A system for anal and/or stomal irrigation of a user's bowel comprises a reservoir (102) for an irrigating liquid, a catheter (100) for insertion into the rectum and/or stoma of a user and for expelling of the irrigating liquid from a catheter tip, and an expandable retention element (104), such as a balloon, for fixation of the catheter tip within the user's rectum or stoma. Tubing and valve systems provide conduits for the irrigating liquid between the reservoir and the catheter and between the reservoir and the expandable retention element, a pump (101) being provided within the tubing system. The pump and the valve system is controllable to selectively pump the irrigating liquid into the expandable retention element, transfer the irrigating liquid through the catheter for expelling of the irrigating fluid from the catheter tip and into the user's rectum or stoma, and to withdraw the irrigating liquid from the retention element for purging thereof.

A system for anal and/or stomal irrigation comprises a reservoir (102) for an irrigating liquid, a catheter (100) comprising a catheter tip for insertion into the rectum or stoma of a user and for expelling of the irrigating liquid from the catheter tip, and a tubing system (121) providing a conduit for the irrigating liquid between the reservoir and the catheter tip. A pump (101) is provided to pump the irrigating liquid from the reservoir to the catheter tip, and a control system (103) controls a flow condition, such as the amount of liquid expelled at the catheter tip. A sensor (153) determines a measure of pressure in at least one first predetermined position in the tubing system and/or the catheter during operation of the pump, on the basis of which the flow condition is estimated. The control system is configured to control the pumping operation of the pump in response to the measure of pressure.

In general, devices, systems, and methods for surgical device activation detection using current sensing are provided. In an exemplary embodiment, a surgical system includes a surgical pump, a detector, and a surgical device. The detector is configured to sense changes in electrical power in an AC power line from an AC power source to the surgical device to detect activation of the surgical device. In response to the detection activation, the pump can properly provide suction pressure to the surgical device to allow the surgical device to provide aspiration at a surgical site during performance of a surgical procedure.

A method, including ejecting irrigation fluid from a distal end of a probe so as to irrigate tissue, and receiving, over a period of time, initial signals indicative of respective temperatures of the distal end, from a temperature sensor in the distal end. The method also includes formulating from the initial signals a temperature range between upper and lower temperature thresholds and, when a further signal from the temperature sensor, received subsequent to the period of time, is indicative of a further temperature above the upper temperature threshold, raising an alarm that a bubble is present in the irrigation fluid.

Fluidic devices, methods, and systems are disclosed. One system may comprises a sheath, a delivery module, and a removal module. The sheath includes a working lumen, a delivery lumen, and a removal lumen. The delivery module is configured to move a fluid from a fluid reservoir and into a body cavity through the delivery lumen. The removal module is configured to move the fluid and a particulate contained therein out of the body cavity through the removal lumen, through a filtration device that removes the particulate, and back into the fluid reservoir. One method comprises placing a distal end of sheath into a body cavity, energizing the working lumen to generate a particulate in the cavity, moving the fluid into the cavity to engage the particulate, and moving the fluid and the contaminant from the body cavity, through a filter for removing the contaminant, and back into the fluid source.

A method of determining a pressure of a body cavity with a controller of a fluid management system includes determining a pressure and a volume of a cuff disposed about a collapsible bag, determining a volume of the collapsible bag based on the pressure and the volume of the cuff, and determining a pressure of the collapsible bag based on the volume of the collapsible bag. The method also includes calculating a fluid flow from the collapsible bag into a body cavity from the collapsible bag and determining a pressure of the body cavity based on the fluid flow.

An irrigation balloon catheter includes one or more inner balloons inside of an irrigation balloon. The inner balloon(s) can be compliant with a volume that is dynamically adjustable for rapid inflation, rapid deflation, complete deflation, and/or irrigation flow adjustment. An inflator tool can be configured to inflate or deflate the inner balloon to adjust flow from the outer, irrigation balloon to affect temperature at electrodes of the irrigation balloon.

Systems and methods for cleaning a colon or other portion of an intestine include optional use of sensors to detect conditions of blockage of flow of materials within an evacuation channel used to remove fecal material from the body; and devices and methods for purging such blockages from the evacuation channel.

A lavage handle for facilitating at least one of an irrigation function and a suctioning function at a target zone preferably includes a portable body, a power-operated fluid-displacing mechanism in communication with said body wherein said fluid-displacing mechanism has one of a first operating mode for inducing outward irrigation of fluid towards the target zone and a second operating mode for inducing inward suction of fluid from the target zone. An actuation mechanism is located at said body and operable communicated with said fluid-displacing mechanism such that said fluid-displacing mechanism is selectively operated in at least one of said first operating mode and said second operating mode. The actuation mechanism may include an irrigation-inducing mechanism and/or a suction-inducing mechanism.
