International Classification:

A61B 17/56

US Classification:

606 86A, 606 99, 606 53, 81 5729

Abstract:

A vertebral implant assembly having a tubular body and a pair of endplate assemblies is installed between two vertebral endplates using an apparatus comprising an axle having a proximal end and a distal end, a set of gears connected to the proximal end of the axle, and an engager device connected to the set of gears and adapted to rotate the tubular body when the axle is rotated. As the tubular body is rotated, the vertebral implant assembly expands.

International Classification:

A61B 17/56

US Classification:

606 86A, 606 99, 606 53, 81 5759

Abstract:

An expansion assembly expands a vertebral implant. The vertebral implant has an inner cylindrical assembly adapted for insertion into an outer cylindrical assembly having an outer wall. The vertebral implant is expandable along an implant axis defined by the outer and inner cylindrical assemblies. The expansion assembly comprises an axle having proximal and distal end portions and an axle axis defined between the proximal and distal end portions. The expansion assembly further comprises a gear arranged about the axle axis at the proximal end portion of the axle and adapted to rotate about the axle axis to cause the inner cylindrical assembly to expand the vertebral implant. The engagement assembly also comprising a first engaging portion adapted to engage the inner cylindrical assembly and a second engaging portion adapted to engage the gear externally of the outer wall of the outer cylindrical assembly.

A61F 2/44

US Classification:

606 99, 606 86 A, 623 1711

Abstract:

Instruments for inserting an implant in a space between adjacent bony portions include upper and lower guide members separated by a spreader with the implant positioned forwardly of the spreader. The spreader is movable forwardly between the guide members with a drive member to position the implant in a space between the bony portions. The spreader contacts the adjacent bony portions to facilitate withdrawal of the inserter instrument when the implant is positioned in the space.

International Classification:

A61F 2/44

US Classification:

623 1715, 623 1711, 623 1716

Abstract:

An expandable spinal implant comprising a cage body including at least two movable branches having first end portions that are interconnected to one another and second end portions that are movable relative to one another. The movable branches include a first shell portion having a first pair of longitudinal edges and defining a first hollow region therebetween, and a second shell portion having a second pair of longitudinal edges and defining a second hollow region therebetween, with the first and second hollow regions cooperating to define at least a portion of a hollow interior of the cage body. An expansion member co-acts with the first and second shell portions to transition the cage body to an expanded configuration as the expansion member is axially displaced along said first and second pairs of longitudinal edges. In one embodiment, at least one of the shell portions defines a plurality of retention elements positioned at select axial locations along a corresponding one of the longitudinal edges, with the expansion member engaged with one or more of the retention elements to retain the expansion member at a select axial position to maintain the implant in the expanded configuration.
