A process for making a polymeric composition to prevent or inhibit the formation of tissue adhesions or to inhibit bleeding.

摘要

"fragmented polymeric composition, processes for making it, sealing a tissue tract, inhibiting bleeding at a target site in a patient's body, releasing an swellable composition to a target site in the tissue, and applying a polymeric composition to a target site in the patient. a patient's body, set of utensils, applicator containing a molecular cross-linked hydrogel, and sterile packaging. " Cross-linked molecular gels comprise a variety of biological and non-biological polymers, such as proteins, polysaccharides and synthetic polymers. Such molecular gels may be applied to target sites on a patient's body by extruding the gel through a hole in the target site. alternatively, the gels may be mechanically fragmented and used in implantable articles such as breast implants. When used in vivo, the compositions are useful for inhibiting spinal and other postoperative tissue adhesions, for filling tissue pieces, tissue treatments, body cavities, surgical defects, and the like.
