Abstract
Methods and apparatuses of atraumatic stents with likely reduced rates of tissue perforation are provided. The stents of the invention have crowns with crown tips having apexes made of a radial force reducing material. The apexes are soft and flexible and reduce the radial force at the crown relative to the stent body allowing the crowns to collapse with greater ease compared to the central portion of the stent.
