Abstract: The apparatus for production of mixtures from two components has a container for each and devices to combine the components in the mixing space and for extrusion of the mixture. The powdered component (4) is situated in the lower part of the inner space (21), which is sealed by a bottom (10). This carries a nozzle (2) with closure membrane (3). The inner space (21) is closed on the top by the lower wall (6) and the sliding seal (8). The liquid component (9) is situated in the inner space (18) of the inner hollow cylinder (5). This is closed on the top by the upper wall (11). The lower and upper wall (6) and (11) each have an opening with sealing lips (7) and (12) that are closed by parts of the mixing rod (15). A torus (20), a section with smaller diameter (19), a mixing disk (22), as well as a mandrel (24), are present on the lower part of the mixing rod (15).
Abstract: A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone). The balloon comprises an inflatable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and/or to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon desirably incorporates restraints which inhibit the balloon from applying excessive pressure to various regions of the cortical bone. The wall or walls of the balloon are such that proper inflation of the balloon body is achieved to provide for optimum compression of the bone marrow. The balloon can be inserted quickly into a bone. The balloon can be made to have a suction catheter. The balloon can be used to form and/or enlarge a cavity or passage in a bone, especially in, but not limited to, vertebral bodies.

Abstract: A tube body includes an interior bore to carry a material flow into bone. The tube body includes a dispensing end having an opening communicating with the bore to dispense the material flow. One embodiment provides a cutting element, 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. Another embodiment deflects the dispensing end from the main axis of the tube body, to facilitate targeted introduction of flowable material, even when the access path does not align the tube body along the natural geometric axes of the treatment site. Another embodiment provides a connector having a rotating fitting, which releasably connects the tube body to a cement injecting tool. The rotating fitting allows the physician to rotate the injection nozzle assembly to control orientation and position in the treatment site, without rotating the associated injection tool itself.

Abstract: 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, concurrently.

Abstract: A filler instrument comprises a first chamber section having a first cross sectional area and a second chamber section having a second cross sectional area less than the first cross sectional area. The second chamber section communicates with the first chamber section. The first chamber section includes an inlet for receiving a material into the filler instrument, and the second chamber section includes an outlet for discharging the material from the filler instrument. A first plunger is sized to pass through the first chamber section and not the second chamber section. A second plunger is sized to pass through an interior bore of the first plunger and into the second chamber section. In use, the first plunger displaces material residing in the first chamber section through the second chamber section toward the outlet, and the second plunger displaces material residing in the second chamber section through the outlet.

Abstract: This invention relates to a cement, which consists in its main phase of microcrystalline magnesium ammonium phosphate and nanoapatite after hardening and thus at the same time has considerable strength.
The material is biologically degradable and is suitable for application in tooth cements, as bone replacement, as bone filler, as bone cement or as bone adhesive.
Abstract: A tool for deploying an expandable structure into interior body regions provides a catheter body having an interior lumen. The catheter body carries an expandable structure. A stylet is sized configured for passage through the lumen and adapted to straighten the expandable structure during deployment into an interior body region.

Abstract: Systems and methods for delivering material into bone deploy a cannula through soft tissue to establish a subcutaneous path into bone. A material is introduced into bone through the cannula. The systems and methods advance a tamping instrument through the cannula to urge material residing in the cannula into bone. The introducing step delivers material at a pressure no greater than about 360 psi.

Abstract: A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone) against the inner cortex of bones whether the bones are fractured or not. The balloon comprises an inflatable, non-expandable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon is prevented from applying excessive pressure to the outer cortical bone. The wall or walls of the balloon are such that proper inflation the balloon body is achieved to provide for optimum compression of all the bone marrow. The balloon is able to be folded so that it can be inserted quickly into a bone. The balloon can be made to have a suction catheter. The main purpose of the balloon is the forming or enlarging of a cavity or passage in a bone, especially in, but not limited to, vertebral bodies.
