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 |
20120290097 | EXPANDABLE INTERVERTEBRAL IMPLANT - A method of inserting an expandable intervertebral implant is disclosed. The implant preferably includes first and second members capable of being expanded upon movement of first and second wedges. The first and second wedges, while being capable of moving with respect to each other and the first and second members are also preferably attached to the first and second members. In addition, the first and second wedges are preferably capable of moving only in a first direction, while movement in a second direction is inhibited. The first and second wedges are also preferably prevented from torsionally moving with respect to the first and second members. | 11-15-2012 |
20140039629 | EXPANDABLE INTERVERTEBRAL IMPLANT - A method of inserting an expandable intervertebral implant is disclosed. The implant preferably includes first and second members capable of being expanded upon movement of first and second wedges. The first and second wedges, while being capable of moving with respect to each other and the first and second members are also preferably attached to the first and second members. In addition, the first and second wedges are preferably capable of moving only in a first direction, while movement in a second direction is inhibited. The first and second wedges are also preferably prevented from torsionally moving with respect to the first and second members. | 02-06-2014 |
