Abstract
A bifurcated graft is formed from a series of individual components which are intraluminally delivered apart from one another and then assembled to form a fully supported structure. The modular system includes a base member and one or more grafts connected thereto. The base member preferably includes a portion which gradually increases in diameter. A tubular device for inserting the components of the modular system and a method employing the modular system for repairing an abdominal aortic aneurysm are also disclosed.
Claims20
A modular prosthesis for repairing an aortic aneurysm in an aorta extending from a heart of a patient, comprising:
- a base member foldable radially between a collapsed configuration and an expanded configuration and extending longitudinally between a proximal end and a distal end, said base member having a single inlet at said proximal end;
- a primary tubular limb foldable radially between a collapsed configuration and an expanded configuration and having a proximal end and a distal end, said primary limb having a single inlet at said proximal end and a single outlet at said distal end, said primary limb being formed separately from said base member and being adapted to lie in the aorta with said proximal end pointing toward the heart and sized to fit a diameter of the aorta;
- each of said base member and said primary limb including a flexible layer and an expandable stent radially supporting said flexible layer along substantially the entire length thereof;
- and
- joining means for intraluminally joining said distal end of said primary limb to said proximal end of said base member.

- each of said base member and said primary limb including a flexible layer and an expandable stent radially supporting said flexible layer along substantially the entire length thereof;
- at least one secondary tubular limb foldable radially between a collapsed configuration and an expanded configuration and having a proximal end and a distal end, said secondary tubular limb including a flexible layer and an expandable stent radially supporting said flexible layer along substantially the entire length thereof;
- and
- connecting means for connecting said proximal end of said secondary limb to said distal end of said base member.
