SMart 360° Pistons


SMart 360° Pistons

The SMart 360° Piston is a completely encircling piston loop containing heat-activated nitinol (nickel-titanium alloy). Nitinol exhibits shape memory, returning to its original shape when heated, which dramatically simplifies the crimping maneuver. SMart 360° Pistons are available in a broad array of diameters and functional lengths.

Key Benefits

SMart® Piston Technology
Olympus offers Nitinol, a shape-memory alloy, for middle-ear implants.

The reason Stapes surgery is challenging is that there is little tolerance for
error. SMart Piston technology incorporates our patented “self-crimping” Nitinol
alloy which simplifies Stapes surgery by taking the worry out of crimping.

  • Nitinol (nickel-titanium alloy) is a shape-memory metal alloy that has been used in medical applications for years. Since Nitinol “self-fashions” with heat, the crimping maneuver is dramatically simplified.
  • The SMart 360º Piston is a completely encircling piston containing heat-activated Nitinol.
  • The SMart 360º Piston has a shape memory property that allows the piston loop to hug the incus circumferentially.
  • The SMart De La Cruz Piston simplifies stapes surgery with its self-measuring body. This self-measuring feature improves a surgeon’s ability to measure implant length accurately.
  • MRI-compatible up to 3 Tesla.*
