    摘要: Anti-adhesion films useful for the prevention of surgical adhesions are disclosed. These films comprise substrate materials (such as collagen) and hetero-bifunctional anti-adhesion binding agents, wherein the substrate material is covalently linked to receptive tissue within the body of a patient via the binding agent. Preferred binding agents comprise substrate-reactive and tissue-selective functional groups. Anti-adhesion compositions useful for the formation of such films are also disclosed.

    摘要: Medical devices, and more particularly, devices, methods and compositions for sealing tissue puncture openings of patients after surgical operations are provided. A puncture wound sealing apparatus includes a positioning device having a depth sensing mechanism capable of providing feedback to an operator for the precise placement of an implant that is preferably resorbable and swellable after implantation. Such an implant provides for efficient sealing of the tissue puncture opening thus avoiding complications after surgical procedures in which blood vessels are punctured.
