The invention provides a fluid management system (1) for providing fluid from a fluid source (20) to the body of a patient. The fluid management system (1) includes a compressible chamber (10). A fluid conduit (30) is in fluid communication with the fluid source (20) and with an interior of the compressible chamber (10). A bypass conduit (40) has an inlet end (43) in fluid communication with the fluid source (20) and an outlet end (44) for providing fluid to a trocar (70). The bypass conduit 40 passes either through or around the compressible chamber (10). A first one way valve (80) can admit fluid from the fluid conduit (30) into the interior of the compressible chamber (10). A second one way valve (90) can admit fluid within the interior of the compressible chamber (10) into the bypass conduit (40). A portion (46) of the bypass conduit (40) upstream of the second one way valve (90) is collapsible under the force of selectively applied external pressure when the compressible chamber (10) is at least partially filled with fluid from the fluid source (20), so as to selectively close off the bypass conduit (40) upstream of the second one way valve (90).

An enema assist device is provided. The device includes a support and the support is configured to be placed on a toilet bowl such that the support front is oriented towards the front of the toilet bowl. The support is configured to support a fluid delivery tip such that the fluid delivery tip is disposed on the top surface of the support and protrudes at least partially beyond a plane defined by a top of the toilet seat.

Fluid management in surgical procedures. At least some of the illustrative embodiments are methods including: supplying fluid to a surgical site inside a patients body, drawing fluid from the surgical site through a first instrument by a first pump at a first flow rate, the first flow rate during the drawing responsive to expected or actual visibility within the surgical site; and then performing a surgical resection within the surgical site using the first instrument, the performing the surgical resection changes the first flow rate; and adjusting, by a fluid management system after the surgical resection, the first flow rate responsive to the expected or actual visibility within the surgical site.

Systems, methods, and apparatuses for providing instillation therapy with a negative-pressure source are described. The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.

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 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.

Variables of a surgical system are detected or received via one or more sensors to predict an intraocular pressure (IOP) and/or determine an IOP in real time during a surgical procedure. A notification to a surgeon or a target IOP is set and maintained as determined by Static IOP, dynamic IOP, and/or a total IOP combining both static and dynamic IOP of the anterior chamber of a patient's eye. Information collected about various components of the system are displayed on a user interface. The system uses the collected information to calculate the static IOP and/or dynamic IOP of the system, and the total IOP may be function of the static IOP and/or dynamic IOP measurements.

Systems and methods for cleaning body cavities are presented. Described embodiments include systems for cleaning feces from the lower GI tract. Also provided are systems for steering such a cleaning system, also useful for steering an endoscope or other tool inserted into a body.

A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent gelling of blood, and maintain drainability.
