摘要:
A method and apparatus for filling a cavity in a patient's body with a material are provided. The apparatus can include a flexible tube, a barrel and a plunger. The flexible tube has a first end, a second end, and a lumen extending from the first end to the second end and operable to hold a material for conveyance through the first end into a cavity. The barrel is in fluid communication with the second end of the flexible tube and includes a lumen configured to receive material for delivery into the flexible tube. The plunger is configured to advance material through the lumen in the barrel and into the flexible tube. In one implementation, there is substantially a one to one ratio of advancement of the plunger to a volume of material advanced from the rigid first end of the flexible tube.

Systems and methods treat at least two vertebral bodies in a spinal column. The systems and methods make use of first and second tool assemblies operable to treat an interior region of, respectively, a first vertebral body and a second vertebral body in the spinal column. The systems and methods provide directions for operating the first and second tool assemblies to treat the first and second vertebral bodies, at least for a portion of time.

摘要:
This invention is systems (10), and methods for delivering material into bone to deploy a cannula (30) through soft tissue to establish a subcutaneous path into bone. A material is introduced through the cannula (30). The system (10), and methods advance a tamping instrument (108) through the cannula (30) to urge material residing in the cannula into bone. The introducing step delivers material at a pressure no greater than about 360 psi.

摘要:
A composite instrument (10) is provided comprising a first functional instrument (20) and a second functional instrument (40) when the first functional instrument (20) is coupled with the second functional instrument (40). A composite handle (12) for the composite instrument is provided comprising a first handle (22) and a second handle (42) when the first handle (22) is coupled with the second handle (42). The handle (12) makes possible the reliable transmission, with increased mechanical advantage, of both torsional and longitudinal loads by the physician to the composite instrument, while resisting relative rotation between the first and second instruments (20, 40). The instrument is sterilization sensitive, changing physical appearance after sterilization.
摘要:
A tube body (30) includes an interior bore to carry a material flow into bone. The tube body (30) includes a dispensing end (32) having an opening (64) communicating with the bore to dispense the material flow. One embodiment provides a cutting element (100) which extends in the opening to permit passage of the material flow, and to sever the material flow in response to rotation of the tube body (30). Another embodiment deflects the dispensing end from the main axis of the tube body. Another embodiment provides a connector having a rotating fitting, which releasably connects the tube body (30) to a cement injecting tool.
摘要:
Systems treat fractured or diseased bone by deploying therapeutic tools into the bone. The systems deploy at least one expandable body (56) into the bone. Expansion of the body or bodies forms one or more cavities in cancellous bone in the interior bone volume (30).
