The wound drainage apparatus for drug-assisted removal of bodily fluids includes a double-lumen tubing member connected to a customizable branched tubing member for placement in a wound cavity. A perforated inner tube connected to an anticoagulant drug delivery pump and a solid outer tube connected to a fluid drainage vacuum make up the double-lumen tubing member. The branched tubing member includes a plurality of secondary wound cavity tubes branching away from a primary wound cavity tube. The apparatus disclosed herein improves upon current drainage systems by preventing occlusions produced by blood clots forming in fluid drainage tubes.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible member having a distal end portion arranged for anchoring the instrument in the patient's stomach and for enabling fluids to be removed from the patient's stomach. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

Systems, apparatuses, and methods for providing negative pressure with instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, a system may comprise a tissue interface adapted to be coupled to a source of instillation fluid and a dressing interface having a therapy cavity that includes a pH sensor, a humidity sensor, a temperature sensor, and a pressure sensor embodied on a single pad within the dressing interface to provide data indicative of acidity, humidity, temperature and pressure at the tissue site. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage conditions as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise disposing the tissue interface at the tissue site and the therapeutic cavity in fluid communication with the tissue interface. The method may further comprise instilling fluid to the therapy cavity and then sensing the pressure, humidity, temperature, and the pH of the fluids adjacent the tissue interface. The method may further comprise determining various flow characteristics of the system by using a processing element electrically coupled to the sensors for transmitting property signals from the sensors to a controller configured to assess the property signals in order to identify the flow characteristics.

A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

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.

A skin treatment device includes a control unit and a hand tool. The hand tool includes a body, a wiper head, and a needle roller head. The wiper head includes a rotatable wiper structure including one or more wiper blades. The needle roller head includes needle roller structure. The skin treatment device provides a multi-step process including desincrustation, skin transdermal delivery of topical agents, serums, and the like, microdermabrasion, and fractional micro-channeling application.

A matter elimination catheter includes a catheter body extending from a catheter proximal portion to a catheter distal portion. The catheter body includes an infusion lumen, an aspiration lumen fluidly isolated from the infusion lumen, and a septum interposed between the infusion and aspiration lumens. A drive shaft is within the infusion lumen and is configured to provide rotation near the catheter distal portion. A guide wire lumen is within the drive shaft, and the infusion lumen, the drive shaft and the guide wire lumen are fluidly separated from the aspiration lumen with the septum. In one example, fluid bearings are formed between one or more of the catheter body and drive shaft or the drive shaft and a guide wire or guide wire liner when supplied with infusion fluid through the infusion lumen.

Apparatus and methods are provided for delivering fluids into a patient's body that includes a tubular member including a proximal end, a distal end sized for introduction into a patient's body, and a fluid delivery lumen extending between the proximal and distal ends; and a flexible pad on the distal end including a tissue contacting surface, a passage communicating with the fluid delivery lumen, and plurality of capillary channels in the tissue contact surface communicating with the passage, the capillary channels configured to deliver fluid from the fluid delivery lumen and passage to tissue contacted by the tissue contact surface.

The present solution provides trans-round window membrane (RWM) drug delivery. As an overview, the system can include a micropump that is connected to a flexible cannula. The cannula can include a stiffened and sharpened tip to facilitate insertion through the RWM. The cannula can be inserted through the RWM to improve the distribution of the delivered drug throughout the inner ear. The present solution can function as a small implantable or wearable device that can be used for both chronic and acute trans-RWM drug delivery. With this configuration, the micropump can constantly or intermittently deliver, over a period of days to months, small volumes of drugs from an internal reservoir.
