Self locking fixable intervertebral implant
First Claim
1. An intervertebral implant to be placed between spinous processes of two vertebrae comprising:
- a block having two opposite sides in the direction of a longitudinal axis, each side being provided with a groove adapted to receive said spinous processes, said block further having two lateral walls;
a fixing tie for retaining said spinous processes in said grooves, said fixing tie having a first end adapted to be connected to said block and a second free end, said fixing tie being adapted to surround at least one spinous process;
a removable self-locking fixing member having first connecting means and through which said fixing tie can slide when it moves in translation in a first direction, said self-locking fixing member being adapted to immobilize said fixing tie against movement in translation in a second direction opposite said first direction; and
at least one of said lateral walls of said block including second connecting means to cooperate with said first connecting means to connect said removable self-locking fixing member to said at least one of said lateral walls, a movement of said free end of said fixing tie to move said fixing tie in translation in said first direction causing said spinous process to be clamped in said groove and said fixing tie to be immobilized against movement in translation relative to said block in said second direction.

Abstract
An intervertebral implant which includes a block (10) with two grooves (12, 14) on opposite sides and on the longitudinal axis (A) of the block (10). The block (10) has two lateral walls and a fixing tie (16), where a first end (20) of the fixing tie (16) is adapted to be connected to the block (10) and a second end (28) of the fixing tie is a free end. The intervertebral implant includes a removable self-locking fixing member (30, 32) which is connectable with studs (34) and through which the fixing tie (16) can slide. A lateral wall (36) of the block (10) includes housings (38) adapted to cooperate with the (34) to connect the removable self-locking fixing member (30, 32) to the lateral wall (36) of the the block (10).
