Abstract: A method for calculating range of motion of a patient's jointed limb includes providing one or more locators at an upper limb of the jointed limb, and one or more of the locators at a lower limb of the jointed limb. A first image of the patient's joint in a fully extended position a second image of the patient's joint in a fully flexed position are captured with an imaging device. The method includes identifying positions of the locators of both the first image and the second image, and determining an extended angle of the patient's joint based on the identified positions of the locators of the first image. The method includes determining a flexed angle of the patient's joint based on the identified positions of the locators of the second image. The method includes determining a range of motion angle based on the extended angle and the flexed angle.

Abstract: A dressing includes a barrier film layer, a wound contact layer coupled to the barrier film layer, and a plurality of felted foam strips positioned between the barrier film layer and the wound contact layer. Each strip provides a manifolding pathway. The barrier film layer and the wound contact layer include a central region and a plurality of peninsular projections extending therefrom in the shape of a hand.

Abstract: A dressing includes a first manifold layer, a second manifold layer, a first barrier layer coupled to the first manifold layer, a second barrier layer coupled to the second manifold layer, a first fenestrated film layer coupled to the first manifold layer, and a second fenestrated film layer coupled to the second manifold layer. The first manifold layer and the second manifold layer are positioned between the first barrier layer and the second barrier layer. The first fenestrated film layer and the second fenestrated film layer are positioned between the first manifold layer and the second manifold layer.

Abstract: Disclosed dressing embodiments may include a tissue interface and a cover, with the tissue interface shaped anatomically for interaction with a specific anatomical region, such as a foot. Such tissue interface embodiments would typically comprise a manifold and a fluid control layer having a plurality of fluid restrictions, with the manifold disposed in a stacked relationship with the fluid control layer. Some embodiments of the tissue interface might also include a gel layer in a stacked relationship with the fluid control layer, opposite the manifold. For foot dressings, tissue interface embodiments may be shaped with a hindfoot section, an underfoot section, and a forefoot extension section.

Abstract: A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

Abstract: A dressing assembly for use with a reduced pressure treatment system, the dressing assembly develops a directed force under reduced pressure. The directed force may be a radial force or a closing force. The dressing assembly includes a shaped dressing bolster having a shaped extremity that is operable to evenly deliver the radial force and to distribute reduced pressure. Numerous shapes may be used for the shaped extremity. The dressing assembly may further include an over-drape to assist in creating a seal over the shaped dressing bolster and against a portion of a patient's epidermis.

Abstract: An indicator configured to be attached to a wound dressing includes first and second parts. The wound dressing is configured to collapse in response to an applied negative pressure. The first and second indicator parts are configured to move relative to one another as the wound dressing is collapsed. The movement of the first and second indicator parts is configured to allow a user to easily visualize the compression of the wound dressing and monitor the application of the negative pressure to the wound dressing. A marker is provided along a top surface of the first part and a window is formed on the second part. The changes in the portion of the marker that is visible in the window as the first part is slid into or under the second part are configured to provide for easier detection of the collapse of the wound dressing by the user.

Abstract: A release liner, for example for use with a tissue cover having a first adhesive and a second adhesive, may comprise a first release agent adapted for the first adhesive and a second release agent adapted for the second adhesive. Typically, the first release agent is different from the second release agent, and the first release agent may be configured to interact with a first area of the cover having the first adhesive, and the second release agent may be configured to interact with a second area of the cover having the second adhesive. In some embodiments, the release liner may be multi-layered, for example with a first layer comprising the first release agent and a second layer comprising the second release agent. Some such embodiments may have perforations through the second layer of the release liner, with the first layer then being disposed with respect to the second layer in such a way as to expose the first release agent through the perforations in the second layer.

Abstract: A dressing includes a foam layer, a plurality of cores extending substantially through the foam layer, and a drape sealable over the foam layer and a wound bed. The drape is couplable to a pump operable to create a negative pressure in the substantially-airtight volume. Each core is substantially removable from the foam layer to reveal a channel through the foam layer. Each core is defined by perforations that facilitate separation of the core from the foam layer.
