New dissolving stent could save legs from amputation

This early study tests a special scaffold that dissolves over time in 10 people with severe leg artery disease (critical limb-threatening ischemia). The scaffold is placed in arteries below the knee to help keep them open after balloon treatment. Researchers check safety and how well the scaffold works at 30 days, 6 months, and 12 months using ultrasound. The goal is to restore blood flow and avoid amputation.
