Disclosed is an irrigation system. The irrigation system includes a manual pump. The manual pump can provide pressurized liquid through a tube at an outlet.

A system and method for providing fluid to a tissue site is described. The method fluidly couples an instillation therapy system to the tissue site and monitors a pressure supplied to the tissue site by a reduced-pressure source with the instillation therapy system for a time period. The method provides fluid to the tissue site with the instillation therapy system in response to the pressure at the tissue site during the time period. The system includes a pressure sensor fluidly coupled to the tissue site to measure a pressure proximate the tissue site. A valve and a flow meter are fluidly between a fluid reservoir and the tissue site. A controller is communicatively coupled to the pressure sensor and the valve and configured to monitor the pressure at the tissue site and a volume of fluid flow to the tissue and, in response, operate the valve.

An ear disimpactor for disimpacting material impacted in an ear canal and against a tympanic membrane, is disclosed. The impacted material comprises cerumen, insects, and other debris. The ear disimpactor comprises a housing, a warm water irrigation unit, and a suction unit. The housing comprises an ear speculum attached to an outer surface of the housing, a motorized auger comprising a drill bit extending from the motorized auger to a tip of the ear speculum, a warm water line extending from the tip of the ear speculum and across a length of the housing, and a suspension suction tube extending from the tip of the speculum and across the length of the housing. The warm water irrigation unit provides warm water to the ear canal through the warm water line and the suction unit sucks out suspension from the ear canal.

A method of managing fluid conditions in a patient involves advancing at least one medical instrument into a target organ of a patient, the at least one medical instrument comprising an irrigation channel and an aspiration channel, coupling the at least one medical instrument to an irrigation fluid source, providing irrigation from the irrigation fluid source into the target organ through the irrigation channel of the at least one medical instrument, determining an irrigation pressure limit based at least in part on one or more case-specific parameters, providing irrigation into the target organ through the irrigation channel, and limiting the irrigation based at least in part on the determined irrigation pressure limit.

An assembly structured for concurrent irrigation and aspiration of a nasal cavity including a housing having a supply container disposed therein for the removable retention of irrigating fluid. A nasal applicator comprises first and second passages respectfully structured to deliver irrigating fluid to the nasal cavity and concurrently remove waste fluid therefrom. An activating assembly includes a plunger biased into a continuous pressure applying, dispensing relation to the irrigating fluid and a valve assembly is selectively disposable into an open position facilitating fluid communication between the supply container and the applicator for the delivery of the irrigating fluid therethrough into the nasal cavity. The activating assembly is further structured to create a negative pressure within the chamber which communicates with the second passage of the applicator to facilitate delivery of the waste fluid therefrom along a path of travel to an interior of the chamber.

An ultrasonic aspirator includes a body, an aspirator wand extending from the body, a shield to cover the aspirator wand, a removable headpiece removably attached to the aspirator wand, and a guard extending past an end of the headpiece in a direction distal to the body. the aspirator also includes a generator or a detector to generate or detect electrical pulses, light sources, endoscopy, modified body angles, image navigation integration for improved visualization and optimization of the surgical field.

Various arrangements of fluidics systems are disclosed. In one arrangement, an aspiration circuit for a fluidics system is disclosed that selectively controls aspiration. The aspiration circuit comprises an aspiration line operatively connected to a surgical instrument, an aspiration exhaust line operatively connected to a waste receptacle; an aspiration vent line connected at a first end to the aspiration line; and a selectively variable vent valve operatively connected to the aspiration vent line. The variable vent valve may be selectively moved to vary aspiration pressure within the aspiration line. Other fluidics systems are disclosed that include a selectively positionable irrigation valve that may also be incorporated into a fluidics system that includes a variable vent valve.

A system for performing irrigation of a body cavity includes a reservoir containing an irrigation liquid, a catheter and a controller. The catheter is configured to be at least partially inserted into the body cavity and has a flushing passage, a drain passage and a retention balloon. A waste drain valve is in fluid communication with the drain passage of the catheter and is movable between a closed configuration, where waste is retained within the drain passage, and an open configuration where waste flows through the drain passage. The controller is in fluid communication with the reservoir and the catheter, and has a pump and a valve assembly. The valve assembly is changeable between configurations where, when the pump is actuated, irrigation liquid is pumped from the reservoir to the retention balloon, from the reservoir to the flushing passage of the catheter and from the retention balloon to the reservoir.

A fecal collection device includes a barrel with a waste drain conduit attached thereto. A drain opening is defined between passages of the barrel and the waste drain conduit. An irrigation conduit is connected to a source of lavage liquid. A trocar plug has a tapered distal end and moves between insertion, irrigation and flushing positions within the barrel passage. When in the insertion position, the tapered distal end of the trocar plug extends from the distal end of the barrel. When in the irrigation position, the irrigation conduit may provide lavage liquid to the barrel passage while the trocar plug covers a majority of the drain opening. When in a flushing position, the trocar plug covers less of the drain opening than when the trocar plug is in the irrigation position.

An adapter for a surgical hand piece having a single lumen work tip with an open end and a small lateral hole is designed to convert the work tip to infusion/aspiration (I/A) cleanup of lens epithelial cells after phacoemulsification. The adapter is in the form of a sleeve adapted to be slid over the distal end of the work tip. The sleeve includes at least one aspiration hole located toward the distal end of the sleeve. When the distal end of the sleeve is at a first distance L.sub.1 from the distal end of the work tip, aspiration occurs through the aspiration hole of the sleeve and the open end of the work tip. When the distal end of the sleeve is at a second and smaller distance L.sub.2 from the open end of the work tip, aspiration through the open end of the work tip is blocked by the sleeve and aspiration occurs through the aspiration hole of the sleeve and the lateral hole in the work tip.
