Abstract
Device and method for treating tissue inside a patient's body, the device including an endoscopically introducible catheter shaft. The endoscope is constructed for insertion into the patient's body, and has a channel passing through it. The channel terminates at an opening in the distal end of the endoscope. The channel enables the catheter shaft to pass through the endoscope and beyond the distal end of the endoscope. A chamber is mounted on the catheter shaft. The chamber is defined by a flexible wall. The chamber is associated with a first lumen defined by the catheter for fluid flow between the chamber and a fluid source outside of the patient's body. The chamber is fillable with fluid after placement in the patient's body. When the chamber is filled with fluid it has a diameter greater than the diameter of the transverse cross-section of the endoscope channel. According to the method, the endoscope is inserted into a patient's body and is used to view the inside of the patient's body, to determine the location of tissue to be treated. The catheter is inserted into the channel that passes through the endoscope. The chamber is filled with fluid and is positioned at the location of tissue to be treated.

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.
