## Abstract

A stent graft system includes a tubular graft component, a bare stent component, an infrarenal stent component at least one suprarenal barb extending distally from at least one suprarenal portion of the bare stent component and at least one infrarenal barb extending distally from at least one infrarenal portion of the bare stent component. A stent graft system can also include at least one barb.

## Claims

### Claim 1

A stent graft system, comprising:
a) a tubular graft component including a proximal end and a longitudinal axis;
b) a bare stent component including a plurality of struts joined by distal and proximal apices integral to and comprising ends of the struts, the bare stent component directly fixed at the distal apices to the proximal end of the tubular graft component, thereby defining an infrarenal portion of the bare stent component, the bare stent component extending proximally beyond the proximal end of the tubular graft component to thereby define a suprarenal portion of the bare stent component, wherein the suprarenal portion of the bare stent includes a bridge that spans the adjacent struts to define an eyelet, the eyelet defining a major plane;
c) an infrarenal stent component attached to the tubular graft component and adjacent to the bare stent component, wherein the infrarenal stent component is distal to proximal apices of the bare stent component and spans a circumferential line defined by the distal apices of the bare stent component fixed to the tubular graft component; and
d) at least one suprarenal barb attached to and extending distally from the bridge of the bare stent component, wherein the at least one suprarenal barb is angled from the major plane of the eyelet, whereby the adjacent struts are distended toward the longitudinal axis of the tubular graft component when the distal apices of the bare stent component are not in a captured state while the proximal apices of the bare stent component are in the captured state, wherein the suprarenal barb extends along the longitudinal axis of the tubular graft component.

### Claim 2 (depends on 1)

The stent graft system of claim 1, wherein at least one of the stents includes a superelastic metal.

### Claim 3 (depends on 1)

The stent graft system of claim 1, further including at least one infrarenal barb extending distally from at least one infrarenal portion of the bare stent component.

### Claim 4 (depends on 3)

The stent graft system of claim 3, wherein the at least one infrarenal barb extends from an apex that joins two struts.

### Claim 5 (depends on 4)

The stent graft system of claim 4, wherein the distance between the most proximal point of the at least one suprarenal barb and the at least one infrarenal barb is in a range of between about 6 mm and about 40 mm.

### Claim 6 (depends on 3)

The stent graft system of claim 3, wherein the distal apices of the bare stent are fixed within the tubular graft component, and wherein the at least one infrarenal barb extends from the bare stent through the tubular graft component.

### Claim 7 (depends on 3)

The stent graft system of claim 3, wherein the infrarenal stent is fixed within the tubular graft component.

### Claim 8 (depends on 1)

The stent graft system of claim 1, wherein the tubular graft component is bifurcated.

### Claim 9 (depends on 1)

The stent graft system of claim 1, wherein the at least one barb extends from a center portion of the bridge.

### Claim 10

A stent graft system, comprising:
a) a tubular graft component including a proximal end and a longitudinal axis;
b) a bare stent extending proximally beyond the proximal end of the tubular graft component to thereby define a suprarenal portion of the bare stent, the bare stent including struts, distal ends of which comprise distal apices that are integral to the struts and proximal ends of which comprise or adjoin proximal apices, and further including a bridge that spans adjacent struts at the proximal ends of the suprarenal portion to define eyelets at the proximal ends of the struts, the eyelet defining a major plane, and wherein the distal apices adjoining struts are fixed to the proximal end of the tubular graft component, thereby defining an infrarenal portion of the bare stent; and
c) at least one proximal barb attached to and extending distally from the bridge at the proximal apex of the bare stent, wherein the at least one proximal barb is angled from the major plane of the eyelet, whereby the adjacent struts are distended toward the longitudinal axis of the tubular graft component when the distal apices of the bare stent are not in a captured state and the proximal apices of the bare stent are in the captured state, wherein the proximal barb extends along the longitudinal axis of the tubular graft component.

### Claim 11 (depends on 10)

The stent graft system of claim 10, wherein the tubular graft component is bifurcated.

### Claim 12 (depends on 11)

The stent graft system of claim 11, wherein at least a portion of the at least one proximal barb extends from the major plane of the respective eyelet at an angle in a range of between about 20 degrees and about 60 degrees.

### Claim 13 (depends on 12)

The stent graft system of claim 12, wherein the bare stent is formed at least in part of a superelastic metal.

### Claim 14 (depends on 10)

The stent graft system of claim 10, wherein the at least one barb extends from a center portion of the bridge.
