Abstract:
Means for creating a vascular graft network for surgical implantation for creating bypass blood flow in coronary arteries, and adapted to be received within the vascular system of the patient; said means comprising:(a) a first and a second stented graft;(b) said first stented graft comprising a stent body with a pair of spaced-apart tubular elements, each having a distinct lumen formed therewithin and including one of a blood supply lumen or a delivery lumen, and with a cross-over lumen extending therebetween and providing for blood flow from said supply lumen to said blood delivery lumen;(c) said supply lumen having opposed proximal and distal graft link receiving blood flow ends, and with said proximal blood flow end having a graft link secured and affixed thereto, with said graft link being adapted to form a portion of said vascular graft network;(d) said delivery lumen being configured for direct implantation into a selected coronary artery at a location for delivering bypass blood flow from said supply lumen into said selected coronary artery; and(e) the opposed ends of said delivery lumen being axially offset from the opposed flow ends of said supply lumen, and with the distal end of said supply lumen extending axially beyond the adjacent end of said delivery lumen;(f) said second stented graft comprising a stent body having a graft link secured to the proximal end and adapted to receive a flow of blood from said first stented graft, said second stented graft adapted for application as a terminal device for said vascular graft network, and having means thereon for surgically joining the distal end of said second stented graft to the patient's vasculature system.
