The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.

A system to be used for transmitting ultrasonic vibration, the system including a sonotrode designed to vibrate in a stationary wave having at least one node position between the distal end and the proximal end of the sonotrode, and a guide shaft with a through opening. During operation the sonotrode extends through the through opening of the guide shaft and the distal end of the guide shaft is situated on a distal side of the most distal node position of the sonotrode. The sonotrode and the guide shaft are adapted to each other for radial clearance between the sonotrode and the guide shaft to be a minimum for a sonotrode portion comprising the most distal node position.

A continuous compression fixation device for coupling a first bony structure to a second bony structure, including: a body structure; and a plurality of arm structures extending from the body structure, wherein at least one of the plurality of arm structures is configured to be coupled to the first bony structure and at least one opposed one of the plurality of arm structures is configured to be coupled to the second bony structure; wherein the body structure and the plurality of arm structures are manufactured from a shape memory material; and wherein tips of the at least one of the plurality of arm structures and the at least one opposed one of the plurality of arm structures are biased towards one another such that a desired compressive force is applied to an intercalary structural augment disposed between the first bony structure and the second bony structure.

A medical compound preparation and delivery system, including a delivery device, the device including a depressible trigger operably coupled to move a plunger; a cartridge releasably coupled to the delivery device, the cartridge defining a lumen therethrough to receive at least a portion of the plunger therein; a receptacle defining a cavity therein for receiving a medical compound; a first tube slidably positionable within the cavity of the receptacle; and a second tube slidably positionable within the first tube, wherein the cartridge is slidably positionable within the second tube.

An apparatus for mixing bone cement can comprise a receiving chamber, a mixing chamber, a cannula, a base, and a piston located within the mixing chamber. The receiving chamber defining a conduit. The mixing chamber in fluid communication with the receiving chamber. The mixing chamber configured to house a first component of the bone cement. The cannula located in the receiving chamber and in fluid communication with the conduit. The base including a bladder arranged to be punctured by the cannula, the bladder configured to house a second component of the bone cement. Upon puncturing of the bladder by the cannula the second component of the bone cement passes through the conduit and the cannula into the mixing chamber. The piston configured to seal the mixing chamber upon movement of the piston from a first position relative to the conduit to a second position relative to the conduit.

The bone cement injection device includes an injection assembly and a filler assembly. The injection assembly includes a barrel, first needle member, second needle member, and plunger. The first needle member is movably housed inside the barrel, and includes a first member body, a first conduit, a side tube, and puller elements. The second needle member is housed in the first needle member, and includes a second member body, and a second conduit. A space is maintained between the first and second conduits. The plunger is joined to the first member body and is movably housed in the second member body. The filler assembly fills bone cement into the second member body. The first needle member is pulled backward, and the plunger injects the bone cement into the patient's bone. With an air compressor connected to the side tube, a negative pressure is created to facilitate bone cement injection.

A device for hydrating particulate bone material is provided. The device comprises a tubular member having an interior surface and an exterior surface. The interior surface is configured to receive the particulate bone material and a hydration fluid. The exterior surface has a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material. The plurality of pores are smaller in size than the particulate bone material. Methods of dispensing particulate the bone material are also provided.

A method for treating arthritis of a joint includes identifying a bone lesion in a bone adjacent to the joint; and implanting in the bone a reinforcing member in or adjacent to the bone lesion. A kit for conducting the method includes: (a) at least one reinforcing member having a proximal face adapted to face the joint, a distal face adapted to face away from the joint, and a wedge-shaped edge adapted to pierce bone, wherein the at least one reinforcing member is planar and sterile; and (b) a container adapted to maintain the at least one reinforcing member sterile. Another kit includes: (a) a sterile fluid; (b) a syringe for injecting the fluid into a bone; (c) a curing agent adapted to cure the fluid to polymerize and/or cross-link; and (d) a container adapted to maintain the sterility of contents of the container.

A syringe mixing device has a cylindrical syringe housing, an end cap, a nozzle cap, a removable stir rod mixer assembly, a large mouth funnel, and optional locking clip. The cylindrical syringe housing has an internal chamber for holding material, a distal end and a proximal end. Adjacent the proximal end is a pair of finger grips. The end cap has a proximal end for attaching to the distal end of the syringe housing. The end cap has a nozzle configured to pass material ejected from the syringe housing. The nozzle cap is for sealing the nozzle. The large mouth funnel is configured to fasten at a throat end to the distal end of the cylindrical syringe housing. The funnel has a slope shaped chamber configured to receive and pass material for mixing into the internal chamber of the syringe housing. The syringe mixing device further has a removable plunger.

An implant filling apparatus may include an actuator mechanism, a push rod, straight fill tubes and/or diverted tip fill tubes and an implant connector. An actuator impacts the push rod at a predetermined pressure and rate such that the push rod can drives fill material out of the fill tube(s) and into an implant that is coupled to the implant connector.
