BERN Registry

Evaluate long segment (> 120 mm) complex femoro-popliteal disease with Pulsar stent stratified for Critical Limb Ischaemia vs. Intermittent Claudication1


  • Endovascular stenting of long femoro-popliteal lesions using the Pulsar-18 stent provides acceptable results, with patency and restenosis rates comparable to data from the literature for stenting of long femoro-popliteal obstructions.
