| 20080247262 | BONE CEMENT CARTRIDGE WITH A RELEASABLY LOCKED DRIVE PISTON, THE PISTON CONFIGURED TO BE UNLOCKED BY A DELIVERY DEVICE - A bone cement mixing and delivery system is provided. The system includes a mixing cartridge for receiving liquid and powder components of bone cement, a mixing blade for mixing the components, and a delivery gun for discharging the bone cement from the mixing cartridge. The mixing cartridge comprises a cylinder having proximal and distal ends with a cylinder wall extending between the ends. A piston is locked at the distal end by a locking member that includes a pair of locking tabs protruding into slots in the cylinder wall. With the piston in the locked position, the mixing blade mixes the components. After mixing, the cartridge is placed in the delivery gun and release buttons on the locking member are engaged by a release mechanism on the delivery gun to release the piston from the locked position. | 10-09-2008 |
| 20090257306 | BONE CEMENT MIXING AND DELIVERY SYSTEM WITH AUTOMATED BONE CEMENT TRANSFER BETWEEN MIXER AND DELIVERY DEVICE AND METHOD OF MIXING AND AUTOMATED TRANSFER OF BONE CEMENT BETWEEN MIXER AND DELIVERY DEVICE AND METHOD OF MIXING AND AUTOMATED TRANSFER OF BONE CEMENT BETWEEN MIXER AND DELIVERY DEVICE - A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a mixing paddle and a mixing shaft connected to the mixing paddle. A motor operatively engages the mixing shaft to rotate the mixing shaft and the mixing paddle to mix the components in a mixing chamber. The motor also operatively engages a transfer mechanism. After a predetermined mixing period has elapsed, the motor automatically actuates the transfer mechanism to transfer the mixture to a delivery device. The mixture is then delivered to a target site, such as a vertebral body of a patient or other anatomical site. | 10-15-2009 |
| 20100036381 | CAVITY CREATOR WITH INTEGRAL CEMENT DELIVERY LUMEN - A cavity creator including a tube with a lumen. A tip able to penetrate bone extends forward from the distal end of the tube. A blade is moveably attached to the outer tube proximal to the tip so as to move between retracted and extended states. The tube has a discharge port adjacent the blade. The tip is used to position the upper tube in bone. The blade is extended to form a cavity in the bone. Once the cavity is created filler material can be introduced into the cavity by flowing the material through the tube lumen. | 02-11-2010 |
| 20100110820 | MOTORIZED BONE CEMENT MIXING AND DELIVERY SYSTEM THAT AUTOMATICALLY TRANSFERS BONE CEMENT BETWEEN THE MIXER AND THE DELIVERY DEVICE AND THAT AUTOMATICALLY TERMINATES THE MIXING AND DELIVERY PROCESSES - A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a paddle for mixing the components in a mixing chamber and a piston that pushes the mixing cement into an attached delivery device. The system further includes a switch that disconnects the drive assembly that actuates the paddle and piston from its power source. The switch is automatically tripped by a follower that moves upon actuation of the drive assembly. Once the cement is mixed and transferred to the delivery device, the follower trips the switch to automatically deactivate the drive assembly. | 05-06-2010 |
| 20110085411 | CARTRIDGE IN WHICH BONE CEMENT IS MIXED AND FROM WHICH BONE CEMENT IS DELIVERED, THE CARTRIDGE HAVING A COMPRESSIBLE BLADE WITH PLURAL VANES - A cartridge in which bone cement is mixed and from which the cement is discharged. A blade with plural vanes is disposed in the cartridge for mixing the cement. A piston located in one end of the cartridge is actuated to push the mixed cement out of the cartridge. The blade has plural vanes, one for scraping cement off the side of the cartridge, one for scraping cement off the piston and one for scraping cement off the end of the cartridge opposite the end in which the piston is normally located. The blade is collapsible so that when the piston is actuated the blade compresses to allow the cement in the cartridge to be pushed out. | 04-14-2011 |
| 20110194371 | MOTORIZED BONE CEMENT MIXING AND DELIVERY SYSTEM THAT ALLOWS A USER TO DETACH THE DELIVERY DEVICE FROM THE MIXER FOR DELIVERY - A bone cement mixing and delivery system including a mixer and a delivery device. The mixer includes a paddle for mixing the components and a piston that pushes the mixed cement into the attached delivery device. The delivery device includes a tube into which the bone cement is forced from the mixer, and a plunger that forces the cement out of the tube during the medical procedure. The tube includes an entry port through which cement is introduced into the tube from the mixer. A one-way valve attached to the tube allows the cement to flow from the mixer through the entry port. After the cement is loaded in the tube, the delivery device is removed from the mixer. The valve blocks flow out of the entry port when the plunger is depressed. | 08-11-2011 |
| 20120057425 | CARTRIDGE FROM WHICH BONE CEMENT IS DISCHARGED, THE CARTRIDGE HAVING A REMOVABLE COUPLE NOZZLE - A cartridge in which bone cement is mixed and from which the cement is discharged. A blade with plural vanes is disposed in the cartridge for mixing the cement. A piston located in one end of the cartridge is actuated to push the mixed cement out of the cartridge. The blade has plural vanes, one for scraping cement off the side of the cartridge, one for scraping cement off the piston and one for scraping cement off the end of the cartridge opposite the end in which the piston is normally located. The blade is collapsible so that when the piston is actuated the blade compresses to allow the cement in the cartridge to be pushed out. | 03-08-2012 |
| 20120218851 | MOTORIZED BONE CEMENT MIXING AND DELIVERY SYSTEM WITH A FLEXIBLE DELIVERY EXTENSION TUBE AND ENLARGED CONNECTOR FOR DELIVERING CEMENT INTO LIVING TISSUE - A bone cement mixing and delivery system including a mixer, a delivery device, and a flexible extension tube. A connector is attached to a distal end of the flexible tube. The connector includes a housing, a spindle configured with a fitting, and an enlarged knob. The spindle is seated within the housing and is configured to rotate between a closed and open position. In the open position, the spindle allows flow from the delivery device flexible extension tube into a bore of the spindle and into the spindle fitting. A delivery cement cannula is attached to the spindle fitting for allowing cement to travel from the delivery tube into living tissue. The enlarged knob is used to rotate the spindle from an open to a closed state and vice versa. | 08-30-2012 |
| 20130090661 | DELIVERY GUN FOR DISPENSING BONE BEMENT FROM A CARTRIDGE, THE GUN HAVING A MULTI-LINK LINKAGE AND CAPABLE OF DISPENSING THE CEMENT AT DIFFERENT FLOW RATES - A delivery gun for discharging bone cement from a cartridge that includes a piston. The gun has a casing from which a drive rod and a disk extend. A drive assembly advances the drive rod and disk so that disk displaces the piston causing the discharge of cement. The drive assembly includes plural links that are pivotally connected to a trigger. The links are displaced in response to the manual displacement of a trigger. One of the links is configured to selectively engage the drive rod. When this particular link is engaged with the drive rod and displaced, the drive rod the drive rod is advanced at a first speed. When this link does not is not engaged with the drive rod, the drive rod is advanced by another link at a second speed. | 04-11-2013 |
