Embodiment Construction

[0043] The systems and methods embodying the invention can be adapted for use virtually in any interior body region, where the formation of a cavity within tissue is required for a therapeutic or diagnostic purpose. The preferred embodiments show the invention in association with systems and methods used to treat bones. This is because the systems and methods which embody the invention are well suited for use in this environment. It should be appreciated that the systems and methods which embody features of the invention can be used in other interior body regions, as well.

Abstract

A shaft having an axis and a distal end portion is adapted to be deployed inside a vertebral body through a cannula. A filament is carried by the distal end portion. A surface on the filament is movable between a collapsed condition sized and configured to be deployed with the shaft through the cannula and an extended position that extends radially from the shaft. A mechanism is coupled to the filament to extend the filament in situ radially from the shaft into contact with cancellous bone within the vertebral body. The surface, when extended, defines a structure capable of forming a cavity wholly within the vertebral body in the cancellous bone.

Description

RELATED APPLICATIONS [0001] This application is a divisional of application Ser. No. 10 / 208,391, filed Jul. 30, 2002 and entitled “Structures and Methods for Creating Cavities in Interior Body Regions,” which is a divisional of application Ser. No. 09 / 055,805, filed Apr. 6, 1998 (now U.S. Pat. No. 6,440,138).FIELD OF THE INVENTION [0002] The invention relates to structures and procedures, which, in use, form cavities in interior body regions of humans and other animals for diagnostic or therapeutic purposes. BACKGROUND OF THE INVENTION [0003] Certain diagnostic or therapeutic procedures require the formation of a cavity in an interior body region. [0004] For example, as disclosed in U.S. Pat. Nos. 4,969,888 and 5,108,404, an expandable body is deployed to form a cavity in cancellous bone tissue, as part of a therapeutic procedure that fixes fractures or other abnormal bone conditions, both osteoporotic and non-osteoporotic in origin. The expandable body compresses the cancellous bon...
