SELF-EXPANDING STENT
INDICATED FOR ATHEROSCLEROTIC DISEASE OF ILIAC ARTERIES

Astron is a stent designed for iliac artery lesions that are often calcified and occluded. Both stent and markers are completely coated with proBIO. Unique “S-articulations” allow stent conformability. Designed to account for vessel movement without compromising the necessary radial strength.


KEY FACTS
  • Pull-back delivery system for simple stent deployment
  • 5.2F proximal shaft for contrast injection with device in sheath
  • Segmented stent design and thick struts for sufficient chronic outward force
  • S-articulating connecting bars and peak-to-valley design for multi-directional flexibility

Product Details

Easy Release

  • Relieves friction of introducer valve on the retractable shaft during stent deployment for a smoother action.

Segmented Stent Design for Iliac Artery

  • Peak-to-valley design and S-articulating connecting bars provide multi-directional flexibility and avoid fish-scaling in tortuous arteries.
  • Segmented design and strut thickness designed to provide sufficient chronic outward force.

Enhanced Visibility

  • Four gold markers at each end of the stent enhance visibility.

Pull-Back Delivery System

  • Enables simple stent deployment.

Safety Tab

  • Avoids accidental stent deployment.

Improved Stent Surface Biocompatibility1

  • Excellent results with proBIO coated stents. Effective and reliable barrier to nickel and other metal ion diffusion.

6F Introducer Compatibility

  • 6F distal shaft with 5.2F proximal shaft for contrast injection with device positioned inside the introducer and across lesion.

BIOFLEX-I (US-IDE) Investigational Device Exemption Study to Determine the Safety and Efficacy of the Astron and Pulsar Stents

  • The objective of this study is to separately demonstrate the safety and efficacy of BIOTRONIK Astron and Pulsar stents. The Pulsar stent will be used for the treatment of femoro-popliteal lesions, located in the native superficial femoral artery (SFA) or proximal popliteal artery (PPA), while the Astron stent will be used for the treatment of the common or external iliac artery lesions. Estimated enrollment: 456

BIOFLEX-I EU: A Study to Determine the Performance of the Astron and Pulsar-18 Stents in Europe

  • BIOFLEX-I EU is the European arm of the BIOFLEX-I IDE study (NCT01319812). Data from BIOFLEX-I EU will be pooled with data in the IDE. The objective of this study is to separately demonstrate the clinical performance of BIOTRONIK's Astron and Pulsar-18 stents in the European arm of the BIOFLEX-I IDE (NCT01319812). The Pulsar-18 stent will be used for the treatment of femoro-popliteal lesions, located in the native superficial femoral artery (SFA) or proximal popliteal artery (PPA), while the Astron stent will be used for the treatment of the common or external iliac artery lesions. Estimated enrollment: 456

4-EVER: A Trial Investigating the Safety of 4 F Endovascular Treatment of Infra-Inguinal Arterial Stenotic Disease

  • The objective of this clinical investigation is to evaluate the puncture site complication rate as well as the short- and long-term (up to 24 months) treatment outcomes by means of Astron Pulsar/Astron Pulsar-18 stent implantation in symptomatic (Rutherford 2-4) femoro-popliteal arterial stenotic or occlusive lesions, using BIOTRONIK 4 F compatible devices and without the use of a closure device. The hypothesis is that the primary patency at 12 months is non-inferior to the primary patency obtained in the Durability study (72.2%). Enrollment: 120
