Inward spiral design of Nautilus Coil minimizes tissue contact for enhanced comfort. Dual variable length coil geometry permits balanced stent positioning to minimize the risk of migration. HydroPlus Coating provides unequalled surface lubricity which reduces friction to minimize risk of buckling during introduction and placement and to reduce risk of trauma and encrustation.
