A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

A surgical apparatus for use by a surgeon can include a tray and a plurality of surgical instruments. The tray can have a plurality of structures located on an upper side of the tray for receiving the plurality of surgical instruments. The tray can receive a separate control unit. The tray can also have a fluid reservoir receiver for receiving a bottle or container of fluid, such as balanced salt solution. The fluid reservoir receiver can include one or more features, including, a spike, an air vent, and a light. A separate container can be used to place the bottle or container of fluid into the fluid reservoir receiver on the tray. This separate container can include a collapsible section.

A liquid dispenser having a liquid reservoir for storing liquid, an elongated nasal applicator, a nozzle plate with a plurality of nozzle openings at a distal end of the nasal applicator through which liquid is discharged, and a conveying device conveying liquid from the liquid reservoir to the nozzle openings. The conveying device has a movable pressure element serving to pressurize the liquid for discharge. The conveying device has an actuating handle, displaceable for the purpose of actuation, from a starting position into an actuated end position. The actuating handle and the pressure element are connected via a spring accumulator loaded by displacement of the actuating handle into the end position and which accumulator subsequently moves the pressure element. The actuating force stored in the accumulator subsequently continues to move the pressure element once actuation has already concluded and thus brings about an ongoing discharge.

Methods of treating a medical condition in a patient include performing a lipectomy of visceral fat to remove a quantity of the visceral fat from the subject. The removal of visceral fat treats the medical condition such that the subject experiences at least a reduction of symptoms of the medical condition.

There is provided a colon cleaning device comprising: a tube through which liquid and fecal matter are removed from a colon of a patient, the tube having a longitudinal axis; a cleaning head positioned at the distal end of the tube, the cleaning head having at least one opening coaxial with the longitudinal axis, the at least one opening sized for fecal matter to enter the interior of the cleaning head from the colon; at least one disassembly element disposed within the cleaning head; and an actuating mechanism which actuates the disassembly element to perform sweeping displacement inside the cleaning head so that the at least one disassembly element rotates around the longitudinal axis to slice through the fecal matter; wherein the cleaning head and the tube are sized and shaped to be displaced along the colon of a patient.

A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

A nasal irrigation device and system is described that provides gentle and effective irrigation of the nasal cavity. Small volumes of irrigation fluid are directed towards the wall of the sinus cavity and collected centrally, using a pliable irrigation device. A focusing feature is provided that serves to hold the attention of children undergoing nasal irrigation in order to distract them from the procedure. Such a focusing feature can be in the form of a stuffed or toy animal that envelops or forms part of the nasal irrigation system.

An apparatus, including a pump body having an internal shaft, and a piston disposed within the shaft and having a piston head that includes a first ferromagnetic element. The apparatus also includes a motor coupled to drive a reciprocal longitudinal motion of the piston within the shaft, and a pump chamber configured to be removably attached to the pump body and having a rigid wall defining a fluid inlet, a fluid outlet, and an aperture. The apparatus additionally includes a flexible diaphragm fixed across the aperture and having a second ferromagnetic element, which engages the first ferromagnetic element when the pump chamber is attached to the pump body so that the reciprocal longitudinal motion of the piston causes alternating stretching and contraction of the flexible diaphragm, thereby modifying a volume of the pump chamber.

A method and apparatus for injecting saline into an open cavity of a patient's body, and, alternatively, vacuuming fluids from said cavity, during laparoscopic surgery that provides constant feed and amplified pressure to provide a steady fluid output, in a disposable, single use handheld surgical device. The apparatus has a pump portion that includes a vacuum powered pump motor with a spring-biased valve.

A surgical control system in communication with a plurality of surgical devices includes a surgical pump configured to control a flow of surgical fluid to an operating site. A camera apparatus of the plurality of surgical devices is configured to capture image data depicting a surgical site. A system controller is configured to capture image data demonstrating the surgical site, identify a visibility metric of the image data, and determine a control setting for the surgical pump in response to visibility metric below a visibility threshold.
