A perfusion device for repair of a damaged portion of a body vessel, comprising: a tubular body being radially self-expandable from a compressed configuration to an expanded configuration, the tubular body having a proximal end and a distal end and defining a lumen about a longitudinal axis, the tubular body comprising a proximal portion, a distal portion, and an intermediate portion, the proximal and distal portions each comprising at least one end cell comprising a plurality of struts and bends interconnected to the struts, and the intermediate portion comprising at least two or more intermediate cells comprising a plurality of struts and bends interconnected to the struts; wherein a first intermediate cell located adjacent the proximal portion and a second intermediate cell located adjacent the distal portion comprises integral barbs directed away from the proximal and distal portions respectively, the barbs being located at the bends interconnecting the struts, and the struts connected to the barbs being deflected radially outward from an outer circumference of the tubular body in the expanded configuration; characterised in that each of the struts connected to the barbs comprises a first portion located away from the barbs and a second portion located adjacent the barbs, the first portion not being deflected radially outward and being disposed within the outer circumference of the tubular body and the second portion being deflected radially outward of the outer circumference of the tubular body, the first portion being 25% to 50% of the entire length of each strut; and a graft attached to at least a portion of the intermediate portion. a tubular body being radially self-expandable from a compressed configuration to an expanded configuration, the tubular body having a proximal end and a distal end and defining a lumen about a longitudinal axis, the tubular body comprising a proximal portion, a distal portion, and an intermediate portion, the proximal and distal portions each comprising at least one end cell comprising a plurality of struts and bends interconnected to the struts, and the intermediate portion comprising at least two or more intermediate cells comprising a plurality of struts and bends interconnected to the struts; wherein a first intermediate cell located adjacent the proximal portion and a second intermediate cell located adjacent the distal portion comprises integral barbs directed away from the proximal and distal portions respectively, the barbs being located at the bends interconnecting the struts, and the struts connected to the barbs being deflected radially outward from an outer circumference of the tubular body in the expanded configuration; characterised in that each of the struts connected to the barbs comprises a first portion located away from the barbs and a second portion located adjacent the barbs, the first portion not being deflected radially outward and being disposed within the outer circumference of the tubular body and the second portion being deflected radially outward of the outer circumference of the tubular body, the first portion being 25% to 50% of the entire length of each strut; and a graft attached to at least a portion of the intermediate portion.
