This invention relates to a small bell-shaped latex rubber protector that is designed to be placed over the top of, e.g., an endoscope prior to its passage into a body cavity through a tract thereof. Once it is passed in a folded back position, a sharp, pointed or cutting foreign object can be retrieved from the cavity using a forceps or other accessory. The protector hood is then flipped into the open position by pulling the instrument back through, e.g., the lower esophageal narrowing. The bell-shaped latex protects, for example, the esophagus and posterior pharynx from the foreign body during its removal.
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.
