Abstract: Medical devices and systems for treating a stricture, for example along the biliary and/or pancreatic tract, are disclosed. An example system may include a guidewire having a distal end and defining a lumen. A stiffening rod may be slidably disposed within the lumen. The stiffening rod may have a distal end and a distal end region disposed adjacent to the distal end. The stiffening rod may be configured to shift between a first position where the distal end of the stiffening rod is disposed proximally of the distal end of the guidewire and a second position where the distal end of the stiffening rod is disposed distally of the distal end of the guidewire.
