Patent ID: 8747453

Claim:
A stent/stent graft for treating a vascular abnormality in a lumen, the stent/stent graft comprising: a flexible tubular structure comprising a proximal end and a distal end, the flexible tubular structure having a heat set configuration and an expanded configuration, the heat set configuration having a heat set diameter and the expanded configuration having a maximum expandable diameter of the flexible tubular structure, wherein the flexible tubular structure is heat set in the heat set configuration such that the heat set diameter between the proximal and distal ends of the flexible tubular structure is larger than a diameter of at least one of the proximal or distal ends of the flexible tubular structure and is smaller than a maximum diameter of the vascular abnormality, and wherein the flexible tubular structure is configured to expand from the heat set diameter to the maximum expandable diameter in response to a distally directed axial compressive force such that the flexible tubular structure is configured to conform to the maximum diameter of the vascular abnormality.
