  • Patent number: 7025990
    Abstract: Methods are provided for forming hydrogel barriers in situ that adhere to tissue and prevent the formation of post-surgical adhesions or deliver drugs or other therapeutic agents to a body cavity. The hydrogels are crosslinked, resorb or degrade over a period of time, and may be formed by free radical polymerization initiated by a redox system or thermal initiation, or electrophilic-neutrophilic mechanism, wherein two components of an initiating system are simultaneously or sequentially poured into a body cavity to obtain widespread dispersal and coating of all or most visceral organs within that cavity prior to gelation and polymerization of the regional barrier. The hydrogel materials are selected to have a low stress at break in tension or torsion, and so as to have a close to equilibrium hydration level when formed.

  • Patent number: 6784282
    Abstract: A method for modifying the surface properties of tissue in vivo is described. The method comprises forming a liquid crystalline matrix on the tissue surface wherein the matrix comprises a tissue surface component. In one embodiment there is provided a method for improving the bonding of surgical glues and cements to cartilage and other synovial fluid wetted tissue surfaces. Such surfaces are contacted with a composition comprising a poly(hydroxy substituted amino acid) to form a liquid crystalline matrix on the tissue surface. The matrix is readily removed to provide a tissue surface that exhibits improved bonding with surgical glues.
