A system for feeding and aspirating a patient's stomach may include a feeding bag, a collection bag, and a water source interconnected with each other via a double action piston pump and further connected to a nasogastric tube via the double action piston pump. An exemplary double action piston pump may be utilized for pumping contents of the feeding bag into the patient's stomach, pumping out contents of the patient' s stomach into the collection bag, injecting water from the water source into the patient's stomach.

An automatic pump-based fluid management system, as described herein, comprises an intercostal pump that is, generally, a resiliently flexible bulb having an inlet and an outlet. The inlet is attached to a first tube that extends from the intercostal pump to a first area of a patient's body, for example, the patient's pleural cavity. The outlet is connected to a second tube that extends from the intercostal pump to a second area of a patient's body, for example, the patient's peritoneal cavity. In use, the intercostal pump is placed between a first rib and a second rib in a patient. The intercostal pump operates by being successively compressed and decompressed between the first and second ribs as the patient breaths.

A smoke evacuator for use with a surgical access device includes an evacuation ring having an inner peripheral surface defining one or more channels therein disposed in fluid communication with an operating cavity. A connection port is disposed thereon in fluid communication with the channel(s) and adapted to connect to a smoke evacuation system. The evacuation ring includes a profile having an inner flange that forms part of the inner peripheral surface of the evacuation ring and one or more lower flanges, the inner flange is configured to mechanically engage a rim of an access device and the lower flange(s) is adapted to mechanically engage a wound guard, wherein engagement of the inner flange of the evacuation ring atop the access device and engagement of the lower flange(s) with the wound guard secures the access device, the wound guard and the smoke evacuation ring within the operating cavity.

A portable urinal device includes a base forming a liquid receptacle. Tubing extends from the base to a head member which can be positioned onto genitalia for urination. Suction is provided via a pump or vacuum device to suction urine from the head into the base receptacle.

A system for providing a force to a desired area on a curved body part of a person includes a dressing assembly shaped and configured to be placed on the desired area of the person, a releaseable circumferential member surrounding the curved body part that holds the dressing assembly against the desired area, a sealing subsystem for providing a fluid seal over the dressing assembly and the person's skin, and a reduced-pressure subsystem for providing a reduced pressure to the dressing assembly. When reduced pressure is supplied, the system generates the force against the desired area on the curved body part.

A surgical drain device includes an adhesion matrix of biodegradable polymer material and a plurality of drain tubes attached to the matrix. The device is implanted within a surgical wound to treat the presence of seromas, for example, and is used to promote drainage, tissue adhesion, and wound closure. The drain tubes converge into a common collection tube that leads wound fluid outside the body under gravity feed or negative pressure applied to the collection tube. The matrix contains an array of apertures that allow tissue contact across the device. The device also can include a coating of surgical adhesive and a tissue anchoring system of hooks or barbs. The device can be used with a negative pressure system to further improve the drainage band can also be used with a wound dressing. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.

Manifold structures, systems, and methods are disclosed that include using longitudinal members and one or more shaped projections to cause microstrain at a tissue site. In one instance a manifold structure includes a plurality of spaced longitudinal members and at least one shaped projection coupled to at least one of the plurality of longitudinal members for creating a microstrain at a tissue site. The at least one shaped projection includes a columnar member having a distal end and includes an enlarged member positioned at the distal end of the columnar member. The columnar member has a first outer diameter (D.sub.1) and the enlarged member has a second outer diameter (D.sub.2). The second outer diameter of the enlarged member is greater than the first outer diameter of the columnar member (D.sub.2>D.sub.1). Other systems, methods, and structures are presented.

An apparatus and method for aspirating, irrigating and/or cleansing wounds is provided. The apparatus and method include one or more of the following: simultaneous aspiration and irrigation of the wound, supplying of thermal energy to fluid circulated through the wound; supplying physiologically active agents to the wound; a biodegradable scaffold in contact with the wound bed; and application of stress or flow stress to the wound bed.

The present invention relates to a suction device. The suction device comprises an attachment portion adapted to be attached to a wound cover member. The suction device comprises a fluid inlet which is at least partially circumscribed by the attachment portion. The suction device also comprises a fluid outlet. The suction device further comprising a connection portion adapted to, at least during one operation condition of the suction device, provide a fluid communication between the fluid inlet and the fluid outlet. The connection portion comprises an inspection portion that is transparent to thereby facilitate the positioning of the suction device relative to the wound cover member.

A surgical cassette for use with a phacoemulsification system having a front plate, a back plate, and a gasket therebetween. The front plate having molded fluid channels that mate with the gasket. The gasket having multiple valves and a sensor or diaphragm accessible through the back plate.
