A curved inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft extends between opposite first and second end. The inner shaft defines a lumen. The inner shaft is curved between the first end and the second end. A first leg of a balloon is coupled to the outer shaft and a second leg of the balloon is coupled to the inner shaft such that a material can flow through the lumen and into the balloon to inflate the balloon. The balloon includes a wall having a variable thickness between the legs when the balloon is uninflated and a uniform thickness between the legs when the balloon is inflated. Kits, systems and methods are disclosed.

A mould adapted to be introduced into a joint of a human patient for resurfacing at least one carrying contacting surface of said joint is provided. The mould is adapted to receive material for resurfacing at least one carrying contacting surface of said joint. The mould is further adapted to be resorbed by the human body or melt after having served its purpose.

A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

The invention relates to a cement director for insertion within a vertebral body or other body structure, and related methods of use. An example method includes creating a cavity in a vertebral body, inserting a collapsible mesh structure into the cavity in a collapsed state, wherein the collapsible mesh structure comprises regions of different permeability to a bone cement, inflating a balloon within the collapsible mesh structure to expand the mesh structure, and injecting a bone cement into the mesh structure, wherein the bone cement flows preferentially out of the mesh structure through at least one region of greater permeability.

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.

A method of using a robotic guidance system for performing surgery on a spine is provided. The method includes utilizing a computerized tomographic scan image of a location on a spinal column of a patient, such that the computerized tomographic scan image is connected to a computer and visible on a monitor connected to the computer. The method also includes attaching a coupling component to the spinal column of the patient, coupling a marker to the coupling component, and imaging, with a fluoroscope, the view of the spinal column of the patient, wherein the fluoroscope image is transmitted to the computer and visible on the monitor and the at marker is clearly visible in the fluoroscope image. The method also includes positioning a cannula, with a robotic mechanism, to a first position relative to a vertebra in the spinal column of the patient, drilling a passage through the cannula into bone of the vertebra in the spinal column of the patient, inserting a guidewire through the cannula into the passage in the bone of the vertebra in the spinal column of the patient, and positioning a screw into the bone of the vertebra in the spinal column of the patient.

The present disclosure relates to systems and methods for mixing and injecting fluid treatment, such as cement to treat bone or hard tissue. In some embodiments, a mixing apparatus may facilitate mixing within a syringe. Additionally, the syringe may be configured to extract bone cement from a cement mixer. A syringe for mixing and injecting cement may include a detachable handle that may be detached after extracting bone cement from a mixer to facilitate coupling to a high-pressure syringe for injection.

Methods of filling bone cavities are provided. The methods use a bone cement mixing and delivery device that includes a shaft extending along an axis from a first end to a second end and including a passageway. The first end includes an adapter having a first opening that is in communication with the passageway. The second end includes a second opening that is in communication with the passageway. The shaft includes a mixing portion between the first and second ends. A connector includes a central portion that that is coupled to the adapter. The central portion includes a channel that is in communication with the first opening. The connector includes first and second ports that extend from the central portion. The first port includes a first lumen that is in communication with the channel. The second port includes a second lumen that is in communication with the channel.
