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

LEIPZIG, Germany and BUELACH, Switzerland, January 22, 2019 – 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.”

A New Delivery System for Clinically Proven Technology

While introducing the new features to enhance deployment, the new stent system builds on the established Pulsar-18 stent. Recent data highlighted the long term safety and efficiency of Pulsar-18 by showing a freedom from target lesion revascularization rate of 92.4% at 24 months.2

The 4-French delivery system offers a number of benefits, including clinically proven lower access site complication rates and a reduced need for closure devices compared to 6-French stents.3 With its low COF4 and thin struts of 140 µm, Pulsar-18 is proven to cause less vessel injury and inflammation5, provide faster endothelialization6 and lower the risk of restenosis.7

Pulsar-18 T3 is indicated for use in patients with atherosclerotic disease of the superficial femoral, proximal popliteal and infrapopliteal arteries and for the treatment of insufficient results after percutaneous transluminal angioplasty (PTA), e.g. residual stenosis and dissection.
