Abstract
A bifurcated vascular graft having a tubular trunk with an inner diameter. Tubular limbs having respective inner diameters extend longitudinally from the trunk, and the diameter of at least one of the limbs is unequal to half the trunk diameter. In one embodiment, the graft is flared such that the combined diameters of the limbs exceed the diameter of the trunk. In another embodiment, the graft is tapered such that the diameter of the trunk exceeds the combined diameters of the limbs. In a third embodiment, the limb diameters are unequal to one another.
Claims33
A unibody bifurcated vascular graft comprising:
- a tubular trunk having a diameter;
- a first tubular limb extending from the trunk and having a first limb diameter that is larger or smaller than one-half the trunk diameter;
- and
- a second tubular limb extending from the trunk and having a second limb diameter;
- wherein the sum of the first and second limb diameters is larger than the trunk diameter.
A method of endovascularly implanting a unibody vascular graft into vessels of a patient, comprising the steps of:
- providing a selection of unibody bifurcated vascular grafts each having:
- a tubular trunk having a selected diameter;
- a first tubular limb extending from the trunk and having a first limb diameter that is larger or smaller than one-half the trunk diameter;
- and
- a second tubular limb extending from the trunk and having a second limb diameter;
- in which, in the selected vascular graft, the sum of the first and second limb diameters is greater than the trunk diameter;
- measuring the vessels of the patient requiring implantation;
- and
- endovascularly implanting a selected vascular graft into the patient's vessel.
