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.

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: 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 wireless near-infrared spectrometry sensor includes a light source for emitting near-infrared energy into tissue and a light receiver for receiving the near-infrared energy after it exits the tissue. The sensor may include a portable energy source for supplying energy to the light source. A processing module may control the light source and process readings in connection with the light source. A wireless transceiver may be coupled to the processing module for at least one of transmitting and receiving information, wherein the light source emits near-infrared energy at predetermined intervals in order to conserve energy in the portable energy source. The portable energy source may include at least one of a battery, a capacitor, a thermoelectric generator, a kinetic energy transducer, electricity derived from RF energy, and any combination thereof. The sensor may further include a substrate for support and which may be part of a sterile bandage.

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.
