摘要
An inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft defines a lumen. A balloon has a first end coupled to the outer shaft and a second end coupled to the inner shaft such that material can flow through the lumen and into the balloon and exit the balloon through a channel between the inner and outer shafts. A valve is positioned within the channel. The valve is configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the does not block the channel. Kits, systems and methods are disclosed.
