Abstract

An implant for filling and / or distracting a body region, particularly a non-soft tissue cavity, has a plurality of segments wherein at least two of the segments are flexibly connected. The segments have a crush-strength sufficient to create and / or maintain the distraction of two or more non-soft tissue body surfaces, and to maintain the stability of the body region. The implant may be inserted into a cavity by an applicator having a cannula with a distal opening, and a rotary driver for applying force to move the implant within the cannula.

Description

FIELD

[0001] Described here are non-soft tissue cavity implants, implant applicators, delivery devices, and methods for using them. In particular, the description relates to implants having a plurality of flexibly connected segments having a strength sufficient to support, to fill, to create, to maintain, or to distract a bone cavity such as might be found in a fractured vertebral body, and methods and devices for inserting implants into non-soft tissue cavities such as bone cavities. BACKGROUND

[0002] Proper treatment of orthopedic conditions such as trauma, fractures, non-unions, tumors, cysts, and certain fusion procedures may involve filling a cavity that has been created by the pathology itself or by the action of a surgeon. Often the cavities are compressed, and require that the surfaces of the cavity be distracted from one another and then supported to return the bone structure to its anatomic position and form. Furthermore, because non-soft tissues such as bone have a struct...
