A device and a method for a lavage-type introduction of a stool transplant or of another, local or topically effective substance through the anus into the colon of a patient, wherein the substance to be introduced is flushed also into the upper parts of the colon of the patient in a torrent-like manner through correspondingly large-lumen catheters; said device comprises an ano-rectal placed head part remaining inside the patient from the beginning until the end of the application and a system of exchangeable bags, which are connectable to the head part, whereby two different types of bags can be applied, one of which is designed for the cleaning lavage, while the another is designed for the introduction of a substance or a transplant.

In one embodiment, an irrigated medical system includes a medical tool, an irrigation line configured to fluidically connect an irrigation reservoir storing irrigation fluid to the medical tool, and provide at least some of the irrigation fluid to the medical tool, a force sensor configured to be coupled with the irrigation reservoir, and provide a signal responsively to a force exerted by the irrigation reservoir on the force sensor over time as irrigation fluid in the irrigation reservoir is depleted, and a controller configured to find an irrigation rate of the irrigation fluid flowing in the irrigation line responsively to the signal.

A method for anal or stomal irrigation includes providing an irrigation system to a user and instructing the user to operate the system to expel the irrigating liquid from a catheter tip. The irrigation pressure is controlled with the control system in response to input from a sensor such that a pressure at the catheter tip approaches a predetermined threshold pressure value without exceeding the predetermined pressure value.

An endoscopic system may include an endoscope including a handle and an elongate shaft extending distally from the handle, wherein the handle includes an inflow port in fluid communication with the elongate shaft, the inflow port being configured to fluidly connect to a fluid inflow line, an electronically adjustable orifice associated with the inflow port, and control circuitry for receiving a signal of a current size of the electronically adjustable orifice and/or for sending a signal to change a size of the electronically adjustable orifice. The system may include a first pressure sensor disposed upstream of the electronically adjustable orifice and a second pressure sensor disposed downstream of the electronically adjustable orifice.

A stool management system having a tubular body including a first end section disposable in a rectum of a patient and a second end section including a first connector which detachably mates with a second connector coupled to a collection container which receives waste matter passed through the tubular body from the bowel of the patient.

Methods of colon cleansing and/or inspection are described which safely maintain a colon in an uncollapsed state. Balanced replacement of a volume of fluid, gas and/or solids evacuated during cleansing of the colon is described. Replacement volume comprises, for example, cleansing fluid, jetting gas, and/or inflation gas. In some embodiments, balancing of evacuated and replacement volume is achieved under automatic control, based on monitored volume of material exchange, and/or measurement of resulting pressures.

A fluid management system may include an inflow pump providing a fluid inflow to a medical device, at least one pressure sensor, and a controller configured to receive pressure signals from the at least one pressure sensor, the pressure signals corresponding to a system pressure within the fluid management system. The controller may be configured to detect which one of a plurality of medical devices is fluidly connected to the inflow pump based on the pressure signals from the at least one pressure sensor and an rpm of the inflow pump.

A work tip for an ultrasonic surgical hand piece has a solid knife with a sharp distal edge. A first fluid tube located on one side of the knife and has open ends to receive or discharge fluid. A second fluid tube is located on the other side of the knife and is slidably connected with the knife. The second fluid tube has an opening at a distal end and a smaller side hole. During phacoemulsification the knife is vibrated independent of the fluid tubes. The second fluid tube has irrigation fluid passing from the opening and side hole, and the first fluid tube is positioned so as to receive fluid from the second tube. During I/A cleanup the second fluid tube receives aspiration fluid only through the side hole because the knife is positioned to block the aspiration fluid from entering through the opening.

A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

A disposable flushing and suction drainage tube and a-using method thereof comprises a flushing tube, a suction tube, and a mounting base. The flushing tube and the suction tube are respectively mounted at one end of the mounting base, and an air connector and a water connector are mounted at the other end; the mounting base comprises a tube body base and a control base, the flushing tube and the suction tube are mounted at one end of the tube body base, and the other end is detachably connected to the control base. The disposable flushing and suction drainage tube controls suction for the suction tube by a negative pressure adjusting opening on the mounting base; opening, closing, and water flow of the flushing tube is controlled by a water control switch on the mounting base, and switching between flushing and drainage and the flow of drainage can be controlled.
