Venous Stent Graft

It is indicated for the treatment of upper extremity venous outflow stenosis of patients dialyzed with an arteriovenous (AV) access graft or fistula.

The stent is delivered placed between the inner catheter and the outer sheath, located in the distal portion of the graft delivery system. In such a compressed arrangement, the supports of the nitinol stent are positioned close to each other.

The flexible release system is a coaxial catheter system consisting of an internal catheter integrated into the system via a metal tubing shaft and a coaxial outer sheath connected to the Y-injection adapter via the Tuohy-Borst valve.

Superior Performance with Innovative Design.

Helical Design for Radial Strength and Flexibility.

- Atraumatic tip designed to facilitate smooth entry and exit at the access point

- Straight and flared configurations to optimize hemodynamic flow in the venous anastomosis

- Full encapsulation between two ePTFEs designed to resist neointimal hyperplasia at the treatment site

- Designed to withstand bending, compression and stretching in combination with spiral posts and angled bridges

- Tantalum markers to increase visibility under fluoroscopy.

Proven to have effective propulsion, tracking and visibility under fluoroscopy on a low profile delivery system in a preclinical model.
