Abstract:
1. An apparatus cooperable with a grasping slot of an elevator for an endoscope having a proximal end defining an endoscope port, the apparatus comprising: an expandable balloon disposable through the endoscope for dilating a stricture in the body duct; and a catheter disposable about the expandable balloon and cooperable with the grasping slot of the elevator to secure the catheter at a stricture, the catheter comprising proximal and distal portions along a longitudinal axis thereof, the proximal portion comprising a scored splittable portion formed therealong to define first and second sections separable from each other by the scored splittable portion, and the distal portion being unscored and structured not to be split for protecting and maintaining the expandable balloon at the stricture, the first and second sections configured to be peeled from each other by tearing the scored splittable portion, thereby distally moving a point of peeling from the proximal end of the catheter until the point of peeling abuts the endoscope port such that the catheter is unable to distally move, the distal portion being secured in a longitudinal position relative to the balloon and maintaining the expandable balloon at the stricture.
