| 20090048604 | Insertion instrument for intervertebral implants - An insertion tool for positioning intervertebral spacers into disc spaces. The insertion tool has a proximal end and a distal end, a T-handle secured to the proximal end and a pair of alignment rails extending to the distal end. The insertion tool includes a handle secured to the proximal end of the guide rails, and a shaft that extends through the handle, whereby the shaft has a threaded portion that extends to the T-handle. The insertion tool also includes a blocker that is secured to the distal end of the shaft. The blocker includes stop arms that guide the blocker through the guide rails and toward the distal end of the shaft. The blocker may be provided in a plurality of different sizes corresponding to the sizes of the implants to be inserted into a disc space. A lock is provided for locking the implant to the shaft. | 02-19-2009 |
| 20090222100 | Tool for implanting expandable intervertebral implant - An expandable intervertebral implant and tool for use in implanting same are disclosed. The tool is useful in retaining the implant in a non-expanded state throughout insert of the implant between adjacent vertebral bodies. Among other elements, the tool includes a rod, a sleeve placed over the rod, and a locking knob attached to the rod and the sleeve to fix them with respect to each other. This construct preferably aids in preventing movement of the various components of the implant, including first and second members and first and second wedges. A method of attaching inserting the implant through the use of the tool and attaching the tool to the implant are also disclosed. | 09-03-2009 |

| 20080221531 | FLUSH SYRINGE HAVING COMPRESSIBLE PLUNGER - An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end with a passageway therethrough in fluid communication with the chamber. An elongate plunger having a proximal end, a distal end and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel for drawing fluid into and out of the chamber by movement of the stopper relative to the barrel. The plunger includes anti-reflux structure for minimizing stopper deflection when fluid has been delivered from the chamber and the stopper is being forced against the distal end of the chamber. | 09-11-2008 |

| 20080262439 | Positive Displacement Flush Syringe - A positive displacement flush syringe includes a barrel having a chamber for retaining fluid and an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with the chamber. A plunger having a stopper which is slidably positioned in said chamber for driving fluid out of the chamber by movement of the stopper relative to the barrel is provided. Further, structure is provided to move fluid distally in the passageway after fluid has been delivered from the chamber and the stopper is in contact with the distal wall of the chamber. | 10-23-2008 |
