  • Patent number: 11389257
    Abstract: Medical device kits for use in placing, maintaining, altering, and/or removing medical devices in, on, and/or from the body of a patient are disclosed. Such medical device kits can include one or more wrap assemblies for use in the placement/maintenance procedure. In accordance with present embodiments, the one or more wrap assemblies of the medical device kit can include various features to assist the clinician performing the particular procedure. In one embodiment, a medical wrap assembly is disclosed, comprising a foldable wrap body that includes a front surface, wherein the front surface is configured to define a sterile field. A plurality of pockets is included on the front surface of the wrap body. The pockets are configured to contain therein a plurality of medical components. The medical components are arranged in the pockets in a predetermined order of use for the medical procedure.

  • Patent number: 4582859
    Abstract: An improved process for the manufacture of crosslinked copolymer particles from seed particles by imbibing a monomer therein and polymerizing the same under controlled suspension conditions wherein said improvement comprises expanding the seed in staged or sequential steps of feeding lower levels of crosslinking monomers in the early stages and preferably higher levels of crosslinking monomers at later stages of polymerization.

    Date of Patent: April 15, 1986
    Assignee: Rohm and Haas Company
    Inventors: George M. Lein, Jr., Thomas J. Howell, James H. Barrett
  • Patent number: 4431785
    Abstract: Hard, infusible, discrete beads of crosslinked copolymer are prepared by free-radical catalyzed polymerization of a monomer mixture in aqueous dispersion wherein a minor amount of a modifier, specifically an organic compound containing acetylenic or allylic unsaturation having the ability to moderate the rate of polymerization, is incorporated in the monomer mixture. Ion exchange resins having improved mechanical strength are obtained by attaching functional groups to the copolymer.
