Abstract:
A stent assembly (10) includes a branch portion (25) and a main body (12) with a proximal (15) main body, a contralateral main body (20), and a distal main body (30). The branch portion is in fluid communication with the main body. In the expanded state the branch portion extends at an oblique angle in relation to the longitudinal axis. The main body and the branch portion are at least partially constructed of interconnected struts. A plurality of the struts are connected one to another by a peak. The distal main body has a greater peak width to strut width ratio than does the proximal main body and contralateral main body.
