A first lumen extends along the longitudinal axis of the catheter and defines a first passageway. A second lumen extends along the longitudinal axis of the catheter and defines a second passageway. An inflatable body includes a wall that defines a fillable cavity. The fillable cavity is in fluid communication with the first passageway. A bone filler delivery port continuous with the second passageway and configured to dispense bone filling material. ## Claims ### Claim 1 A bone filling device comprising: a catheter defining a longitudinal axis extending between a proximal end and a distal end; a first lumen extending along the longitudinal axis of the catheter defining a first passageway; a second lumen extending along the longitudinal axis of the catheter defining a second passageway; an inflatable body having a wall configured to define a fillable cavity, wherein the fillable cavity is in fluid communication with the first passageway; and a bone filler delivery port continuous with the second passageway and configured to dispense bone filling material, wherein the device is configured for insertion through a cannula into tissue. ### Claim 2 (depends on 1) A bone filling device as recited in claim 1 further comprising a bone filler tube configured for insertion into the second lumen so as to exit the bone filler delivery port to dispense bone filling material. ### Claim 3 (depends on 1) A bone filling device as recited in claim 1, wherein the inflatable body is disposed at the distal end of the catheter. ### Claim 4 (depends on 1) A bone filling device as recited in claim 1, wherein the first lumen is spaced apart from the second lumen. ### Claim 5 (depends on 1) A bone filling device as recited in claim 1, wherein the first lumen terminates prior to the distal end of the catheter and the second lumen opens external to the fillable cavity. ### Claim 6 (depends on 1) A bone filling device as recited in claim 1, wherein the first lumen is configured to inflate the inflatable body. ### Claim 7 (depends on 1) A bone filling device as recited in claim 1, wherein the inflatable body is asymmetric about the longitudinal axis. ### Claim 8 (depends on 1) A bone filling device as recited in claim 1, wherein the inflatable body is a balloon and is coupled to the catheter at a first point and at a second point spaced apart from the first point. ### Claim 9 (depends on 1) A bone filling device as recited in claim 1, wherein the inflatable body is configured to inflate and apply a force capable of compacting cancellous bone and moving fractured bone. ### Claim 10 (depends on 1) A bone filling device as recited in claim 1, wherein the inflatable body comprises radio opaque markers to determine orientation of the inflatable body in situ. ### Claim 11 A bone filling system comprising: a cannula; a bone filling device including a catheter defining a longitudinal axis extending between a proximal end and a distal end; a first lumen extending along the longitudinal axis of the catheter defining a first passageway; a second lumen extending along the longitudinal axis of the catheter and defining a second passageway; a balloon having a wall configured to define a fillable cavity, wherein the fillable cavity is in fluid communication with the first passageway; and a bone filler delivery port continuous with the second passageway and configured to dispense bone filling material, wherein the device is configured for insertion through the cannula into tissue such that the inflatable body is configured to inflate and apply a force capable of compacting cancellous bone and moving fractured bone to restore height to the bone. ### Claim 12 (depends on 10) A bone filling device as recited in claim 10, wherein the balloon is disposed at the distal end of the catheter. ### Claim 13 (depends on 10) A bone filling system as recited in claim 10, wherein the first lumen is spaced apart from the second lumen. ### Claim 14 (depends on 10) A bone filling system as recited in claim 10, wherein the first lumen terminates prior to the distal end of the catheter. ### Claim 15 (depends on 10) A bone filling system as recited in claim 10, wherein the first lumen is configured to inflate the balloon. ### Claim 16 (depends on 10) A bone filling system as recited in claim 10, wherein the balloon is asymmetric about the longitudinal axis. ### Claim 17 (depends on 10) A bone filling system as recited in claim 10, wherein the balloon is coupled to the catheter at a first point and at a second point spaced apart from the first point. ### Claim 18 (depends on 10) A bone filling system as recited in claim 10, wherein the inflatable body comprises radio opaque markers to determine orientation of the inflatable body in situ. ### Claim 19 A method of filling bone comprising: inserting a cannula into bone; inserting a catheter through the cannula, the catheter defining a longitudinal axis extending between a proximal end and a distal end and includes; a first lumen extending along the longitudinal axis of the catheter defining a first passageway; a second lumen extending along the longitudinal axis of the catheter and defining a second passageway; a balloon having a wall configured to define a fillable cavity, wherein the fillable cavity is in fluid communication with the first passageway; and a bone filler delivery port continuous with the second passageway and configured to dispense bone filling material; inflating the balloon such that the balloon applies a force capable of compacting cancellous bone and moving fractured bone; inserting a bone filler through the passageway and delivering a bolus of bone filler material while the balloon is inflated; allowing for the bone filler material to cure such it forms a shell of bone filler material around the balloon and is capable of maintaining a restored height to the bone; and deflating and removing the balloon. ### Claim 20 (depends on 19) A method of filling bone as recited in claim 19, further including the step of filling the bone with additional bone filling material after the balloon is removed.
