Abstract:
1. An interspinous implant for implantation between two adjacent spinous processes, comprising: first and second arms forming a concave recess configured to receive one of the adjacent spinous processes; an inner central portion made from a first elastically deformable material, the inner central portion having: first and second outer lateral portions made from a second elastically deformable material more rigid than said first elastically deformable material, said first and second lateral portions being situated on opposite lateral sides of the first and second outboard surfaces of the inner central portion and adapted to be located along each side of the spinous processes after implantation, wherein the first and second outer lateral portions form at least part of the first and second arms respectively; wherein the first and second arms each have respective heights, and wherein said second elastically deformable material of the first and second outer lateral portions extends over a portion of the height of at least one of the first and second arms; wherein the concave recess is a first concave recess and the inner central portion is a first inner central portion and wherein the implant further comprises: third and fourth arms forming a second concave recess configured to receive the other of the adjacent spinous processes; a second inner central portion made from the first elastically deformable material; the second central portion having: third and fourth outer lateral portions made from the second elastically deformable material, the third and fourth lateral portions being situated on opposing lateral sides of the first and second outboard surfaces of the second inner central portion, wherein the third and fourth lateral portions form at least part of the third and fourth arms respectively; wherein at least one of the first and second lateral portions and at least one of the third and fourth lateral portions has a reduced thickness portion so as to allow bending of the corresponding arms on the same side of the implant towards each other.
