LINC 2019: BIOTRONIK Introduces the First Tri-axial 4-French Low-Profile Stent System

Pulsar-18 T3 Self-Expanding Stent Designed for More Effective Lesion Treatment in the Superficial Femoral, Proximal Popliteal and Infrapopliteal Arteries up to 200 mm

BIOTRONIK presented the innovative Pulsar-18 T3 stent system for the first time during LINC 2019 in Leipzig this week.

The Pulsar-18 T3 system is a unique combination of three technologies for an improved implantation procedure. The 4-French low profile decreases the risk of access site complications1 and reduces the need for closure devices compared to 6-French, while the tri-axial shaft design facilitates stable and accurate implantation of the clinically proven Pulsar stent. The intuitive and ergonomic wheel-operated handle simplifies handling during the procedure for physicians.

The superficial femoral artery (SFA) requires a stent that conforms to the natural vessel movement and provides sufficient support in complex and long lesions. The new device unifies proven technologies for efficient delivery of stents up to 200 mm to the challenging SFA. The thin struts, low chronic outward force (COF) and high multidirectional flexibility of the Pulsar stent ensure conformability and support to the vessel in all natural vessel movements.

“Pulsar-18 T3 is a unique innovation; this is the first time physicians have access to a self-expanding stent system that combines the benefits of 4-French with the accurate deployment of a tri-axial system,” stated Dr. Alexander Uhl, Senior Vice President Corporate Marketing at BIOTRONIK. “Pulsar-18 T3 represents BIOTRONIK’s dedication to providing effective therapies which minimize burden and reduce risks to patients.”
