Abstract
Expandable devices include a body defining a hollow interior for receiving distal portion of a delivery instrument. The expandable devices are collapsed on the distal portion of the delivery instrument for delivery to the operative site within a vertebral body. Upon delivery of the collapsed expandable devices to the operative site, the distal portion of the delivery instrument is enlargeable to expand the expandable device in situ for implantation at the operative site.

1-67. (canceled)
An intravertebral treatment device comprising:
- a first portion configured for engagement with a vertebra toward a first endplate of the vertebra;
- a second portion configured for engagement with the vertebra toward a second endplate of the vertebra;
- and
- a linkage connecting the first portion and the second portion, the linkage being configured to facilitate relative movement of the first portion and the second portion between a collapsed configuration and an expanded configuration.
An intravertebral treatment device comprising:
- a body including a first portion and a second portion, the first portion defining an engagement surface configured for engagement with a vertebra toward a first endplate of the vertebra, the second portion defining an engagement surface configured for engagement with the vertebra toward a second endplate of the vertebra, the first portion and the second portion defining a cavity therebetween configured for disposal of a filler material;
- a linkage connecting the first portion and the second portion;
- and
- a shaft coupled with the linkage in a configuration to facilitate relative movement of the first portion and the second portion between the collapsed configuration and the expanded configuration in an orientation to provide reduction and stabilization of the vertebra.
A method for treating a vertebral body, the method comprising:
- providing an expandable device comprising a first reduction member, a second reduction member, a linkage coupled between the first reduction member and the second reduction member, and a shaft coupled to the linkage;
- placing the expandable device into the vertebral body;
- rotating the shaft to cause the linkage to move the first reduction member and the second reduction member away from one another.
