Abstract: A system for providing a force to a desired area on a curved body part of a person includes a dressing assembly shaped and configured to be placed on the desired area of the person, a releaseable circumferential member surrounding the curved body part that holds the dressing assembly against the desired area, a sealing subsystem for providing a fluid seal over the dressing assembly and the person's skin, and a reduced-pressure subsystem for providing a reduced pressure to the dressing assembly. When reduced pressure is supplied, the system generates the force against the desired area on the curved body part.

Abstract: An anisotropic wound drape for treating a wound on a patient includes a flexible sheet for placing over a tissue site. The flexible sheet includes a first isotropic zone, and a second isotropic zone. The first isotropic zone and the second isotropic zone are configured to provide the flexible sheet with anisotropic stretching properties. The anisotropic drape may used as part of a reduced-pressure wound treatment system. Other systems and methods are also presented.

Abstract: Systems, apparatuses, and methods for providing negative pressure with instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, a system may comprise a tissue interface adapted to be coupled to a source of instillation fluid and a dressing interface having a therapy cavity that includes a pH sensor to provide data indicative of acidity/alkalinity at the tissue site. Such apparatus may further comprise algorithms for processing such data for providing information relating to the progression of healing of wounds at the tissue site.

Abstract: Tissue dressing materials and associated methods of forming such dressing materials are disclosed. In one example embodiment, a dressing material may include a foam and a film formed on a first side of the foam. The film may be integrally-formed on the side of the foam. The film may include a plurality of apertures. A method of making the dressing material may include placing a pre-polymer mixture and water into a mold to create the dressing material comprising a foam and an integral film on at least one surface of the foam. The method may further include forming a plurality of openings in at least the integral film, with the openings being formed within the mold or subsequent to removal of the dressing material from the mold.

Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage conditions as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise disposing the tissue interface at the tissue site and the therapeutic cavity in fluid communication with the tissue interface. The method may further comprise instilling fluid to the therapy cavity and then sensing the pressure, humidity, temperature, and the pH of the fluids adjacent the tissue interface. The method may further comprise determining various flow characteristics of the system by using a processing element electrically coupled to the sensors for transmitting property signals from the sensors to a controller configured to assess the property signals in order to identify the flow characteristics.
