This application presents methods and devices for continuously cleaning a colon by at least partially filling a segment of the colon with liquid and agitating the fluid to dislodge matter adhering to the colon walls. Methods for automatic maintenance of liquid levels in the colon during continuous cleaning are taught.

A catheter for measuring temperature of a fluid in a body cavity includes a catheter body having a proximal end and an opposite distal end with a tip; an inflow lumen; an outflow lumen; and a temperature sensor lumen having a temperature sensor. The temperature sensor lumen is arranged closer to the outflow lumen and to the inflow lumen in the catheter body. The temperature sensor includes a sensing element positioned at the tip of the distal end to measure a temperature of a fluid in a body cavity when the distal end of the catheter body is inserted into a body cavity.

Disclosed is a medical instrument for use in minimally invasive therapy that generates, by at least two independent devices, an aspiration that advantageously causes the stability of the distension and the viewing conditions by adjusted flow rates.

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 apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are moved by a device (which may be a single pump or two pumps) for moving fluid through a flow path which passes through the dressing and a means for providing simultaneous aspiration and irrigation of the wound. The apparatus also comprises means to apply high frequency vibrational energy, e.g. ultrasound, to the wound bed. The former removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter promotes healing. The dressing and a method of treatment using the apparatus.

A system for detecting intraocular pressure events during phacoemulsification surgery having a surgical console, a handpiece having a proximal end being communicatively connected to an irrigation line and an aspiration line; a first sensor in communication with the aspiration line or the irrigation line for providing a first measurement value; and a second sensor in communication with the aspiration line for providing a second measurement value; and wherein at least one characteristic of the irrigation fluid or aspiration fluid in their respective lines is changed in accordance with the difference between the first measurement value and the second measurement value. A system for calibrating patient eye level and wound leakage; detecting occlusion or post occlusion surge; determining BSS usage or remaining in a container; and detecting a fluid line abnormality using a first sensor and a second sensor in different configurations and differences in first and second measurement values.

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.

A trans-anal irrigation (TAI) system adapted for self-use includes an irrigation head supplied with water from a reservoir by a pump or by gravity feed. The irrigation head has either internal or external structures for releasably retaining the head in a user's rectum during the water flow portion of a TAI process. A guide member arm may be provided for manipulating the irrigation head for both insertion and removal. The irrigation head is reliably attached to the guide member arm. The guide member arm may include an integral manual pump.

A system and method to irrigate a user's auditory canal. A fluid can be dispensed from a reservoir through a fluid path and out through openings of a delivery element into the auditory canal. A pump may be used to facilitate the process of dispensing the fluid. The fluid can be delivered to the user's auditory canal for a predetermined period of time. Such a time period may be user selectable. The discharge from the irrigation is removed from the user's auditory canal via a discharge port located on the delivery element. The discharge exits the delivery element and proceeds to a discharge reservoir via a discharge path. A vacuum may be used to generate a negative pressure to facilitate the removal of the discharge from the auditory canal.

The present patent application relates to a device for rinsing body cavities, as they are used, for instance, in the hysteroscopy, that determines, by using flow sensors, the introduced and discharged amount of rinsing liquid. Based on these flow measurements, it can be determined whether a relevant amount of liquid has been left in the patient.
