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.

Abstract: An example medical stent for treating a body lumen is disclosed. The example stent includes an expandable scaffold having a first end region, a second end region and an outer surface. The stent further includes a first fixation member coupled to the expandable scaffold and a biodegradable material disposed along the first fixation member at a first tissue engagement region. Further, the biodegradable material is designed to degrade from a first configuration in which the biodegradable material shields the first fixation member from a target tissue site to a second configuration in which the first fixation member is engaged with the target tissue site.
