Hybrid modular endovascular graft
First Claim
Patent Images
1. A hybrid modular endovascular graft system, comprising:
- a main graft having a main fluid flow lumen therein, a distal leg of the main graft having a fluid flow lumen therein, a proximal anchor member disposed at a proximal end of the main graft and a distal anchor member disposed on a distal portion of the distal leg, the distal anchor member being axially separated from the proximal anchor member by a length of about 12.0 cm to about 14.0 cm; and
a graft extension having a fluid flow lumen disposed therein with the fluid flow lumen of the graft extension sealed to and in fluid communication with the fluid flow lumen of the distal leg.

Abstract
A hybrid modular endovascular graft wherein a main graft is sized to span at least a portion of a target vessel lesion in a large percentage of patients. Graft extensions may be secured to the main graft to extend the main graft and provide a sealing function for some applications.

9. A method of treating the vasculature of a patient, comprising:
-
providing a graft system, comprising;
a main graft having a main fluid flow lumen therein, a distal leg having a fluid flow lumen therein, a proximal anchor member disposed at a proximal end of the main graft and a distal anchor member disposed on a distal portion of the distal leg, the distal anchor member being axially separated from the proximal anchor member by a distance of about 12.0 cm to about 14.0 cm, and a graft extension having a fluid flow lumen disposed therein with the fluid flow lumen of the graft extension sealable to the fluid flow lumen of the distal leg;
positioning the main graft within the patient'"'"'s vasculature and anchoring the proximal anchor member in the patient'"'"'s aorta and anchoring the distal anchor member in an iliac artery of the patient;
positioning the graft extension relative to the main graft such that the fluid flow lumen of the graft extension is sealed with the fluid flow lumen of the distal leg. - View Dependent Claims (10, 11, 12)

13. A hybrid endovascular graft, comprising:
a main graft having a main fluid flow lumen therein, a distal leg of the main graft having a fluid flow lumen therein, a proximal anchor member disposed at a proximal end of the main graft and a distal anchor member disposed on a distal portion of the distal leg, the distal anchor member being axially separated from the proximal anchor member by a length of about 11.0 cm to about 15.0 cm. - View Dependent Claims (14)

15. A method of sizing a main graft of a hybrid modular endovascular graft system, comprising:
-
selecting a group of patients to be treated;
sizing the axial separation of the proximal anchor member and ipsilateral distal anchor member of a main graft such that the axial separation is no shorter than the separation between the renal arteries and the proximal most anchor point in the iliac artery or arteries of a patient who has the longest such separation, and no longer than the separation between the renal arteries and hypogastric artery or arteries of a patient who has the shortest such separation. - View Dependent Claims (16, 17)
