Abstract: Medical stent designs are disclosed. An example stent includes a tubular scaffold having a proximal end and a distal end. The tubular scaffold includes a first filament extending between the proximal end and the distal end, the first filament including a first biodegradable region positioned adjacent to a second biodegradable region. Further, the first biodegradable region includes a first biodegradable material, the first biodegradable material having a first rate of degradation. The second biodegradable region includes a second biodegradable material, the second biodegradable material having a second rate of degradation, wherein the first rate of degradation is different from the second rate of degradation.
