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 sizing tube having a distal end portion including a plurality of apertures. The control valve enables suction to be applied to the patient's stomach via the apertures to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the sizing tube to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

Gastric sizing systems including instruments for use in bariatric surgery

The invention provides a vacuum tube attachment device for vacuum assisted wound dressings. The device is in the form of a patch that can be attached to the primary wound cover. The patch forms a substantially air-tight seal to the primary wound cover, and a vacuum tube is fixed to the patch such that the patch can be oriented on the wound cover to locate the tube near an opening in the cover to allow vacuum pressure to be communicated to the wound. The patch has an adhesive area around its perimeter for attaching the patch in a substantially air-tight seal to the wound cover at any convenient location on the cover. Several embodiments of the patch are described.

Tube attachment device for wound treatment

A system for applying suction to a wound is provided, including a suction source for providing suction to a conduit operatively associated with the wound to communicate suction to the wound, a vent in fluid communication with the conduit to provide a reference airflow into the conduit when the system is in operation, such that a loss of suction at the wound is indicated by deviation from the reference airflow, and a waste collector canister between the wound and the suction source for collecting liquids aspirated from the wound, wherein the canister includes one or more disks containing gelling agent.

System for treating a wound with suction and method of detecting a loss of suction

A suction regulator arranged to be coupled to a source of partial vacuum and a patient circuit and which is operative in four modes is disclosed. A first mode isolates the source of partial vacuum from the patient. A second mode provides continuous regulated suction to the patient. A third mode provides intermittent regulated suction to the patient. The fourth mode provides unregulated full suction to the patient. The regulator includes a movable control knob for establishing the first, second, third and fourth modes and a detent mechanism holding the control knob in the position to select the desired mode. An interlock is also provided to prevent the control knob from being accidentally moved to the position establishing the unregulated full suction mode.

Suction regulator having four modes of operation

A therapeutic device for promoting the healing of a wound in a mammal is disclosed. An exemplary device comprises a permeable structure having a plurality of depressions formed in a surface thereof. In use, the surface having the depressions is disposed adjacent a surface of the wound. A method of manufacturing a therapeutic device for promoting the healing of a wound in a mammal comprising the steps of providing a permeable substrate, and forming a plurality of depressions into a surface of the permeable substrate to provide the therapeutic device. A method of treating a wound comprises: providing a permeable structure comprising a plurality of randomly disposed fibers and having i) a plurality of wound surface contact elements disposed between end portions of the structure, and ii) a plurality of voids defined by the contact elements; and applying the permeable structure to at least one surface of the wound.

Wound dressing with a discontinuous contact layer surface

A wound packing for use with suction is provided. The wound packing comprises a plurality of nonabsorbent synthetic polymeric fibers coupled together to form a nonabsorbent material suitable for placement in the wound of a mammal. A method for treating the wound in a mammal using the disclosed wound packing is also provided.

Wound packing material for use with suction

A tunnel dressing for use in treating a tunneling wound using negative pressure wound therapy. The tunnel dressing includes an elongate permeable member having a closed distal end for entering the wound and an open proximal end into which an applicator is removably disposed for guiding the dressing into the wound. The tunnel dressing has a support structure adapted to transport wound exudates away from the wound and to resist compression under suction. The tunnel dressing also has a wound contact surface adapted to minimize tissue entanglement to facilitate removal. The support structure and wound contact surface may be formed from the same material or from two adjacent layers of different material.

Tunnel dressing for use with negative pressure wound therapy system

A system for applying suction to a wound uses a reference airflow for monitoring system operation. A reference airflow (or 'controlled leak') to the suction source is provided when the system is in operation, such that deviation from the reference airflow can be monitored as an indication of a change in operation, such as a leak in the seal of the wound cover, a blockage of airflow from crimping of the suction conduit or overfill of the waste collector, or an inadvertent turn off or disconnect from the suction source.

A method of treating a wound comprises the steps of providing a permeable structure comprising a plurality of randomly disposed fibers and having i) a plurality of wound surface contact elements disposed between end portions of the structure, and ii) a plurality of voids defined by the contact elements; and applying the permeable structure to at least one surface of the wound.

Method of treating a wound utilizing suction

A system for treating a wound with suction is provided. The system comprises a wound cover, a pump having an input port and an output port, the input port providing suction to the wound via the wound cover, and a reservoir coupled to the output port of the pump. The reservoir is adapted to receive effluent from the wound and the pump is capable of maintaining a controlled level of suction at the wound.
