Medical devices and systems for treating stenosis, such as along the biliary and/or pancreatic tract, are disclosed. An exemplary system may include a guidewire having a distal end and defining a lumen. A stiffener may be slidably disposed within the cavity. The stiffener may have a distal end and a distal region disposed adjacent the distal end. The stiffener may be configured to transition between a first position in which the distal end of the stiffener is disposed proximal to the distal end of the guidewire and a second position in which the distal end of the stiffener is disposed distal to the distal end of the guidewire. 公开了用于治疗狭窄，例如沿胆道和/或胰腺道的医疗设备和系统。示例性系统可以包括导丝，其具有远端并限定了腔。加强杆可以可滑动地设置在腔内。加强杆可以具有远端和远端区，远端区与远端相邻设置。加强杆可以配置为在第一位置和第二位置之间转换，在第一位置中加强杆的远端设置在导丝的远端的近侧，在第二位置中加强杆的远端设置在导丝的远端的远侧。
