Ultimaster™

Sirolimus Eluting Coronary Stent System

Description

Understanding complexity, for optimal vessel recovery

Pushing the boundaries of science and medical engineering for the improvement of health: Ultimaster combines an optimal balance between stent design for ultimate conformability with simultaneous polymer resorption and drug release, to match the procedure-triggered biological response in the vessel.1 This results in optimal vessel recovery and potentially shortened DAPT time.2

Mastering rapid and healthy coronary vascular repair.

Characteristics

  • 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 delamination3

    ​​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 bifurcations6

    • ​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
