Abstract: An ostomy bag device includes a bag with first and second chambers communicating via a first opening and a pressure sensitive interface. The bag includes a second opening interfacing with a stoma exit and receiving waste in the first chamber, a third opening expelling the waste from the first chamber, and a fourth opening releasing gas from the second chamber. The interface transitions from a first state in which the interface prevents a gas flow through the first opening from the first to second chambers and a second state in which the interface allows the flow. A first pressure differential in the first chamber relative to the second chamber causes the interface to assume the first state preventing the flow and a second pressure differential in the first chamber relative to the second chamber higher than the first differential causes the interface to assume the second state allowing the flow.

Abstract: A multi-electrode energy-delivering assembly configured to be delivered in a generally elongate delivery configuration. The multi-electrode energy-delivering assembly includes one or more spaced apart electrodes of a first polarity. The electrodes may be spaced apart axially and/or may be expanded apart from one another upon deployment. In some aspects, the electrodes may be electrically activated independently of one another.

Abstract: Bipolar or monopolar adjustable energy-delivering assemblies. The assemblies are configured for transluminal (e.g., endoscopic) delivery within a patient. A first energy-delivering member defines a first electrode portion formed of an electrically-conductive material so that energy may be delivered to the first energy-delivering member to create an energy field along the first electrode portion to apply to a target site within a patient. The first energy-delivering member may define a lumen therethrough allowing delivery of materials distally therethrough to a target site and/or allows materials from the target site to be aspirated proximally therethrough. Optionally, a second energy-delivering member and a second insulation member form a second electrode portion. Optionally, either or both electrode portions may be adjustable. Additionally or alternatively, the first electrode portion and the second electrode portion are adjustable with respect to each other.

Abstract: An energy-delivering assembly probes formed from an elongated energy-delivering member have one or more electrodes defined along an energy-delivering region of the energy-delivering member. An electrode-defining insulation member is provided over the energy-delivering member to define and space apart at least a first electrode from a second electrode. One or more of the electrodes and/or insulation members are configured and/or have characteristics or properties which reduce/minimize/eliminate arcing between/across electrodes of the energy-delivering assembly.
