided an intravascular stent comprising a metal body and a coating comprising a polymer and a restenosis inhibiting agent in which the restenosis inhibiting agent is a sparingly water soluble drug and the polymer in the coating is a cross-linked amphiphilic polymer, wherein the amphiphilic polymer comprises groups conferring hydrophobicity and groups conferring hydrophilicity.

  • Patent number: 6758839
    Abstract: A tampon for feminine hygiene or medical purposes comprising a nonwoven cover having at least one, outwardly directed, smooth surface and substantially enclosing a liquid absorbing core wherein the nonwoven cover comprises at least partly thermoplastic, heat-sealable fibers and pressed to the final shape of the tampon. Before the tampon blank is covered with the nonwoven covering web, said web was subject to the use of heat and pressure during the manufacturing of the tampon as to smooth out at least the outer surface of the nonwoven covering web, whilst maintaining the structure of the nonwoven covering web and the absorbency of the tampon. Thereby, it is achieved that the tampon can also be more easily and more comfortably introduced into and withdrawn from a body cavity before and after the days of stronger menstruation or at the occurance of only less vaginal exudation as garment protection.
