A method of treating human or animal tissue, the method comprising the step of: i. directing a stream of an aqueous liquid comprising gas bubbles excited by acoustic energy towards a wound or anatomical pocket in human or animal tissue, or towards an anatomical space or potential space in human or animal tissue, or towards soft or hard tissue in an oral cavity or elsewhere in the human or animal body, or towards tissue in a nasal cavity, or towards tissue associated with sinuses, eye, ear, digestive and genito-urinary systems, thereby to treat the human or animal tissue with the stream. The output stream can clean a wound in human or animal tissue, and can treat the wound by healing the wound, for example by stimulating fibroblasts in the wound tissue and causing, promoting or enhancing re-epithelialisation of epidermal tissue in the wound.

Disclosed are various embodiments for an anti-reflux enema bucket system that is leakproof, easy to disassemble and clean, prevents reflux, has components that can be independently cleaned and sanitized, and controls a rate at which water is expelled from a nozzle outlet. In various embodiments, the enema bucket system includes an enema bucket having an opening at a top for filling the enema bucket with solution, a nozzle comprising a nozzle outlet, an anti-reflux coupler positioned between the enema bucket and the nozzle through which the solution passes from the enema bucket to the nozzle outlet; and tubing fluidly coupling the enema bucket, the anti-reflux coupler, and the nozzle. A pulley restrictor may selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.

An enema device for washing a large intestine that can supply water to a large intestine to easily wash and defecate the large intestine. The enema device for washing a large intestine includes a nozzle part inserted into an anal passage and having an ejection hole for ejecting water at one end thereof; a balloon part coupled to an outer peripheral surface of the nozzle part to be expanded; an air pump configured to supply air to the balloon part; a switching valve, to which the air pump is connected; a first water hose, an air hose, and a second water hose; the nozzle part has a discharge hole through which air supplied from the air hose is discharged to the balloon part.

A pump and pump controller which uses an algorithm to quickly achieve and maintain a stable plasma field in a surgical site are provided. The algorithm calculates an electrical characteristic value to determine if the suction rate by the pump should be increased or decreased to achieve a stable plasma field. A method of using such a pump and pump controller is also provided.

Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

A device, a system and a method are provided to accurately apply a medically beneficial substance directly to a laterally or superiorly located paranasal sinus cavity. When the device is assembled with a solution in a reservoir, and inverted such that the reservoir is above an input apparatus and a housing, weight of the solution pushes down on a diaphragm creating a negative pressure on the diaphragm, which prevents air from entering the reservoir and prevents a liquid from flowing out of the reservoir. Applying a positive pressure to a bottom of the diaphragm causes the diaphragm to open and allows air to flow into the reservoir. When a user creates the positive pressure by exhaling air into the device the act of exhaling causes the user's choana to close. Thereby any solution introduced into the user's sino-nasal cavity will remain contained within the user's sino-nasal cavity increasing effectiveness of treatment and decreasing user discomfort including gagging, choking, and inner ear disturbance. When the positive pressure on the bottom of the diaphragm is removed, the flow of the liquid from the reservoir stops.

Kidney stone removal system is disclosed having components including a handle mechanism, a nozzle tip, and a guiding device. The handle mechanism employs a trigger that enables control of irrigation and vacuum/suction. Depression of a trigger in the trigger mechanism conveys status of vacuum/suction and irrigation to a user by providing increased resistance at different points of depression. When the trigger is in a home (undepressed) position, irrigation and vacuum/suction are turned off. When the trigger is in a fully depressed position, irrigation and vacuum/suction are turned on. When the trigger is in an intermediate position, irrigation may be turned on, while vacuum/suction remains turned off. The nozzle includes one or more irrigation ports positioned at a distal end of the nozzle and having an irrigation port departure angle of 30 to 60 degrees for directing irrigation fluid forward and laterally from the distal end of the nozzle. The guiding device is configured to be removably positioned in the nozzle for receiving a debris fragmentizing device, such as a laser device. The guiding device is configured to prevent an unintended movement of the fragmentizing device when the fragmentizing device is positioned in the nozzle while allowing fluid and debris to flow past the fragmentizing device and through a vacuum tube.
