Exceptional deliverabilityᵇ¹⁻²

 Delivers like a conventional stent1

Covered single stent design

Enables a smaller crossing profile compared to the traditional sandwich design stent.b1

High bending flexibility¹

With its covered single stent design, PK Papyrus covered stent achieves greater bending flexibility and a smaller crossing profile compared to the traditional sandwich design stentb, allowing you to seal perforations with confidence.1 

Innovative polyurethane membrane

Unique manufacturing method allows for an ultrathin membrane capable of sealing vessel perforations. Electrostatic forces spin polyurethane fibers onto the stent surface, creating a thin and highly elastic membrane.

Low crossing profile¹

23% reduction in crossing profile compared to the traditional sandwich design stent.b1

5F Compatibility for main sizes

The low crossing profile also means there is no need for a guide catheter upgrade on main sizes (Ø 2.5 – 4.0 mm). 

Exceptional deliverabilityᵇ¹⁻²

Expect a high performing platform with an ultra thin membrane to deliver like a conventional stent.1

81% greater flexibility

PK Papyrus covered stent achieves 81% greater flexibility compared to the traditional sandwich design stent.b1

Shorter median time to deliver

Single center, retrospective investigation of 61 patients treated with covered coronary stents, show that PK Papyrus covered stent uses up to 47% less time to deliver compared to Jostent Graftmaster coronary stent graft system (PTFE-CS).c2
