Publication number: 20110153021Abstract: A nucleus pulposus replacement device comprises a body of an elastomeric material which is able to be introduced and positioned within an annulus of an intervertebral disc of a patient. The material is of a form which undergoes a change from a first state, in which the body of material is able to conform substantially to a shape of a nuclear cavity of the intervertebral disc, to a second state, in which the body of material mimics bio-mechanical properties of a natural, healthy nucleus pulposus of an intervertebral disc. The material is of a consistency which inhibits leakage from an annulus fibrosis of the intervertebral disc.Type: ApplicationFiled: August 20, 2010Publication date: June 23, 2011Applicant: SPINECELL PTY LTD.
