Abstract: A barrier for use in negative pressure wound therapy can include a base layer and surface structures. The barrier can be used to reduce or prevent tissue ingrowth. A method of using a negative pressure wound therapy system can include positioning a perforated barrier in a wound. After positioning the perforated barrier in the wound, positioning a pad in the wound on top of the perforated barrier, positioning a seal on top of the wound to at least partially seal the perforated barrier and the foam in the wound, and applying negative pressure wound therapy to the wound.

Abstract: A mechanical wound therapy (MWT) system includes a connection for a vacuum source, which is routed through an airtight covering to a porous material positioned over the wound. The porous material may be a tubing network interspaced by a netting material constructed of biologically inert or bioabsorbable material. Alternatively, the porous material may be a layered unified dressing in which layers of mesh, netting or thin perforated film are separated and fixedly attached to functional elements of the dressing (e.g., irrigation tubing) or spacers. The vacuum and irrigation systems may be completely separated. An airtight sealing layer or foldable adhesive sealing layer may seal the dressing and facilitate sealing the dressing to the wound margins. Additional modular devices such as a wound approximating system, positive pressure bladders and adjuvant therapy modules as well as enhanced monitoring technology can be added to synergistically increase the capabilities of each dressing.

The dressing system may further include a tube coupled to the sponge for removing fluid from the sponge. The dressing system comprises: a sponge; and a tensioning system coupled to the sponge. The tensioning system further comprises a central longitudinal member coupled to the sponge; and at least one tensioning member coupled to the central longitudinal member. A sequential compression system comprises: an envelope sleeve dressing; and a bladder that is both expandable and retractable. A tissue filler system is also described and includes a plurality of tubes; wherein each of the plurality of tubes further comprises apertures; and a pump coupled to at least one of the tubes which obviates the need for any sponge or wound screen.

Abstract: A method and system for continually monitoring oxygenation levels in real-time in compartments of an animal limb, such as in a human leg or a human thigh or a forearm, can be used to assist in the diagnosis of a compartment syndrome. The method and system can include one or more near infrared compartment sensors in which each sensor can be provided with a compartment alignment mechanism and a central scan depth marker so that each sensor may be precisely positioned over a compartment of a living organism. The method and system may comprise hardware or software (or both) may adjust one or more algorithms based on whether tissue being monitored was traumatized or is healthy. The method and system can also monitor the relationship between blood pressure and oxygenation levels and activate alarms based on predetermined conditions relating to the oxygenation levels or blood pressure or both.

Abstract: Systems, devices, and methods related to wound therapy are disclosed. Different aspects of wound care, including mechanical wound therapy, wound monitoring, irrigation, debridement, and delivery of therapies to the wound surface can be combined to improve effectiveness of treatment. The disclosed techniques can provide various type of clinical applications of wound therapies, including reverse pulse lavage, gas therapy, bacterial count measurements, pressure-based ulcer prevention, pain management, peritoneal dialysis, and controlled tissue in-growth, among others. In some instances, the systems described herein can be made portable and operable without the use of electricity, which provides potential to provide mechanical wound therapy in settings without access to extensive clinical facilities.

Abstract: A method and associated system are provided for implementing lottery ticket transactions via a player's mobile device and a retailer's existing gift card interchange system hosted by a gift card service provider without issuing an actual gift card. Purchase of the lottery ticket at the POS location mimics purchase of any other product using a gift card at the POS, which allows the retailer to conduct lottery transactions by piggybacking their existing gift card system provider's network.

Abstract: An auditing system and method is configured to capture and report an interactive client journey between a web browser and a website. Instantiation of control code at an end-user computing device brings about the capture of server and request headers from the perspective of the locally-executing web browser. The control code causes the sending of an uplink journey report to a cloud-based processing server that uses the report to interpret the server and request headers to imply real-time interactions between the end-user. Capture may be based on AJAX requests related to end-user interaction; and data calls made to the e-commerce server during the web session. Client-side capture provides installation of control code that can be delivered directly from a content distribution network. The processing server correlates the server and request headers with predefined flagged events.
