摘要：
A bioresorbable biopolymer stents can be deployed within a blood vessel and resorbed by the body over a predetermined time period after the blood vessel has been remodeled. A ratcheting biopolymer stent can include a ratcheting mechanism that allows the biopolymer stent to be deployed on a small diameter configuration and then expanded to a predefined larger diameter configuration wherein after expansion, the ratcheting mechanism locks the biopolymer stent in the expanded configuration. A folding biopolymer stent can be deployed in a folded, small diameter configuration and then expanded to an unfolded configuration having a larger diameter. The bioresorbable biopolymer can include silk fibroin and blend that include silk fibroin materials.
