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: A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods for controlled delivery of a stent, such as a self-expanding stent, and more particularly for controlling the full deployment of a stent in incremental steps from a sheath and for controlling the reconstrainment of a stent in incremental steps within a sheath.

Abstract: A medical device may include a snare loop and an elastic member that connects at least two sides of the snare loop. The elastic member is configured to transition from an unexpanded state where the elastic member is in a plane of the snare loop to an expanded state where the elastic member is outside the plane of the snare loop. The snare loop has a same shape when the elastic member is in the unexpanded shape and the expanded shape.

Abstract: Stent delivery device includes an inner member having a distal tip, a stent disposed over a stent receiving region of the inner member, an outer sheath slidable over the inner member, a stent sheath removably coupled to both the distal tip and a distal end of the outer sheath, and a stent expanding element attached to the distal tip and/or the distal end of the outer sheath. The stent expanding element is biased in an elevated position and aids expansion of the stent when the stent sheath is removed. The stent delivery device includes a proximal junction removably coupling the distal end of the outer sheath to the stent sheath, and a proximal junction removably coupling the stent sheath to the distal tip. Each of the proximal and distal junctions are separately actuatable to decouple the stent sheath from either the distal tip or the outer sheath.

Abstract: An esophageal atresia bridge device including a proximal anchor, a distal anchor, and a brace extending between the proximal anchor and the distal anchor. The brace permits the proximal anchor to move toward the distal anchor to apply a controlled tension that pulls the esophagus together and stretches the esophagus over time. A method of treating esophageal atresia may include inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region, and rotating the rotatable member relative to the elongate member to longitudinally move the distal end of the elongate member relative to the rotatable member in order to apply a force to a proximal pouch of the patient's esophagus.

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.
