    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: The present invention discloses novel crosslinked biomaterial compositions which are prepared using hydrophobic polymers as a crosslinking agent. Preferred hydrophobic polymers are those that contain two or more reactive succinimidyl groups, including disuccinimidyl suberate, bis(sulfosuccinimidyl)suberate, and dithiobis(succinimidyl)propionate. Crosslinked biomaterial compositions prepared using mixtures of hydrophobic and hydrophilic crosslinking agents are also disclosed. The compositions of the present invention can be used to prepare formed implants for use in a variety of medical applications.
