| 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 |
| 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 |
