摘要：
The present application is directed to devices and methods for spacing apart spinous processes. In one embodiment, the device includes a body having a central portion that separates first and second sections. The body is constructed of a combination of an elastic material and a bio-absorbable material. When initially implanted within a patient, the bio-absorbable material affects the stiffness of the device. The device stiffness changes to that of the elastic material as the bio-absorbable material is absorbed by the body.
