Compositions, methods and apparatus for inhibiting fogging of endoscope lenses |
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.
