Abstract
An endoscopic assembly, utilizing a braided mesh material as an expandable sheath, is disclosed. The mesh sheath is adapted to receive an endoscope for viewing the interior of a body cavity or lumen and one or more channels for performing medical procedures within the patient. The mesh sheath expands laterally as it is compressed longitudinally, which allows it to come into contact with the interior of the body cavity. By doing so, it can anchor the assembly, take samples from the body cavity, or dilate a stricture in the body cavity. Additional dilation procedures can be performed by removing the endoscope and inserting other instruments without removing the entire assembly from the patient. The body cavity can be hermetically sealed to reduce the risk of contamination of the endoscope and channels.
