Endovascular Access

The Tycheseal Abdominal Aortic Stent Graft System delivers a reliable and durable seal through active fixation and excellent graft conformability. It demonstrates low rates of type I and type II endoleaks, along with outstanding long-term patency. Its innovative design enables smooth delivery, accurate positioning, and controlled deployment. In addition, the system effectively addresses challenging anatomies and supports a broad range of clinical indications.

Durable sealing and superior graft conformability
Provides active fixation with 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.
The single-suture design enhances graft flexibility.
The nitinol alloy 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 precise deployment
A kink-resistant, low-profile delivery system (16Fr for stent grafts ≤22 mm), combined with a hydrophilic coating, enables smooth advancement.
Equal-sign–shaped markers allow accurate positioning.
The post-release mechanism ensures controlled and predictable deployment.
Repositioning capability is available even after deployment of up to three stents.

Broad anatomical coverage and wide indications
The three-piece configuration allows flexible and adjustable overlap options.
Optimized M-shaped proximal stents and the single-suture design provide excellent flexibility and conformability, accommodating a minimal proximal landing zone of 10 mm and infrarenal angulation of up to 75°.
