Biodegradable polymers are currently limited in their application in engineering of soft tissues because they are too stiff and incompliant. Biodegradable elastomers overcome these limitations; they have ability to recover from multiple deformations. Citric Acid based Biodegradable Polymers (CABEs) are a family of elastomers that have been recently developed. Further developments in this area are still needed but they provide a promising new material that can be used for drug delivery systems.
