Problems solved by technology

When cancellous bone becomes diseased, for example, because of osteoporosis, avascular necrosis, or cancer, the surrounding cortical bone becomes more prone to compression fracture or collapse.
This is because the cancellous bone no longer provides interior support for the surrounding cortical bone.
These conditions, if not successfully treated, can result in deformities, chronic complications, and an overall adverse impact upon the quality of life.

Embodiment Construction

[0074] This Specification describes new systems and methods to treat bones using expandable bodies. The use of expandable bodies to treat bones is disclosed in U.S. Pat. Nos. 4,969,888 and 5,108,404, which are incorporated herein by reference. Improvements in this regard are disclosed in U.S. patent application Ser. No. 08 / 188,224, filed Jan. 26, 1994; U.S. patent application Ser. No. 08 / 485,394, filed Jun. 7, 1995; and U.S. patent application Ser. No. 08 / 659,678, filed Jun. 5, 1996, which are each incorporated herein by reference.

[0075] The new systems and methods will be first described with regard to the treatment of vertebra. It should be appreciated, however, the systems and methods so described are not limited in their application to vertebrae. As will be described in greater detail later, the systems and methods are applicable to the treatment of diverse bone types.

Abstract

Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time. In another arrangement, the systems and methods deploy multiple expandable bodies, which occupy the bone interior volume simultaneously. Expansion of the bodies form cavity or cavities in cancellous bone in the interior bone volume.

Description

RELATED APPLICATIONS [0001] This application is a divisional of co-pending U.S. patent application Ser. No. 09 / 754,451 filed 4 Jan. 2001, which is a continuation of U.S. patent application Ser. No. 08 / 871,114 filed 9 Jun. 1997, which is a continuation-in-part of U.S. patent application Ser. No. 08 / 659,678, filed Jun. 5, 1996, which is a continuation-in-part of U.S. patent application Ser. No. 08 / 485,394, filed Jun. 7, 1995, which is a continuation-in-part of U.S. patent application Ser. No. 08 / 188,224, filed Jan. 26, 1994 entitled, “Improved Inflatable Device For Use In Surgical Protocol Relating To Fixation Of Bone.”FIELD OF THE INVENTION [0002] The invention relates to the treatment of bone conditions in humans and other animals. BACKGROUND OF THE INVENTION [0003] When cancellous bone becomes diseased, for example, because of osteoporosis, avascular necrosis, or cancer, the surrounding cortical bone becomes more prone to compression fracture or collapse. This is because the cancel...
