Title:
PROSTHETIC NUCLEUS APPARATUS AND METHODS
Document Type and Number:
WIPO Patent Application WO2006020531
Kind Code:
A3
Abstract:
Prosthetic nucleus apparatus (10) and methods for treating an intervertebral disc are disclosed. Prosthetic nucleus apparatus (10) may include a barrier sealant membrane (12) and a prosthetic nucleus material (14). The barrier sealant membrane (12) forms a chamber (24) which can receive the prosthetic nucleus material (14). The barrier sealant membrane (12) can be formed by depositing a layer of material on a tissue surface (102) within a de-nucleated space (104) within an intervertebral disc (100). The prosthetic nucleus material (14) may be positioned within the chamber (24) of the barrier sealant membrane (12) after the barrier sealant membrane (12) is deposited within the de-nucleated space (104). The barrier sealant membrane (12) and the prosthetic nucleus material may be positioned within a patient through an axial trans-sacral bore (410). A plug 16 may also be included to prevent expulsion of the barrier sealant membrane (12) and prosthetic nucleus material (14).
