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.

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. Show less

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. Show less

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.
