Abstract: An endoscopic capsule adapted for selective attachment to the distal end portion of an endoscopic device. The capsule is designed for insertion with an interconnected endoscopic device into a patient body to provide an open space in front of the distal end of the endoscopic device. The capsule facilitates the performance of endoscopic procedures providing a space in which to manipulate medical instruments within the patient body as well as improving a surgeon's field of vision within the patient body. In one embodiment, the capsule includes a housing having an internal chamber and two apertures. A first aperture is interconnectable to the end of an endoscopic device and provides operative access to endoscopic instruments contained therein. One or more of these endoscopic devices are advanceable into the internal cavity for selectively engaging patient tissue disposed relative to the second aperture.
