Abstract
A low profile stent graft for treatment of vascular abnormalities such as aneurysms. The endoskeleton of the stent graft has first and second self-expandable stents. The stents are spaced apart and connected together by at least one, and preferably three, flexible strut members. A tubular graft is placed around the endoskeleton while the stents are in a partially compressed state, and attached to the stents. A bifurcated configuration is disclosed that can be employed where the stent graft is to be used for repair of an aneurysm of the abdominal aorta.
Claims11
A stent graft for the treatment of vascular abnormalities comprising:
- a first self-expandable stent;
- a second self-expandable stent, said second stent being spaced from said first stent;
- each of said first and second self-expandable stents including a plurality of arms and inner and outer elbows joining said arms to thereby form a sinusoidal configuration;
- at least one strut member having first and second outer ends, said strut member being attached at its first outer end to an outer elbow of said first stent and attached at its second outer end to an outer elbow of said second stent;
- and
- a tubular graft extending between said first and second stents.
An endoskeleton for a stent graft used for the treatment of vascular abnormalities comprising:
- a first self-expandable stent;
- a second self-expandable stent, said second stent being spaced from said first stent;
- each of said first and second self-expandable stents including a plurality of arms and inner and outer elbows joining said arms to thereby form a sinusoidal configuration;
- at least one strut member having first and second outer ends, said strut member being attached at its first outer end to an outer elbow of said first stent and attached at its second outer end to an outer elbow of said second stent.
