Patent ID: 8147501

Claim:
An anastomosis method for treating a vessel having an aneurysmal or occlusive disease edged by a proximal portion and a distal portion, wherein the portions are suitable for anastomosis, said method comprising: preparing a vascular graft to a length and a diameter corresponding to dimensions of the proximal and distal portions of the vessel, wherein said vascular graft has at least one distal end and a proximal end; choosing during the operation which docking head suits an inner dimension of the vessel being treated based upon a size of the inner dimensions; connecting at least two chosen docking heads, wherein each docking head comprises thin-walled hollow truncated head having a passage that fits an outer diameter of the vascular graft wherein said hollow truncated head and a portion of each docking head is provided with a plurality of outwardly pointing and inclined barbs and the barbed portion is non-expandable, wherein a first docking head is connected to said proximal end and at least one second docking head is connected to said distal end; providing a delivery tool; stopping flow of blood in the vessel in the proximal portion and the distal portion; performing an incision at a diseased portion of the vessel between the proximal portion and the distal portion and cleaning it; inserting through said incision said proximal end to the proximal portion manually or by a delivery tool; slightly pulling backwardly said proximal end so as to dock said first docking head in the proximal portion; inserting through said incision said distal end to at least on said distal portion manually or by a delivery tool; restoring the fluid flow; and suturing the incision.
