Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
