Abstract
A bone filling device includes a catheter that defines a longitudinal axis and extends between a proximal end and a distal end. 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.
Claims20
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.
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.
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.
