Connection pads for coupling fluid-instillation and negative pressure wound therapy (NPWT) apparatuses to wound dressing, and methods and wound dressings for breaching a drape after coupling a wound dressing to a fluid-instillation and/or NPWT apparatus.

A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

A RF weldable film is provided. The film has outer layer including a PVDF copolymer or an alpha-olefin polymer and backing layer including a TPU copolymer. The film may have a gas barrier layer attached to the backing layer. The backing layer may include an EVOH copolymer. A method of making such a film is also provided. Containers made from such film are further provided.

A polygonally shaped carbon nanotube (CNT) sheet optical bellows providing enhanced stray light suppression, the polygonally shaped CNT sheet optical bellows includes: a free-standing non-woven CNT sheet; a polymer bonded to the non-woven CNT sheet; and an elastomer film bonded to the polymer film, creating a laminate film, the laminate film being rolled to form a cylinder by applying an adhesive along a bonding edge of the laminate film to adhere the bonding edge to an opposite edge of the laminate film, an outer side of the laminate film comprising diamond-shaped elements, the diamond-shaped elements being pinched, pressed, folded and collapsed in a rotating manner around a circumference of the cylinder, creating the polygonally shaped CNT sheet optical bellows.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.

An article may include a first polymeric material layer having a surface. A first conductive trace may form at least a portion of the first layer surface. The article may further include a second polymeric material layer. The second layer may have a first surface, a portion of the second layer first surface being bonded to a portion of the first layer surface. The second layer may have a portion of a channel defined therein, the channel at least partially coinciding with a portion of the first conductive trace. The article may also include a first patch interposed between the first layer surface and the second layer first surface. The first patch may span the channel and cover a portion of the first conductive trace.
