Drug dose and delivery facilitate early vessel recovery

  • ​Terumo's second-generation bioresorbable polymer coating (PDLLA /PCL) eliminates the long-term polymer exposure1
  •  Targeted abluminal drug delivery allows a reduced drug dose4
    • Half the amount required versus circumferential coating to deliver the same amount of drug to target tissue
    • Luminal side of the stent free from drug and polymer enhances endothelial coverage4

Gradient coating reduces risk of polymer cracking and delamination(3)

​​No drug polymer coating on parts of the stent that experience the most physical stress.5

Ultimaster provides the optimal balance between stent strut coverage, radial force, and visibility

  • ​Thick enough to:
    • Make the stent easy to see, for ease of deployment
    • Maintain radial force across the stent
  •  Thin enough to:
    • Maintain flexibility of the stent
    • Ensure stent coverage

The more complex the task, the more relevant the stent performance

  • Famous Terumo hydrophilic coating on delivery system, stent flexibility and smooth stent-balloon transition enable ultimate stent crossability
  • Low entry profile eliminates the gap between the tip and the guidewire for outstanding trackability

Designed towards facilitating the treatment of the most challenging bifurcations(6)

  • ​Open cell, 2-link design for easy side-branch access
  • Uniform architecture for optimal coverage of bifurcation anatomy
  • Gradient coating ensures polymer integrity reducing risk of delamination, even when overexpanded3

Side branch expansion

Test method: Expand a cell with a balloon at nominal pressure
Cell area: 14.5 mm²
