  • Patent number: 7776081
    Abstract: The invention relates to medical devices, in particular condoms/drains, that find use in anastomosis. Thus the present invention relates to these medical devices per se, to a medical kit comprising these medical devices, to the use of these medical devices, to a method for medical treatment involving application of these medical devices to an organism who is in need thereof as well as to the use of certain biocompatible, biodegradable synthetic polymers in the preparation of a medical device for the treatment of a disease or a condition which requires anastomosis. The medical devices of the present invention are typically condom shaped and are used for the protection of anastomosis. The devices comprise a tubular shaped part which is made of a biocompatible, biodegradable polymer. The devices may be applied by stapling.

  • Publication number: 20060142736
    Abstract: The invention relates, generally, to medical appliances. More particularly, it relates to tubular shaped devices used as drains for draining fluids (liquids and/or gases) from antrums or other parts of the human or animal body. According to the present invention a drain is provided, which is suitable for draining a human or animal antrum, which drain comprises a synthetic biodegradable material, preferably a biodegradable polymer.

  • Publication number: 20060008419
    Abstract: The invention relates, generally, to porous absorbent materials which are suitable for packing antrums or other cavities of the human or animal body. More particularly, it relates to hydrophilic biodegradable foams, which may be used, e.g., in the form of a plug or tampon, for instance for controlling bleeding, wound closure, prevent tissue adhesion and/or support tissue regeneration. The invention provides an absorbent foam, suitable for packing antrums or other cavities of the human or animal body, comprising a biodegradable synthetic polymer, which polymer comprises —C(O)—O— groups in the backbone of the polymer, for instance polyurethane and/or polyester units combined with polyethers.
