Figure 1.

Abre venous stent design. The width and thickness of the struts on the Abre venous stent were altered for each stent diameter to achieve strength uniformity of all stent sizes, and the strut radii were opened selectively to achieve maximal fracture resistance. The stent has connection points that spiral down the stent (A, green circles). The stent cells are connected at 3 points around the circumference for maximum flexibility and kink resistance (A, blue squares). The Abre venous stent is easily seen under fluoroscopy (B, C) with 3 radiopaque markers on the cranial and caudal stent ends (see arrows on A, B, and C).
