Vascular Intervention // Coronary
Covered Coronary Stent System

PK Papyrus®

  Covered single stent design

  Low crossing profile

  Exceptional deliverability


PK Papyrus

Designed to save lives when seconds count.

Covered single stent design

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


Low crossing profile1




Innovative polyurethane membrane

Electrostatic forces spin polyurethane fibers onto the stent surface, creating a thin and highly elastic membrane.








Exceptional deliverability


58% greater flexibility2



Shorter median time to deliver

Single center, retrospective investigation of 61 patients treated with covered coronary stents.3,4

“In rare cases of a coronary perforation, time is the enemy.”

Dr. Dean Kereiakes, Interventional Cardiologist and Medical Director of The Christ Hospital and Vascular Center, Cincinnati, Ohio, USA.






5F Compatibility
