    摘要: Biodegradable, flowable or flexible polymer compositions are described comprising a polymer having the recurring monomeric units shown in formula I: 1 wherein: each of R and Rnull is independently straight or branched alkylene, either unsubstituted or substituted with one or more non-interfering substituents; L is a divalent cycloaliphatic group; Rnull is selected from the group consisting of H, alkyl, alkoxy, aryl, aryloxy, heterocyclic or heterocycloxy; and n is 5 to 1,000, wherein said biodegradable polymer is biocompatible before and upon biodegradation. In one embodiment, one or more of R, Rnull or Rnull is a biologically active substance. Amorphous compositions containing a biologically active substance, in addition to the polymer, and methods for controllably releasing biologically active substances using the compositions, are also described.

    摘要: The present invention provides medical devices such as medication infusion pumps having internal surfaces that are treated to inhibit protein denaturation. In accordance with the invention, hydrophilic internal surfaces and related coating methods are provided to reduce or eliminate accumulation of medication deposits which can otherwise occur when handling complex protein-based medications. Preferred hydrophilic pump surfaces include hydrophilic surfactants (PEO) or (PEG) coatings which exhibit very low protein adsorption characteristics. Several methods are disclosed for producing such treated surfaces including the covalent attachment of hydrophilic surfactants.

    摘要: The present invention relates to a collagen material comprising a laminate in which a collagen ultra-fine fibrous non-woven fabric-like multi-layer structure is sandwiched between non-fibrous collagen layers, a thread-like material containing said collagen material, their production processes, and a medical material containing said collagen material, and particularly a medical alternative membrane comprised of said medical material. These use collagen for their raw material without combining the use of a synthetic polymer material, possess physical properties to an extent that allows suturing while still maintaining the biochemical properties inherently possessed by collagen, and the alternative medical membrane can be used as a material for filling in the missing portions of biomembranes such as endocranium, pericardium, pleura, peritonium or serous membrane, presents no ethical problems, is in stable supply, has no risk of infection, does not cause cell degeneration, allows control of the rate of degradation following application to the body, and has an action that promotes regeneration of biomembranes.
