Transverse cavity device and method
First Claim
Patent Images
1. A method of treating a compression fracture in a bone, comprising the steps of:
- forming a transverse cavity within said bone defined by at least one substantially flat surface lying substantially in a transverse plane formed by and communicating with said transverse cavity, said transverse cavity having a substantially uniform transverse extent and a maximum height, said maximum height being less than said transverse extent; and
applying a force within said transverse cavity generally normal to said surface to displace said surface and restore said bone to its substantially normal anatomic position.

Abstract
A method for treating a compression fracture in a bone includes the step of forming a transverse cavity and then applying a force within the cavity generally normal to a surface of the bone to restore it substantially to its normal anatomic shape. In certain embodiments, the force is applied by an expandable device.

12. A method of treating a compression fracture in a vertebral body of the spine to substantially restore normal vertebral body height, comprising the steps of:
-
forming within said vertebral body a transverse cavity defined by at least one substantially flat surface lying in a transverse plane extending substantially normal to the axis of the spine, said transverse cavity having a substantially uniform transverse extent and a substantially uniform height across said transverse extent, said height being less that said transverse extent; introducing an expandable device into said transverse cavity in an unexpanded condition; deploying said expandable device to substantially occupy said transverse cavity; and expanding said expandable device against said surface to cause said surface to move generally along said axis of the spine to thereby restore the vertebral body height to its substantially normal anatomic height. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
