Endovascular Access

The Tycheseal^TM Thoracic Stent Graft System is designed to deliver reliable sealing, excellent conformability, and long-term clinical performance in the endovascular treatment of thoracic aortic pathologies. Its advanced stent architecture, combined with a low-profile delivery system, enables precise placement, controlled deployment, and adaptability to challenging anatomies.

Durable Sealing and Superior Conformability

• Dual short-strutted proximal stents (5 mm and 7.5 mm) provide secure sealing and excellent circumferential conformability.
• Nitinol alloy construction ensures an optimal balance between strong radial force and high flexibility.
• Multiple stent heights distributed along the graft enhance overall flexibility and anatomical adaptability.
• Increased distal stent height helps reduce mechanical stress while improving sealing performance and graft conformability.
• Designed to achieve low type I endoleak rates and durable long-term patency.

Smooth Delivery and Controlled Deployment

• Kink-resistant, low-profile delivery system (18Fr for stent grafts ≤28 mm) enables smooth and reliable navigation.
• Full hydrophilic coating facilitates easy advancement and controlled handling.

• Post-release deployment mechanism ensures precise and predictable stent graft release.
• Adjustable repositioning capability is maintained even after deployment of up to three stents.

Broad Anatomical Coverage and Versatility

• Specifically designed for the treatment of thoracic aortic aneurysms and dissections.
• Dual short-strut proximal stent design allows excellent conformability and supports a minimal proximal landing zone of 10 mm.
•  Suitable for a wide range of challenging anatomical conditions.
