摘要： Methods for preventing and/or eliminating fogging of endoscope lenses during an endoscopic procedure which include the steps of introducing an endoscope into a body cavity and contacting the endoscope lens with a biocompatible and biodegradable composition containing a polyalkylene oxide while the lens is positioned within the body. Alternatively, the endoscope may be coated with a biocompatible polyHEMA coating which is activated by a biocompatible solution, such as water or saline, which may be introduced during use through a fluid conduit on the endoscope. Devices for preventing and/or eliminating fogging of endoscope lenses during endoscopic procedures and conveying antifogging solutions to the distal end of the endoscope are also provided, and may include a distensible applicator.

摘要： Surgical adhesion barriers and methods of using such surgical adhesion barriers are provided. Surgical adhesion barriers according to the present invention have at least one layer of a bioabsorbable material comprising copolymers and/or block copolymers derived from trimethylene carbonate. Alternatively, a multilayer surgical structure having one or more bioabsorbable layers superimposed on a non-absorbable layer is useful for minimizing or preventing formation of fibrous adhesions between a healing trauma site and adjacent surrounding tissue. Alternatively, a bioabsorbable non-woven fabric in adherent contact with at least one bioabsorbable layer of foam, film, mesh, web or woven fabric is also provided. One or more medicinal agents may be interposed between or disposed within any of the aforementioned layers.

摘要： A gut suture is coated with a bioabsorbable copolymer obtained by polymerizing a major amount of .epsilon.-caprolactone and a minor amount of at least one other copolymerizable monomer in the presence of polyhydric alcohol as initiator. The coated gut suture can be packaged in the absence of conventional tubing fluid, i.e., in the dry state, while at the same time retaining flexibility, pliability and resistance to fray. In an alternative embodiment, a gut suture is coated with a pre-coating composition prior to being coated with the bioabsorbable copolymer.
