Abstract: A cannulation device is adapted to gain access to the patient's common bile duct. In some instances, the cannulation device includes a first guidewire lumen extending through an elongate shaft and terminating at a first oblique guidewire port, and a second guidewire lumen extending through the elongate shaft and terminating at a second oblique guidewire port. In some instances, the cannulation device includes an inflatable balloon that is inflatable from a collapsed configuration to an expanded configuration in which the inflatable balloon is adapted to occlude the patient's pancreatic duct. In some instances, the cannulation device includes an expandable element that is expandable from a collapsed configuration in which the expandable element is disposed within the guidewire lumen and an extended configuration in which a portion of the expandable element extends distally from a guidewire port.

Abstract: The present disclosure provides a tissue debridement device and describes an example treatment for ANP using the tissue debridement device. The tissue debridement device has a sheath, a distal tip, and a plurality of rotating tines coupled to the distal tip and the sheath. The distal tip can be adjusted to be closer or further from the sheath to change a diameter of the rotating tines, thereby changing a cutting diameter of the tissue debridement device.
