Vascular Intervention // Coronary
Covered Coronary Stent System
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.
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.
