The present disclosure provides medical devices and techniques for enhancing formation of vapor bubbles by laser energy in a liquid medium. In particular, the present disclosure is directed at a liquid medium with a tendency to develop and/or sustain a gaseous state in the presence of laser energy and a system to both irrigate a treatment site with the liquid medium and irradiate a target in the liquid medium.

Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

The present invention relates to a medical instrument for the targeted introduction of a substance into a body cavity and to a tool (1) therefor. According to the invention, the tool (1) has a shaft (2) with a lumen (6), on the distal end (1″) of which is situated a nozzle head (3) with at least two nozzles (4), wherein the nozzles (4) are spaced from each other at an angle of less than 180° and equally relative to a centre axis (M) of the shaft (2).

A catheter with an electrode assembly has a functional electrode located at a first position on the electrode assembly and a shunting electrode located proximal to the first position. Irrigation fluid carried by the catheter may be electrically coupled with a patient's blood through the shunting electrode. The shunting electrode may be used to reduce noise in an electrocardiogram signal that results from the pump used to supply the irrigation fluid.

Surgical tools are provided herein that are configured to apply suction and irrigation at a surgical site during the course of a surgical procedure. A surgical tool can include a handle that has a suction flow path configured to provide suction therethrough and an irrigation flow path configured to provide irrigation therethrough. The suction flow path and the irrigation flow path can share a common path along at least partial lengths thereof. An elongate shaft can extend distally from the handle and can have an inner lumen that is in communication with the suction flow path and the irrigation flow path. The inner lumen can thus be configured to provide suction from the suction flow path to a surgical site to remove matter therefrom and to provide irrigation from the irrigation flow path to the surgical site to provide fluid thereto.

Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described, Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. In one example embodiment, a system for providing negative-pressure and instillation to a tissue site may comprise a negative-pressure device and an instillation device. The negative-pressure device may comprise a negative-pressure source and a controller electrically coupled to the negative-pressure source. The instillation device may comprise a dosing valve having a dosing chamber including a dosing outlet configured to be fluidly coupled to a fluid port and a dosing inlet configured to be fluidly coupled to a source of instillation solution. The dosing valve may also have a working chamber including a biasing element operably engaged to the dosing chamber and configured to be fluidly coupled to the negative-pressure source. In some embodiments of the system, the instillation device may further comprise a wireless transceiver configured to communicate with the controller, and at least one sensor coupled to the wireless transceiver to provide a signal indicative of an operating condition of the dosing valve, and wherein the wireless transceiver is configured to communicate the at least one signal to the controller.

There is disclosed in one example an ear irrigation system, including: a control unit including a fluid reservoir; a disposable earpiece constructed to interface with a human subject's ear canal; an extension unit configured to receive the disposable earpiece and to impart fluid to an ingress port of the disposable earpiece; and an umbilical to fluidly couple the fluid reservoir to the extension unit; wherein the control unit is programmed to, responsive to an input from an operator, pump fluid from the fluid reservoir to the extension unit; and wherein the disposable earpiece includes a plurality of vortical fluid guides to guide fluid from an ingress port to an egress port, and to impart to the fluid at the egress port a vortical motion to delaminate a cerumen impaction from the human user's ear canal.

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.
