Abstract
Embodiments of the invention provide compositions include bio degradable polymers, medical implants fabricated from these compositions and methods of using such implants. Many embodiments provide medical implants including a first polymer backbone having a first rate of biodegradation and a second polymer backbone having a second rate of biodegradation faster than the first rate. In some embodiments, the second backbone is configured to be replaced by a natural tissue layer. The first backbone provides a scaffold for the implant while the second backbone degrades. This scaffold can enhance mechanical properties of the implant including various aspects of mechanical strength such as tensile, bending, hoop and yield strength; and elasticity. The scaffold also serves to maintain a minimum level of structural support of the implant during the period of degradation of the second backbone or for the entire life of the implant so that the implant does not mechanically fail.
