• Stents are medical devices used to prop open coronary arteries following angioplasty, a procedure used to clear placque from arteries.
• This placque on the current Market Street Bridge ( Philadelphia ) illustrates the first bridge on Market Street ( Philadelphia ) over the Schuylkill River, and gives the history of subsequent bridges.
• In angioplasty, doctors snake a balloon-catheter into the blocked artery through a vein in the leg and inflate the balloon, cracking and pushing out the fatty-placque build-up.
