20080269759 | Systems and methods for treating bone using expandable bodies - An expandable device is introduced into a cancellous bone volume of a vertebral body through a percutaneous access path. The vertebral body has at least one cortical plate that is depressed due to fracture. The expandable device is expanded while disposed within the cancellous bone volume. An expansion barrier placed in association with the expandable device directs expansion of the expandable device in a desired direction to move the fractured cortical plate toward a desired anatomic position. | 10-30-2008 |
20080269760 | Apparatus, kits, and methods for creating cavities in cancellous bone using an elongated loop structure or bristles - Systems and method create a cavity in cancellous bone by use of a system or kit that includes a cannula having an axis that establishes a percutaneous path leading into bone and a shaft having a distal end portion carrying an elongated loop structure or bristles capable of extension from the shaft to create a cavity forming structure. The shaft is movable relative to the axis of the cannula to move the cavity forming structure when extended within cancellous bone to form a cavity in the cancellous bone. A tool is sized for passage through the cannula. The tool is capable of dispensing a filling material into the cavity. | 10-30-2008 |
20080269795 | Systems and methods for treating bone using expandable bodies - A vertebral body is selected for treatment. The vertebral body has a cortical wall enclosing a cancellous bone volume. The vertebral body also has at least one cortical plate that is depressed due to fracture. At least one maximum dimension for the cancellous bone volume is ascertained, and an expandable device is provided that has a predefined dimension when substantially expanded that is less than the maximum dimension. The expandable device is introduced into the vertebral body through a percutaneous access path while in an unexpanded condition. The expandable device is expanded while disposed within the cancellous bone volume from the unexpanded configuration toward the expanded configuration. An expansion barrier is provided in association with the expandable device that directs expansion of the expandable device in a desired direction to move the fractured cortical plate toward a desired anatomic position. | 10-30-2008 |
20080269796 | Systems and methods for treating bone using expandable bodies - An expandable device is introduced into a cancellous bone volume of a vertebral body through a percutaneous access path. The expandable device is expanded while disposed within the cancellous bone volume to create a cavity. A volume of filling material is placed within the cavity. The filling material includes a therapeutic substance. | 10-30-2008 |
20090076517 | Systems and methods for treating bone using expandable bodies - A tool served to convey a bone filling material into a cancellous bone volume. The tool carries an expandable structure, which is sized and configured for expansion within the cancellous bone volume to condition the cancellous bone volume for receiving the bone filling material. | 03-19-2009 |
20100168755 | SYSTEMS AND METHODS FOR TREATING FRACTURED OR DISEASED BONE USING EXPANDABLE BODIES - 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. | 07-01-2010 |

20090292289 | Systems and methods for injecting flowable materials into bones - Systems and methods provide greater control over the placement of cement and other flowable liquids into bone. | 11-26-2009 |
20100082036 | SYSTEMS AND METHODS FOR TREATING FRACTURED OR DISEASED BONE USING EXPANDABLE BODIES - 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. | 04-01-2010 |
20100160923 | SYSTEMS AND METHODS FOR INJECTING FLOWABLE MATERIALS INTO BONES - A cavity creation device is introduced into a cancellous bone volume of a vertebral body through a percutaneous access path. The cavity creating device is manipulated to form a cavity in the cancellous bone volume. A volume of filling material is placed in the cavity by introducing a tube through the percutaneous access path and by conveying the filling material through a side dispensing port of the tube. | 06-24-2010 |
20110144688 | DEVICES AND METHODS USING AN EXPANDABLE BODY WITH INTERNAL RESTRAINT FOR COMPRESSING CANCELLOUS BONE - Devices and methods compress cancellous bone. In one arrangement, the devices and methods make use of an expandable body that includes an internal restraint coupled to the body. The internal restraint directs expansion of the body. In one arrangement, a method for treating bone inserts the device having the internal restraint inside bone and causes directed expansion of the body in cancellous bone. Cancellous bone is compacted by the directed expansion. | 06-16-2011 |
