Intervertebral implant with elastically deformable wedge
First Claim
1. An intervertebral implant comprising a spacer for placing between two spinous processes of two vertebrae of the spine, said spacer comprising:
- two elements each presenting a first part provided with a groove configured to receive a spinous process and a bearing second part opposite from said first part, said bearing second parts of said two elements being situated facing each other;
elastically-compressible means disposed between said bearing second parts, said elastically-compressible means being compressed by said bearing second parts when said two elements are driven towards each other;
link means distinct from said elastically-compressible means for linking together said two elements, said link means blocking translation movement of said two elements relative to each other when said two elements are driven apart from each other; and
connection means for connecting the first part of one of said two elements to the spinous process disposed within said groove.

Abstract
An intervertebral implant comprising a spacer for engaging between two spinous processes of two vertebrae of the spine. The spacer has two elements each presenting a first part suitable for being connected to a spinous process and bearing second parts opposite from the first part, the bearing second parts being situated facing each other. An elastically-compressible member is disposed between the bearing second parts. Links are provided which are distinct from the elastically-compressible member for linking together the two elements, the link member being suitable for blocking translation movement of the two elements relative to each other when the two elements are driven apart from each other.

13. An intervertebral implant comprising a spacer for placing between two spinous processes of two vertebrae of the spine, said spacer comprising:
-
two elements each presenting a first part provided with a groove configured to receive a spinous process and a bearing second part opposite from said first part, said bearing second parts of said two elements being situated facing each other; elastically-compressible means formed as a single piece of elastomer disposed between said bearing second parts, said elastically-compressible means being compressed by said bearing second parts when said two elements are driven towards each other; link means distinct from said elastically-compressible means for linking together said two elements, said link means blocking translation movement of said two elements relative to each other when said two elements are driven apart from each other; and connection means for connecting the first part of one of said two elements to the spinous process disposed within said groove. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
