A mixing and delivery system includes a compressible tube and a mixing apparatus. The compressible tube includes a reservoir configured for mixing and holding a surgical substance, an inlet portion for accommodating introduction of an element of the surgical substance into the compressible tube, and an exit port for enabling the delivery of the surgical substance to a target portion of an anatomy. The mixing apparatus is configured to be received through the inlet portion of the compressible tube for mixing elements of the surgical substance to form the surgical substance.

A needle-mounted balloon system can include a cannula and a stylet. The cannula may include a handle and an outer sheath, and the outer sheath may be configured to retract and expose at least a portion of an expandable member. The stylet may include a stylet needle and a sharp distal tip portion. The stylet needle may be used to insert the system into a body structure, after which the stylet may be disengaged from the cannula. The expandable member may then be exposed and inflated to create a space in the body structure. Filler material may be injected through the cannula to the open space in an effort to stabilize an injured or otherwise destabilized portion of the body structure.

A system including a flow diverter for delivering bone cement. A cannula coupler is coupled to the flow diverter and configured to be coupled to a delivery cannula. A drool accumulator is coupled to the flow diverter. A user input mechanism is coupled to the flow diverter and configured to actuate a valve and establish fluid communication between the cement reservoir and one of the cannula coupler and the drool accumulator. The fluid communication may be interrupted between the cement reservoir and the other one of the cannula coupler and the drool accumulator. A cement delivery input mechanism may be coupled to the cement reservoir and configured to be actuated to direct the bone cement from the cement reservoir towards the flow diverter. An actuator may be coupled to the drool accumulator and configured to direct the bone cement received in the drool volume towards the flow diverter.

The present invention is generally directed to orthopedic fixation devices that comprise a pre-assembled double headed tulip assembly, having two tulip elements to receive rods, wherein the assembly may be configured to receive a bone fastener in at least one of the tulip elements. At least one of the tulip elements may comprise a saddle and a ring to attach the double headed tulip to a bone fastener.

In order to deliver porous particulate material into a cavity via a thin tube without substantially crushing the porous particulate material, a two-step process and an apparatus for use therein are provided. The two-step process involves inserting a first rod into the thin tube to push the porous particulate material therein; removing the first rod from the tube; and (a) inserting a second rod into the thin tube, or (b) joining a second rod with the first rod, and inserting the joined first rod and second rod, to push the porous particulate material which remains in the thin tube. In (a), the first rod has a cross sectional area significantly smaller than that of the thin tube, and the second rod has a cross sectional area which is about equal to that of the thin tube. In (b), each of the first rod and the second rod has a cross sectional area about half of the thin tube.

A method of stabilizing a first vertebra and a second vertebra includes implanting a first bone anchor into the first vertebra, implanting a second bone anchor into the second vertebra, connecting a first anchor connection instrument to the first anchor, connecting a second anchor connection instrument the second anchor, positioning a cement delivery tube into a passage provided through the first anchor, delivering bone cement from a bone cement delivery system coupled to the bone cement delivery tube through the passage in the first anchor to the first vertebra, removing the cement delivery tube from the first anchor connection instrument and the first anchor, connecting the cement delivery tube to second anchor connecting instrument connected to the second anchor, delivering bone cement through a passage in the second anchor to the second vertebra, connecting a spinal connection element to the first anchor and the second anchor.

The invention relates to a delivery system, device and method for delivering biomaterials for fracture fixation (including augmented fixation), in particular, for delivery of bone cements. The mixing system ensures the biomaterial only commences setting upon extrusion from the mixer, cannula or during injection through an appropriate internal fracture fixation device, allowing for rapid closing by the surgeon. The system also permits the surgeon to cease injecting the cement for an extended period of time before continuing the injection in another area using the same cartridge, through the simple removal of one mixer and attaching another in its place. The invention also provides a method of delivery of biomaterials to a desired implantation site.

A device for dispensing a bone cement from a container, comprising a connecting element for reversibly connecting the device to the container, a rod-like dispensing element, which at least partially has an external thread, a switching system, which at least partially has a first internal thread, wherein the first internal thread can be coupled in a positive manner to the external thread in such a way that the dispensing element can be axially screwed into the container in a first coupled switching system position, and the dispensing element can be pushed freely axially into the container in a second decoupled switching system position.

A balloon, a medical device, and a medical procedure for discoplasty are disclosed. The balloon has a compressed, collapsed or folded balloon body containing a first chamber for, in use, receiving injected bone cement. With the bone cement filled and cured therein, the balloon acts as a support in tissue of an intervertebral disc while preventing the bone cement from leakage and dispersion. The deployed balloon body defines a second chamber running therethrough. The second chamber is configured to receive a material or cells that activate osteogenesis and/or osteo-induction, so that the material or cells injected into the second chamber through a second sprue form osteocytes or induce human spontaneous local cellular differentiation to in turn form osteocytes in the cavity of the intervertebral disc and connect vertebrae above and below the intervertebral disc, thereby securely anchoring the balloon within the intervertebral space.

An integrated targeted kyphoplasty system includes a piercing head, a tube body and a tube body handle. The tube body has an end connected to the piercing head and is provided with a balloon and a guider at an end of the balloon, and another end connected to the tube body handle and provided with a guide knob for controlling the guider to be bent and a pressure pump connector communicating the balloon. The piercing head is provided with a cement outlet, a cement channel is in center of the tube body, and the tube body handle is provided with a cement inlet. The cement outlet, cement channel and cement inlet communicate with each other. The device requires for only one piercing to complete entire KP surgical treatment without changing any tools, greatly decreasing radiation exposure rate of the patient during operation and the pain caused by multiple operations.
