Modular grafting system and method

Abstract

A system and method for treating and repairing complex anatomy characterized by a plurality of vessel portions oriented at various angles relative to each other. The system including a graft device that is capable of being assembled in situ and has associated therewith a method that avoids the cessation of blood flow to vital organs. A delivery catheter system and various graft supporting, mating and anchoring structures are additionally included.

1 . A system for treating vasculature, comprising:
 a main component having at least four apertures and at least two branch portions that each have one of the apertures oriented in a substantially reverse direction from an adjacent aperture at one end of the main component; and   at least two extension components each of which including a portion configured to sealingly engage with one of the apertures oriented in the substantially reverse direction.   
     
     
         2 . The system of  claim 1 , wherein the main component has five apertures. 
     
     
         3 . The system of  claim 1 , the main component further comprising an anchoring device attached to a superior end thereof, the anchoring device comprising a generally sinusoidal frame and at least one wall engaging member attached to the frame. 
     
     
         4 . The system of  claim 1 , the main component further comprising an anchoring device attached to an inferior end. 
     
     
         5 . The system of  claim 1 , wherein the main component has a generally tubular configuration with a superior end, a midsection and an inferior end, a first aperture of the at least four apertures positioned at the superior end, and a second aperture of the at least four apertures positioned at the inferior end. 
     
     
         6 . The system of  claim 5 , wherein the midsection of the main component has a circumference which is less than a circumference of each of the superior and inferior ends. 
     
     
         7 . The system of  claim 5 , wherein the superior and inferior ends have different circumferences. 
     
     
         8 . The system of  claim 5 , further comprising an inferior extension component. 
     
     
         9 . The system of  claim 9 , the inferior end further comprising a mating structure for mating with the inferior extension component. 
     
     
         10 . The system of  claim 9 , the mating structure further comprising a suture routed about an interior circumference of the inferior end. 
     
     
         11 . The system of  claim 8 , the inferior extension component further including a support structure extending a length thereof. 
     
     
         12 . The system of  claim 8 , the inferior extension component further comprising a first end, a second end and an anchoring device attached to the second end. 
     
     
         13 . The system of  claim 8 , the inferior extension component further comprising a complimentary mating structure that engages a mating structure of the main component. 
     
     
         14 . A system for treating vasculature, comprising:
 a main component including a superior end, an inferior end, and a midsection including at least three limbs oriented in a substantially reverse direction from the superior end or the inferior end, wherein each of the superior and inferior ends and the limbs include an aperture; and   at least three limb extension components each of which are configured to mate with one limb.   
     
     
         15 . The system of  claim 14 , further comprising a series of delivery catheters configured to deliver the main component and limb extension components within vasculature. 
     
     
         16 . The system of  claim 15 , wherein the main component and limb extension components are assembled in situ. 
     
     
         17 . The system of  claim 16 , wherein the superior end includes structure that attaches within a first portion of a first vessel and the inferior end includes structure that attaches to a second portion of the first vessel. 
     
     
         18 . The system of  claim 17 , wherein each of the limb extension components include a mating end that engages an aperture of one midsection limb and a second end for attachment to a vessel in fluid communication with and extending at an angle from the first vessel. 
     
     
         19 . The system of  claim 17 , the main component further comprising a supporting structure extending a length thereof. 
     
     
         20 . The system of  claim 17 , the main component further comprising an anchoring element attached to one of the superior or inferior ends. 
     
     
         21 . The system of  claim 14 , further comprising an inferior end extender member configured to mate with the inferior end of the main component.
