    摘要： Methods and devices are provided for performing translumenal (e.g., transoral and transanal) procedures. In general, the methods and devices utilize a trocar assembly or trocar end cap that can facilitate insertion of an endoscope through tissue. In one embodiment, a flexible trocar assembly is provided and includes an obturator having an inner lumen formed therethrough for receiving an endoscope therein, and a distal end that is adapted to facilitate insertion of the endoscope through tissue and that is adapted to facilitate viewing therethrough. The trocar assembly can also include a trocar sleeve that is disposable over the obturator. In use, once the trocar assembly is inserted through tissue, the trocar sleeve can function as a placeholder, allowing the endoscope and obturator to be removed. The endoscope can then be removed from within the obturator and reinserted through the trocar sleeve for use in performing various other procedures. In other embodiments, rather than using a trocar that houses the endoscope, an end cap can be removably disposed over a distal end of the endoscope. The present invention also provides methods and devices for shielding an endoscope during insertion through a body lumen, and in particular for preventing contact between the endoscope (or trocar sleeve) and the body lumen, thus preventing bacteria from being carried into a body cavity.

    摘要： A method for inserting an instrument through a natural orifice. The instrument has a low profile orientation and a deployed orientation which is larger than the size of the natural orifice through which it is to be inserted. The method is achieved by coupling the instrument to an endoscope and placing the instrument in its low profile orientation, insetting the endoscope and the instrument through a natural orifice to a target position within a body while the instrument is in its low profile orientation, actuating the instrument to it is deployed orientation, and returning the instrument to its low profile orientation and withdrawing the instrument from the body through the natural orifice.
