A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array. The longest principal axis of each ellipsoid may be perpendicular to the array. Each truncated ellipsoid may be a spheroid and/or may include an approximately elliptical contact surface at each contact surface between two interconnected ellipsoids. Each fluid pathway may have four continuously-curved concave sides and may have a parallelogram-shaped cross-section with continuously-curved concave edges. A dressing may include the apparatus, a dressing layer coupled to the apparatus, a backing layer disposed over a surface of the dressing layer opposite the apparatus, and an attachment device disposed on at least a margin of the backing layer. Methods of treating various tissue sites using the apparatus or dressing with negative-pressure therapy are also disclosed.

Dressings for treating a tissue site with negative pressure are disclosed, which may include a dressing having at least three layers assembled in a stacked relationship. In one example embodiment, a first film may comprise a non-porous material and a plurality of fluid restrictions. A first manifold layer may be adjacent to the first film and may comprise a second film of a transparent material having blisters and a manifold area. The first manifold layer may further comprise apertures configured to allow fluid transfer through the second film. A second manifold layer may be adjacent to the first manifold layer and may comprise foam having a contact area that is less than the manifold area of the first manifold layer.

A negative pressure wound closure devices, systems and methods. Embodiments of the invention facilitate closure of the wound by preferentially contracting under negative pressure to provide for movement of the surrounding tissues. Some embodiments may utilize a stabilizing structure with a plurality of cells configured to collapses more in the x-direction than in the y-direction.

This relates to a wound therapy device, including an outer part and an inner part facing surface provided with an inner part facing opening, and a first connection channel to establish fluid communication between the inner part facing opening and a connector opening adapted to be connected to an external device. The wound therapy device can also be a part of a wound therapy arrangement, which can further include, a wound filler, an external device, a wound cover film, and tubing connections. Methods of using the wound therapy arrangement are also disclosed.

A process of manufacturing a wound dressing filler and/or wound dressing.

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.

Disclosed are solid and frozen haemostatic materials having a rod shape and suitable applicators and plungers for application of such dressings to wounded tissue wherein said dressings consisting essentially of a fibrinogen component and a fibrinogen activator. Also disclosed are methods of treating internal wounded tissue in a mammal by applying one or more of these haemostatic materials and dressings, particularly for the treatment of injured tissue via endoscopic or minimally-invasive surgical techniques.

A surgical portal apparatus includes a sleeve having a proximal end and a distal end that extends along a longitudinal axis, and a surgical tape. The sleeve includes an inner wall defining an internal longitudinal passageway dimensioned for permitting passage of a surgical object therethrough and an outer wall configured for positioning against tissue. The inner and outer walls define at least a partial annular space therebetween, the annular space being in fluid communication with an opening in the outer wall. The surgical tape includes a body portion retained within the annular space of the sleeve and a leading tab extendable through the opening in the outer wall of the sleeve. The surgical tape has a first surface and a second surface, each of the first and second surfaces having at least one of tissue reactive functional groups and self-reactive functional groups.

A wound packing material is provided, suitable for use in negative pressure wound therapy, including a body of a porous material, the body including frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. Methods of manufacturing the wound packing material, and methods of its use are also provided.
