Abstract
An inflatable bone tamp including a first balloon portion and a second balloon portion is provided. Each of the first balloon portion and the second balloon portion include interior cavities that can be filled with liquid, and these interior cavities communicate with one another via a valve. The valve can limit or restrict flow of the liquid between the cavities. As such, the first balloon portion and the second balloon portion can be sequentially inflated with the liquid through use of the valve.

An inflatable bone tamp comprising:
- an inner first tubular portion including a first passageway therethrough, and extending between a first proximal end and an opposite first distal end, the inner first tubular portion including at least one aperture adjacent the first distal end;
- an outer second tubular portion including a second passageway therethrough, and extending between a second proximal end and an opposite second distal end, the inner first tubular portion extending through the second passageway;
- a valve including an outer surface, a first side, an opposite second side, an aperture extending between the first side and the second side, and various perforations extending between the first side and the second side, the inner first tubular portion being received through the aperture;
- a first balloon portion including a first cavity, a first distal end portion, and a first proximal end portion, the first distal end portion being attached relative to the inner first tubular portion, and the first proximal end portion being attached relative to the outer surface of the valve;
- and
- a second balloon portion including a second cavity, a second distal end portion, and a second proximal end portion, the second distal end portion being attached relative to the outer surface of the valve, and the second proximal end portion being attached relative to the outer second tubular portion;
- wherein the first cavity and the second cavity communicate with one another via the various perforations in the valve,
- wherein a liquid pumped through the first passageway can enter the first cavity via the at least one aperture of the inner first tubular portion and can expand the first balloon portion from a first contracted position to a first expanded position,
- wherein the valve limits passage of the liquid from the first cavity to the second cavity through the various perforations until a threshold pressure of the liquid is reached in the first cavity, and
- wherein the fluid entering the second cavity via the various perforations in the valve can expand the second balloon portion from a second contracted position to a second expanded position.
