Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
A method for treating bone comprising the steps of selecting a body comprising an expandable wall, selecting a nozzle for discharging a material, inserting both the body and the nozzle through an access path in cortical bone into an interior bone volume occupied, at least in part, by cancellous bone, locating the nozzle in the interior bone volume distally of the body such that the body lays between the nozzle and the access path, causing the body to assume an expanded geometry while occupying the interior volume in the presence of the nozzle to compact cancellous bone and form a cavity in the interior volume, and conveying a material for discharge through the nozzle into the cavity distally of the body at least partially while the body occupies the interior volume.
Claim 2
Independent Claim
131 words
A method for treating bone comprising the steps of selecting a body comprising an expandable wall, selecting a nozzle for discharging a material, inserting both the body and the nozzle through an access path in cortical bone into an interior bone volume occupied, at least in part, by cancellous bone, locating the nozzle in the interior bone volume distally of the body such that the body lays between the nozzle and the access path, causing the body to assume an expanded geometry while occupying the interior volume in the presence of the nozzle to compact cancellous bone and form a cavity in the interior volume, and conveying a material for discharge through the nozzle into the cavity distally of the body at least partially while the body occupies the interior volume.
Claim 3
Dependent Claim
19 words
A method according to claim 1 wherein the conveying step includes conveying bone cement for discharge through the nozzle.
Claim 4
Independent Claim
126 words
A method for compacting cancellous bone comprising the steps of selecting a first catheter tube carrying a first body comprising an expandable wall, selecting a second catheter separate from that the first catheter tube and carrying a second body comprising an expandable wall, manipulating the first catheter tube to insert the first expandable body into bone through a first access path through cortical bone, and manipulating the second catheter tube to insert the second expandable body into the bone through a second access path through cortical bone different than the first access path, and causing at least one of the first and second expandable bodies to assume an expanded geometry while occupying the bone, to compact cancellous bone about the expandable body to form a cavity.
Claim 5
Independent Claim
126 words
A method for compacting cancellous bone comprising the steps of selecting a first catheter tube carrying a first body comprising an expandable wall, selecting a second catheter separate from that the first catheter tube and carrying a second body comprising an expandable wall, manipulating the first catheter tube to insert the first expandable body into bone through a first access path through cortical bone, and manipulating the second catheter tube to insert the second expandable body into the bone through a second access path through cortical bone different than the first access path, and causing at least one of the first and second expandable bodies to assume an expanded geometry while occupying the bone, to compact cancellous bone about the expandable body to form a cavity.
Claim 6
Independent Claim
90 words
A method for compacting cancellous bone comprising the steps of inserting an expandable body having first and second expandable zones into an interior bone volume, expanding the first expandable zone to form a barrier within the interior bone volume while leaving a region of substantially uncompacted cancellous bone extending from the barrier within the interior bone volume, and expanding the second expandable zone in the region to compact cancellous bone and form a cavity in the region while the barrier directs expansion of the second expandable zone into the region.
Claim 7
Independent Claim
90 words
A method for compacting cancellous bone comprising the steps of inserting an expandable body having first and second expandable zones into an interior bone volume, expanding the first expandable zone to form a barrier within the interior bone volume while leaving a region of substantially uncompacted cancellous bone extending from the barrier within the interior bone volume, and expanding the second expandable zone in the region to compact cancellous bone and form a cavity in the region while the barrier directs expansion of the second expandable zone into the region.
Claim 8
Dependent Claim
17 words
A method according to claim 3 further including the step of filling the cavity with a material.
Claim 9
Dependent Claim
12 words
A method according to claim 5 wherein the material comprises bone cement.
Claim 10
Dependent Claim
13 words
A method according to claim 5 wherein the material comprises synthetic bone substitute.
Claim 11
Dependent Claim
19 words
A method according to claim 5 wherein the material comprises a flowable material that sets to a hardened condition.
Claim 12
Dependent Claim
23 words

Claim 14
Dependent Claim
17 words
A method according to claim 9 wherein the first and second expandable bodies assume expanded geometries sequentially.
