摘要： 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.

摘要： A resurfacing device for removing a thin layer of diseased tissue while minimizing damage to the underlying tissue layers may include an expandable scaffold attached to a catheter shaft, at least one electrode disposed on the expandable scaffold, and a plurality of debridement elements disposed on an outer surface of the expandable scaffold. The expandable scaffold is positioned in apposition to the target tissue, the scaffold is expanded and the electrodes are activated to ablate diseased tissue. The scaffold is rotated to remove the ablated tissue.

摘要： A medical device for treating a body lumen, such as a medical stent, includes an expandable scaffold configured to shift from a radially collapsed state to a radially expanded state. The stent includes a coating disposed along the outer surface of the expandable scaffold in which a portion of the coating includes a plurality of anti-migration members and one or more preferential separation regions. Each preferential separation region is configured to permit first and second regions of the coating to separate from one another along the preferential separation region therebetween as the expandable scaffold shifts from the radially collapsed state to the radially expanded state.
