Abstract
A method of protecting a spinal area of a patient includes the step of positioning a sheet of collagen membrane material so as to surround at least a portion of a patient's spinal chord. The sheet of collagen membrane preferably includes at least one barrier layer with a smooth face to inhibit cell adhesion and act as a barrier to prevent passage of cells therethrough. When surgery involves placement of s vertebrae replacement material between vertebrae, the collagen membrane material can be positioned so as to surround at least a portion of the vertebrae replacement material.
Claims16
A method of protecting a spinal area of a patient comprising positioning a sheet of resorbable collagen membrane material so as to substantially wrap the collagen membrane material around a patient's spinal chord wherein said collagen membrane material is comprised of at least one barrier layer having at least one smooth face so as to inhibit cell adhesion thereon and act as a barrier to prevent passage of cells therethrough.
A method of protecting a spinal area of a patient comprising positioning a sheet of resorbable collagen membrane material so as to substantially wrap the collagen membrane material around a patient's spinal chord, wherein said sheet is positioned adjacent a dura sheath of said spinal chord, so as to protect said dura sheath, further comprising the step of inserting a vertebrae implant material outside said sheet adjacent said dura sheath, and further positioning a second sheet of collagen membrane material around at least a portion of said vertebrae implant material.
A method of protecting a spinal area of a patient in which a vertebrae implant material has been positioned adjacent to the patient's spinal chord in an intervertebral space between two vertebrae, comprising positioning a sheet of resorbable collagen material adjacent the intervertebral space so as to substantially wrap the collagen membrane material around the vertebrae implant material.
