Indicated for femoral and proximal popliteal arteries. Being a relatively mobile artery, the Superficial Femoral Artery (SFA) requires a stent that conforms to the natural vessel movement and provides sufficient support in complex, long lesions that are often difficult to cross. Pulsar-35 is a stent designed for SFA with high multi-directional flexibility on a tri-axial delivery system.
- One-handed stent release for accurate stent deployment
- Tri-axial shaft for a stable delivery system during stent deployment
- S-articulating connecting bars and peak-to-valley design for multi-directional flexibility
- Segmented stent design with thin struts for lower restenosis rates
Isolates retractable shaft from friction caused by introducer valve, aimed at ensuring precision-like implantation accuracy.
Stent Designed for SFA
- Peak-to-valley design and S-articulating connecting bars provide multi-directional flexibility and avoid fish-scaling in mobile vessel architecture.
- A segmented design with thin struts provides low Chronic Outward Force (COF)1 sufficient to maintain vessel scaffolding even in calcified lesions (4EVER study)2. High COF has been shown to result in higher rates of neointimal hyperplasia.3
- Stent lengths up to 200 mm for covering long lesions with a single stent.
One-Handed Stent Release
Ergonomically designed for a comfortable and stable handling, enhancing ability to immobilize complete system during stent deployment.
- Safety tab: Avoids accidential stent deployment
- Trigger: For controlled stent delivery
Low Chronic Outward Force
Low Chronic Outward Force (COF)1 sufficient to maintain vessel scaffolding even in calcified lesions (4EVER study2). COF of Pulsar stents increases less than many competitor stents when oversized, thus potentially reducing inflammatory response and restenosis3.
