ABSTRACT:
The dilation balloon of the subject invention preferably comprises a balloon portion mounted about a shaft that, when inflated, produces a configuration comprising a tapered distal end and a proximal end or butt that is substantially flat (preferably truncated) and is adapted to generally conform with the outer contours of an endoscope through which it is introduced when the balloon is pulled back against the endoscope face. The close engagement of the subject balloon catheter and endoscope, when forming a balloon-scope train, enables the scope to more readily navigate strictures and tortuous body lumen, as well as allows the balloon to act as a lens for viewing anatomical structure within the body lumen, such as tumors, strictures, and the inner luminal wall surface itself.
