November 11, 2013 — Biotronik announced that the PK Papyrus covered coronary stent system has received CE mark for the treatment of acute coronary artery perforation.
According to Biotronik, PK Papyrus boasts 58 percent greater flexibility than Abbott's Jostent Graftmaster due to its "electrospun" membrane. The enhanced electrospinning technology allows for a proprietary single-layer covered stent design rather than the traditional "sandwich technique" used on comparable stents on the market. The single-layer covered stent design, with its 90 ?m polyurethane membrane, further enables a 24 percent lower crossing profile in comparison to Abbott's Jostent Graftmaster, combining high flexibility and a low crossing profile for exceptional deliverability while sealing vessel defects in acute situations.
Many current covered stent designs require large French size guide catheters. Switching guide cathethers can cost the physician valuable time, delaying treatments. PK Papyrus is 5 and 6 French compatible, thereby eliminating the need to switch access catheters during these emergency situations.
"In acute situations when there is a vessel perforation, I need a stent that is highly effective and has optimum deliverability,” said Georg Nickenig, M.D., Ph.D., professor and chief, Department of Cardiology, University Hospital Bonn in Bonn, Germany. “With PK Papyrus, I am confident that, if such a situation arises, I have a stent that is straight-forward to introduce into the artery with a flexibility that means simplified placement."
While PK Papyrus is based on the same proven Orsiro/PRO-Kinetic Energy stent platform, the wide size range (diameter: 2.5-5 mm, length: 15-26 mm) enables a broad range of vessels to be treated confidently and efficiently.
