Provided is a method of cleaning a body cavity using a device by coupling a distal end portion of a first cannula to the housing such that a lumen is in fluid communication with the first portion of the inner volume, the first cannula coupled to a vacuum source, then coupling a distal end portion of a second cannula to the housing such that a lumen is in fluid communication with the second portion of the inner volume, the second cannula being coupled to a fluid source, inserting a portion of the housing into a body cavity, conveying a fluid from the fluid source to the body cavity via the lumen of the second cannula, and withdrawing the fluid from the body cavity into the vacuum source concurrently with the conveying the fluid, via the lumen of at least the first cannula.

A multi-purpose balloon intra-cavity catheter includes a catheter having a proximal end portion, a central portion and a non-branching distal end portion, a plurality of lumens associated with the catheter extending from the proximal end portion, and a plurality of inflatable balloons positioned in the central portion and/or the non-branching distal end portion. Each of the plurality of inflatable balloons is communicatively associated with a corresponding one of the plurality of lumens, the plurality of inflatable balloons being selectively inflated or deflated to position and stabilize the catheter in a cavity for delivery of a medical treatment. The catheter can include an extraction opening associated with a lumen to remove fluids and materials from the cavity, and a connector associated with a corresponding lumen adapted to selectively receive one or more of a fluid medium or a radioactive isotope provided to a corresponding lumen for delivery of the medical treatment.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

A device for carrying out a lavage-like, repetitive supply and draining of a flushing, cleaning or other therapeutically active substance in the context of a return-flow enema, the device comprising: a catheter unit (SK) for receiving and draining feces, which can be permanently placed atraumatically and anorectally; a flushing and collecting bag unit (5, SB) with a combined flushing and collecting function; and a hose unit (4) connecting the catheter unit (SK) to the flushing and collecting bag unit (5, SB), comprising a single-lumen or multi-lumen, film-like, flatly collapsible, hose, and enabling a bidirectional flow communication between the catheter unit (SK) and the flushing and collecting bag unit (5; SB); characterized by at least one throughflow element with a flow-direction-dependent throttle function, providing a large lumen for draining of the patient's intestinal contents into the flushing and collecting bag unit (5; SB), so that shaped stool fractions can be drained, and which facilitates a supply of liquid from the flushing and collecting bag unit (5; SB) towards the patient, but wherein the supply of liquid towards the patient is throttled, so as to be reduced in flow amount or flow speed in relation to the draining of the patient's intestinal contents and thereby reduces the supply of liquid to the patient to a non-irritating amount that is compatible with the patient avoiding painful sensations and/or vegetative responses by an immediate dilation of the patient's colon and/or a triggering of a premature or only partially coordinated defecation reflex.

A fecal diversion tube system. Such a system includes an inflatable balloon, a fluid tube, and a fenestrated tube that bifurcates into a fluid port and an egress port. The system may be used to protect or ameliorate an anastomotic leak and may replace or reduce the need for diverting loop ileostomy following rectal resection.

Various devices, systems, and methods that can be used in the treatment of obesity and related illnesses are disclosed. In some instances, the cecum of an obese patient is distended to a pathophysiological size for a therapeutically effective period. The distention may be achieved by introduction of an object that is of foreign origin relative to the body of the patient into the cecum of the patient. In some instances, the distention is achieved by a medical device that transitions from an undeployed state, in which the medical device is introduced into the cecum of the patient, to an expanded state in which the medical device distends the cecum by an amount sufficient to trigger a colo-gastric brake in the patient.

A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

Systems, kits and methods are provided, which analyze the large intestine content and utilize acoustic signals detected during delivery of water into the large intestine and drained large intestine contents to derive large intestine characteristics such as microbiotal analysis. Systems may include a water delivery unit including a water supply and a nozzle connected thereto, configured to introduce water controllably into a patient's large intestine, and an analysis unit that provides information about the drained contents using optical examination or biological assays. The information may be related to acoustic analysis of signals from acoustic sensors that are attachable to a patient's abdomen. A variety of sensor configurations, positioning options, analysis strategies and large intestine characteristics are presented.

A method of treatment for mixed carbon dioxide, carbonic acid, saline and optional active additives for treating lower body cavity ailments includes delivery of dosage of the treatment at specified flow rates, using a) main housing having a hollow central area containing the dosage; b) a dosage dispenser head located at the distal end of the main housing, and having at least one flow channel for movement of the dosage from the main housing through the dosage dispenser head and to external of the dosage dispenser head; c) a dosage release control component located between the main housing and the dosage dispenser head to permit flow of the dosage through the dosage dispenser head in response to increased pressure against the dosage; and d) a pressure-changing moveable component on the main housing.
