Abstract
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.

A bone tamp comprising:
- a first shaft;
- a second shaft extending through the first shaft, the first and second shafts defining a channel between the first shaft and the second shaft;
- an inflatable member coupled to the first and second shafts;
- and
- a valve positioned within the channel, the valve being configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the valve does not block the channel.
A bone tamp comprising:
- a first shaft;
- a second shaft extending through the first shaft, the first and second shafts defining a channel between the first shaft and the second shaft;
- an inflatable member coupled to the first and second shafts;
- and
- a valve positioned within the channel, the valve being configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the valve does not block the channel,
- wherein the bone tamp is configured such that when then second shaft is inserted into the first shaft, the second shaft causes the first shaft to move from a straight configuration to a curved configuration.
A bone tamp comprising:
- a first shaft;
- a second shaft extending through the first shaft, the first and second shafts defining a channel between the first shaft and the second shaft, the second shaft comprising opposite first and second ends, the first end comprising a first opening, the second end comprising a second opening, the second shaft defining a lumen, the openings being in communication with the lumen;
- a cap coupled to the second end such that the cap covers the second opening;
- an inflatable member coupled to the first shaft and the cap;
- and
- a valve positioned within the channel, the valve being configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the valve does not block the channel.
