Abstract
In accordance with one or more implementations of the present invention, a flexible mesh bag including a catenoidal central portion (106) and two bulbous end portions (104, 108) may be employed as a spinal spacer. The mesh may be percutaneously implanted between adjacent spinous processes (202, 204) to correct the position and orientation of a spine and thereby relieve any discomfort associated with spinal stenosis. Additionally, the mesh may be filled with a bone graft material to permit bone fusion for long-term stability.
Claims8
A spinal implant for use in adjusting the position and orientation of adjacent spinous processes comprising:
- a bone graft material;
- and
- a flexible and expandable biocompatible mesh bag containing bone graft material including
- two bulbous end portions of spherical shape configured to secure the implant in a position;
- and
- a central portion having a catenoidal shape and joining said end portions together having a width that is less than the widths of the at least two end portions that is configured to adjust the position and orientation of adjacent spinous processes by applying expansive pressure on the spinous processes when the catenoidal shaped portion of the biocompatible mesh bag is filled with the bone graft material.
