In some non-limiting examples, a system for stimulating tissue growth at a tissue site may include a porous foam and a moisture barrier. The porous foam may include an exterior-facing surface, a tissue contact surface, and a plurality of struts positioned at the tissue contact surface. The plurality of struts may be configured to contact the tissue site and to create tissue deformation at the tissue site without the application of a reduced pressure. The moisture barrier may be configured to cover the exterior-facing surface of the porous foam and to trap moisture at the tissue site. Also provided are other systems, apparatus, and methods suitable for stimulating tissue growth.

Granulating dressing for low exuding chronic wounds

A system and apparatus for promoting perfusion at a tissue site containing a sprain by applying a vacuum to intact skin extending over or surrounding the tissue site. The system and apparatus comprise a manifold formed from a porous material and configured to be disposed proximate the intact skin for distributing vacuum to the intact skin, and a sleeve adapted to cover the manifold and form a chamber containing the manifold to seal the manifold within the chamber between the sleeve and the intact skin. The system and apparatus further comprise a fluid coupling member adapted to deliver vacuum to the manifold for distribution to the intact skin. A method for applying vacuum to the intact skin of a tissue site is also disclosed and described herein.

System and method utilizing vacuum for promoting the healing of sprains

Skin graft harvesting systems and methods are disclosed that utilize sensors to automate the harvesting of skin grafts or assist a user in deciding when the skin graft is ready to be harvested. Such systems and methods can reduce the burden of visual observation and ensure greater reliability and consistency of the grafts. The invention is particularly useful with harvesters that rely upon suction and/or heating to raise a plurality of small or 'micro' blisters simultaneously.

Sensor systems for skin graft harvesting

The present application relates to devices and methods for harvesting skin graft sheets. The present invention provides a blister raising device comprising a blade assembly for cutting a blister sheet and an array of protrusions configured to prevent a portion of skin at the donor site from blistering.

Devices for creating an epidermal graft sheet

Devices and methods for skin graft harvesting are disclosed. In one aspect of the invention, substrates for transplanting skin grafts are disclosed that include a soft-tack, biocompatible composition having a surface adapted to contact at least one excised skin graft and engage the graft for removal from a donor site. In another aspect of the invention, at least a portion of the skin-contacting surface of the substrate (or dressing) is porous to facilitate fluid transport into (or out of) the graft site during harvesting and/or transplantation. The substrates can also incorporate an absorbent component to capture fluids. The substrate can be a mesh or fabric or web, e.g. woven, knitted, nonwoven or molded. The substrate can be a mesh of biocompatible fibers, for example, cellulosic, polyolefins, polyurethanes, polyesters or polyamide fibers. In one embodiment the mesh is formed of cellulose acetate fibers and coated with a silicone gel, to imparted the desire degree of tackiness.

Soft-tack, porous substrates for harvesting skin grafts

The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.

Apparatus and method for administering reduced pressure treatment to a tissue site

The present invention generally relates to devices and systems that utilize an inflatable bladder for generating, cutting, capturing, and/or transplanting one or more skin blisters. In some aspects, methods and devices in accordance with the present teachings can enable the harvesting of skin grafts from an increased variety of potential donor sites, such as areas of the body having uneven surfaces or a smaller radius of curvature (e.g., the arm) or large area donor sites where the creation of a vacuum may require a high power negative pressure source. In various aspects, systems, devices, and methods in accordance with the present teachings can also enable the efficient transplant of the grafts directly from the skin graft harvester to the recipient site without the transfer of the grafts generated by the harvester to another substrate prior to transplantation.

Hydraulically actuated skin graft harvesting

A reduced pressure treatment system includes a distribution manifold having a backing substrate with a first side and a second side and a plurality of protrusions positioned on the first side of the backing substrate. Each of the protrusions includes a substantially circular cross-sectional shape and has a diameter of between about 0.1 and 2.0 millimeters, the backing substrate having a plurality of apertures formed therein to allow fluid communication between the first side and the second side opposite the first side. A reduced pressure source is fluidly connected to the apertures of the backing substrate to deliver the reduced pressure through the apertures, between the protrusions, and to a tissue site.

Reduced pressure wound dressing having a wound contact surface with columnar protrusions

A wound exudate removal and isolation system includes a porous dressing, a canister in fluid communication with the dressing, and a first valve positioned between the dressing and the canister. The first valve is positionable between an open position and a closed position. A disposal line is fluidly connected to the canister and includes a second valve that is positionable between an open position and a closed position. A pump is fluidly connected to the canister and is configured to draw wound exudate from the dressing into the canister when the first valve is open and the second valve is closed. The pump is configured to force wound exudate from the canister into the disposal line when the first valve is closed and the second valve is open.

Wound exudate removal and isolation system

A reduced pressure treatment system is provided for delivering a reduced pressure to a tissue site comprising a distribution manifold including a backing substrate with a first side and a second side and a plurality of protrusions positioned on the first side of the backing substrate, each of the protrusions having a substantially circular cross-sectional shape and having a diameter of between about 0.1 and 2.0 millimeters, the backing substrate having a plurality of apertures formed therein to allow fluid communication between the first side and the second side opposite the first side. A reduced pressure source fluidly connects to the apertures of the backing substrate to deliver the reduced pressure through the apertures, between the protrusions, and to the tissue.
