Endovascular Access

The Tycheseal^TM Abdominal Aortic Stent Graft System is designed to deliver a durable seal with active fixation and excellent graft conformability for the endovascular treatment of abdominal aortic aneurysms. Its innovative stent and graft design enables smooth delivery, precise positioning, and well-controlled deployment, while supporting long-term clinical performance and reliable patency across a broad range of anatomies.

Durable Sealing and Superior Graft Conformability

• Provides a durable seal with active fixation, low type I endoleak rates, extremely low type II endoleak incidence, and excellent long-term patency.
• Optimized M-shaped proximal stents ensure a durable seal and superior circumferential conformability.
• Single-suturing design enhances graft flexibility.
• Nitinol alloy construction achieves an optimal balance between strong radial force and excellent conformability.
• Anchoring pins on the suprarenal stent provide active fixation, minimizing the risk of device migration.

Smooth Delivery and Controlled Deployment

• Kink-resistant, low-profile delivery system (16Fr for stent grafts ≤22 mm), combined with a hydrophilic coating, enables smooth and reliable delivery.
• Equal-sign-shaped markers support precise positioning and accurate placement.
• Post-release deployment mechanism ensures controlled and predictable stent graft deployment.
• Adjustable repositioning capability is maintained even after deployment of up to three stents.

Broad Anatomical Coverage and Versatility

• Three-piece design allows flexible and adjustable overlap options.
• Optimized M-shaped proximal stents and single-suturing design provide excellent flexibility and conformability.
• Supports challenging anatomies, including a minimal proximal landing zone of 10 mm and infrarenal angulation of up to 75°.
• Designed to accommodate a wide range of clinical indications in endovascular AAA repair.
