Abstract: A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.

Abstract: An endoscope (e.g., a duodenoscope) includes a bifluidic valve for controlling the flow of a liquid (e.g., water) and a gas (e.g., air) through a flexible tubular probe to respectively irrigate or insufflate an internal cavity of a patient. The bifluidic valve can be a single component, an interconnected assembly of components, or a plurality of separate components. Some examples of the bifluidic valve include a stepped diameter valve spool with radial or circumferential fluid passageways. In some examples, the bifluidic valve includes a tube pincher that can stop the water or other liquid from flowing through a flexible tube by pinching the tube shut. Some example bifluidic valves include a valve housing that is resiliently flexible to urge the valve to a normally closed position. In some examples, selectively covering or uncovering a vent in the valve housing controls the flow of air for insufflation.
