Provided are devices, systems, and methods related to dressings with regions with different adhesive properties, and manufacture and use thereof. An illustrative dressing includes a first region including a first adhesive material. The first adhesive material has a first tackiness. The dressing further includes at least a second region including a second adhesive material. The second adhesive material has a second tackiness in a first phase and a third tackiness in a second phase. The third tackiness is greater than the second tackiness. The first adhesive material is configured to maintain the first tackiness when the second adhesive material is in the second phase.

Drapes with regions with higher adhesive properties

In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Dressing providing apertures with multiple orifice sizes for negative-pressure therapy

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.

Manifolding apparatus or dressing exhibiting low tissue ingrowth and negative-pressure treatment method

An assembly includes a drape substantially sealable over a wound bed and a trackpad configured to couple a tube to the drape and allow the tube to provide suction to the wound bed. The assembly also includes a vent opening in the drape, a filter coupled to the drape and communicating with the vent opening, a cover coupled to the drape and movable between a first position to cover the vent opening and filter and a second position to uncover the vent opening and the filter, and a fluid indicator coupled to the drape and operable to provide a visual indication that fluid build-up is present in the wound bed.

NPWT system with selectively controllable airflow

Aptamer-modified polymers and materials thereof, used for binding factors in a wound bed. The aptamer-modified materials can be polypeptides conjugated to polymer foam materials and used, for example, as dressings, wound inserts, or pads.

Aptamer-modified polymeric materials for the binding of factors in a wound environment

The present invention provides aptamer-modified polymers and materials thereof, which may be used for the binding of factors in a wound bed. For example, the aptamer-modified materials can be polypeptides conjugated to polymer foam materials. Such materials may be used, for example, for dressings, wound inserts, or pads.
