Stent

In brief, a stent is a tiny tube that your doctor can insert into a blocked passageway to keep it open. The stent restores the flow of blood or other fluids, depending on where it's placed. Stents are made of either metal or plastic. Stent grafts are larger stents used for larger arteries. This was done for one of my undergraduate assignments. I this helps someone. I have added the parasolid file and STL file as requested.
