Tube-like stent to replace the aorta ascendens

摘要

The prosthesis (1) has a wall section (2) running linearly in aortal sinus area, where the wall section includes three circumferential sections (5), and reinforcements (7) formed between the circumferential sections and run longitudinally. The circumferential sections are expandable in a transverse direction of the prosthesis, where the circumferential sections possess increased expansibility with respect to the prosthesis.
