Abstract: A tubeset module includes one or more elements of a negative pressure wound therapy (“NPWT”) system, such as a valve, a calibrated leak, a pressure sensor, etc. The tubeset module may communicate with a controller of the NPWT system via a communications interface provided by the tubeset module. The communication between the tubeset module and the controller may be used to fully automate one or more processes involving the operation of the components of the NPWT system included in the tubeset module, allowing the NPWT system to, e.g. estimate a wound site volume, estimate a volume of fluid to be instilled, monitor wound healing progression, etc. without requiring any user interaction or involvement. The tubeset module may be defined by one or more housing elements. The tubeset module may be incorporated into any of the tubing, fluid canister, wound dressing and/or therapy device housing components of the NPWT system.

Abstract: The present disclosure relates to a network system. The system is formed by at least two negative pressure wound therapy (NPWT) devices. The first NPWT device includes a wireless radio, user interface, controller, and processing circuit. The wireless radio wirelessly communicates with the second NPWT device. The user interface displays operational status of therapy operation, receives a command of operational change from a user, and displays wireless radio connection strength between the first NPWT device and the NPWT device. The controller controls therapy operation of the first NPWT device based on input from the user interface. The processing circuit causes the wireless radio to communicate with the second NPWT device, determines wireless radio connection strength between the first NPWT device and the second NPWT device based on communication between the first NPWT device and the second NPWT device, and causes the user interface to display determined wireless radio connection strength.

Abstract: A wound therapy system includes a dressing an instillation pump fluidly communicable with the dressing and configured to provide instillation fluid to the dressing, a negative pressure pump fluidly communicable with the dressing and configured to remove air from the dressing, and a control circuit communicably coupled to the instillation pump and the negative pressure pump. The control circuit is configured to control the instillation pump to provide an amount of the instillation fluid to the dressing, provide a soak period, and control the negative pressure pump to provide a cyclic variation of negative pressure at the dressing.

Abstract: Systems and methods for providing negative-pressure therapy with fluid instillation therapy and, more specifically, scheduling and controlling both the negative pressure therapy and the fluid instillation therapy are described. The method may comprise applying negative pressure to the dressing based on an initial therapy configuration, and monitoring negative pressure parameters associated with the application of negative pressure to the dressing to identify negative pressure alarm conditions. The method may further comprise applying instillation fluid to the dressing based on the initial therapy configuration, and monitoring instillation parameters associated with the application of instillation fluid to the dressing to identify instillation alarm conditions. Both may include modifying the initial therapy configuration to generate a modified therapy configuration in response to the negative pressure and instillation alarm conditions identified.

Abstract: A method and apparatus for disrupting material at a tissue site is described. The apparatus includes a modulating layer formed from an open-cell reticulated foam and positionable adjacent the tissue site. The apparatus also includes a macro-column layer formed from a felted foam and having a plurality of through-holes separated from each other by walls. The macro-column layer is positionable adjacent to the modulating layer. The through-holes form nodules in the tissue site in response to negative pressure.

Abstract: A pump generates a vacuum at a wound site via first tubing. A negative pressure circuit is defined by a canister, the first tubing and the wound site. A controller of a therapy device operates the pump to apply a first negative pressure to the entirety of the negative pressure circuit, following which ambient air is allowed to flow into the negative pressure circuit. The controller also operates the pump to apply a second negative pressure to a selected portion of the negative pressure circuit exclusive of the wound site, following which ambient air is allowed to flow into the selected portion. A quantity of fluid to be delivered to the wound site via a second tubing is determined by comparing measured parameters related to the flow of air into the negative pressure circuit to parameters measured with respect to the flow of air into the selected portion.

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.

Abstract: In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Abstract: A device for locking a bone fastening or fixation mechanism in a receiving member of a medical implant. The locking mechanism is kept in place (both in its locked and unlocked positions) using a retaining mechanism. The retaining mechanism also provides predetermined locked and unlocked positions that are readily moved to by the practitioner and maintained in position once placed there.

Abstract: An expandable fusion device capable of being inserted between adjacent vertebrae and expanded laterally to facilitate the fusion process and the use of such device. The expandable fusion device can expand laterally such that it expands the cross-sectional support area of the device to provide more stable support of the support the spine and maintain the normal spacing between opposing vertebrae. The interior area of the expandable fusion device (in which the bone graft can be packed) does not decrease (and generally increases) during expansion of the device. This facilitates pre-packing of the expandable fusion device before utilization.
