Abstract
Medical devices and systems for treating a stricture along the biliary and/or pancreatic tract are disclosed. An example medical device may include a guidewire for use along the biliary and/or pancreatic tract. The guidewire may include an elongate core member having a proximal end region and a distal end region. A coil member may be disposed along the distal end region. An actuation member may be coupled to the coil member. The actuation member may be configured to shift the coil member between a first configuration and a compressed configuration. The coil member may be configured to be advanced across a biliary and/or pancreatic stricture when in the compressed configuration. A sleeve may be disposed over the coil member.
