One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste, the device having a cartridge having a cylindrical interior. The interior of the cartridge is closed on the front side except for a delivery opening for expelling the bone cement paste. A delivery plunger is arranged in the interior of the cartridge. The cement powder is arranged in the interior of the cartridge. A closure is arranged on the front side of the delivery plunger. The closure closes the delivery opening when the delivery plunger is pressed against the front side of the interior of the cartridge. The closure blocks a further movement of the delivery plunger so that the delivery plunger is spaced from the front side of the interior of the cartridge at least in some areas and a dead volume remains in the interior of the cartridge when the delivery plunger is pressed against the front side of the interior of the cartridge.

A device for dispensing biomaterial includes a handle configured to receive a syringe, the syringe including a biomaterial and a threaded plunger, and an engagement pin retained within the handle and slidable between a first position and a second position. The engagement pin is configured to engage the threaded plunger in the first position, the engagement pin is further configured to disengage from the threaded plunger in the second position.

A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

A device for storage of a monomer liquid and a cement powder as starting components of a bone cement dough and for mixing the starting components, and for dispensing the mixed bone cement dough. The device includes a receptacle in which a monomer liquid container is arranged and a cartridge containing the cement powder. A feed plunger is arranged in the receptacle. A dispensing plunger is arranged between the monomer liquid container and the cement powder in the cartridge. The feed plunger can be punctured by a rod when motion of the feed plunger is blocked, whereby the dispensing plunger is propelled by propelling the rod further through the blocked and punctured feed plunger. Also provided are an extrusion device for propelling a feed plunger and a dispensing plunger of a device for mixing of a bone cement dough, and a method for the production of a bone cement dough.

A method for treating a spinal disorder includes the steps of: disposing an expandable spinal construct in a selected configuration; fixing the spinal construct in the selected configuration with a member; attaching a first end of the spinal construct with tissue; attaching a second end of the spinal construct with tissue; and disengaging the member from the spinal construct to release the spinal construct from the selected configuration. Implants, surgical instruments, systems and methods are disclosed.

A subperiosteal syringe assembly for storing, containing and delivering bone graft material to a location within the tissue of a jaw for use in a medical procedure. The syringe assembly has a lumen body that is maneuverable within the subperiosteal tissue to deposit bone graft material at the desired surgical site. Embodiments include a lumen body that has a flat shape, such as an elliptical shape. A plunger is provided to deliver the syringe contents. The syringe may be loaded with bone graft material, and some embodiments may be supplied pre-loaded with bone graft material. An end cap seals the open end of the lumen, and may function as a septum that may be punctured with a needle to introduce a liquid substance, such as a growth factor, into the lumen where the bone material is stored. The syringe may be designed to incorporate surgical navigation and laparoscopic systems.

Articulated instruments that include tools for disrupting and/or distracting tissue, and methods of using the same.

A bone cement applicator comprising a cartridge with an internal space. The cartridge has a head with a dispensing opening for expulsion of bone cement, a first thread, a dispensing plunger, a threaded tube having a counter thread engaging the first thread, a receptacle mobile in the threaded tube, and a mixing rod with a mixer fastened to it and arranged in the internal space of the cartridge. The mixing rod is detachably connected to the receptacle and is guided through a feedthrough in the dispensing plunger and is supported in the feedthrough so as to be axially mobile. When detached from the receptacle, the mixing rod can be pushed into the receptacle when the receptacle is propelled in the direction of the cartridge head. A method is also disclosed for production of a bone cement using the bone cement applicator.

A bone graft delivery system includes a rasp having an elongate body extending between a proximal end and a distal end, a lumen extending through the elongate body and configured to receive bone graft material, a rasping surface removably couplable to the distal end of the elongate body and configured to decorticate bone material of a patient, and one or more openings configured to deliver bone graft material from the lumen.
