Abstract
The invention provides a compliant stent graft for deployment in the descending aorta to reduce the clinical impact of a stiffened aorta. The compliant stent graft includes a tubular body which extends between a proximal end and a distal end and comprises a proximal anchor section ending at the proximal end and a distal anchor section ending at the distal end. Each section is adapted to move from a constricted state to a dilated state. A treatment section is interposed between the proximal and the distal anchor sections, which is adapted to move from an unexpanded state, having a first volume to an expanded state, having a second volume, wherein, in the unexpanded state, the treatment section has an unexpanded diameter which is less than a constricted diameter of the distal and proximal anchor sections in the constricted state and wherein the difference between the first volume and the second volume is sufficient to retain between 20% and 70 % of the volume of blood ejected during systole.
