Medical device maker Boston Scientific Corp. said Monday the Food and Drug Administration approved its new stent system aimed at propping open arteries that supply blood to the kidneys.
The Express SD Renal Monorail Premounted Stent System is approved for use in addition to renal angioplasty, which also refers to the kidneys.
Renal artery disease occurs when the main blood supply to the kidneys narrows because of plaque or atherosclerosis. Stents are tiny mesh tubes intended to help hold arteries open.
Shares of Boston Scientific rose 18 cents, or 2.5 percent, to $7.35 in afternoon trading. The stock has traded between $5.41 and $14.22 over the past 52 weeks.
