Abstract: An endoscopic plug for performing an endoscopic procedure includes an external housing and internal tubing for securing within a body cavity opening, the external housing including a plurality of support tabs to secure the external housing to an exterior of the body cavity opening, and the internal tubing including an expandable balloon on an outer surface for expanding within the body cavity to secure the plug within the body cavity. The support tabs, expandable balloon and other features help to create a sealed internal environment for performing water aided endoscopy (“WAE”). The endoscopic plug additionally includes an air passage within the internal tubing to inflate the expandable balloon, sloped edges adjacent to the support tabs to seal the external housing to an external opening of the body cavity, and a plurality of valves, seals and pumps which allow for the introduction and retention of liquid into the body cavity.

Abstract: Systems and methods for removing a material from a lumen or duct include a guide wire to navigate to the material and a cutting assembly that can then be guided along the guide wire to reach the material. A proximal wire end can be connected to a pump device configured to provide an irrigation substance along a delivery channel of the guide wire and release the irrigation substance at a distal wire end. A power source can apply a current to the guide wire to magnetize a coupling assembly disposed on the guide wire. The cutting assembly can couple to the guide wire by engaging a locking mechanism of the cutting assembly with a coupling assembly of the guide wire.

The locking mechanism can receive torque provided by a motor coupled to the proximal wire end of the guide wire to rotate the cutting tool of the cutting assembly to remove the material.

Abstract: A cassette with free flow prevention for use with an ambulatory pump. The cassette includes a free flow prevention clamp and a housing. The free flow prevention clamp includes a clamping section having a first side and a second side, a first elongate section extending from the first side, and a second elongate section extending from the second side. The housing supports the free flow prevention clamp and defines a channel for receiving a tube. The elongate sections extend parallel to the channel and the clamping section extends across the channel. The free flow prevention clamp is configurable within the housing in an open condition that allows fluid flow through the tube when force is applied to one of the elongate sections and in a closed condition that prevents fluid flow through the tube when the force is removed from the elongate sections.
