Anastomosis system and method
First Claim
1. A docking head to be mounted on a graft having an outer diameter so as to couple the graft to a blood vessel, said docking head comprising a hollow truncated cone having a passage that is adapted to correspond the outer diameter of the graft and wherein said hollow truncated cone is provided with a plurality of outwardly pointing and inclined barbs, whereby the docking head act as guiding, anchoring and sealing means in its coupling to the graft.

Abstract
The present invention provides docking heads to be mounted on a graft so as to establish a vascular device that is coupled to a blood vessel with aneurysm, and dedicated delivery devices as well as methods of coupling. The vascular device comprises a graft having docking head at the proximal portion and another docking head at its distal portion, or two docking heads if the graft is bifurcated. The docking heads comprises a hollow truncated cone having a passage adapted to correspond the outer diameter of the graft and is provided with a plurality of outwardly pointing and inclined barbs. The vascular device is coupled to the blood vessel on both sides of the aneurysm while the docking heads act as guiding, anchoring and sealing means in a suture-less and rapid manner. The vascular device is modular and can be prepared according to the condition of the aneurysm and the dimensions of the blood vessels during operation.

11. A vascular device for treating a blood vessel with aneurysm comprising:
-
a graft having a proximal portion and a distal portion;
at least two docking heads wherein a first docking head is provided at said proximal portion and at least one second docking head is provided at said distal portion;
whereby the vascular device is coupled to the blood vessel on both sides of the aneurysm by said at least two docking heads that act as guiding, anchoring and sealing means in a suture-less and rapid manner. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A delivery device adapted to facilitate the insertion of a vascular device for treating a blood vessel with aneurysm that comprises a graft having a proximal portion and a distal portion and at least two docking heads wherein a first docking head is provided at said proximal portion and at least one second docking head is provided at said distal portion, said delivery device comprising:
-
a flexible tube having a proximal side and a distal side;
a wire passing through said flexible tube, wherein said wire extends beyond said distal side so as to enable its removal from said flexible tube;
a sharp tip provided on said wire wherein said sharp tip is adapted to protrude through said proximal side and wherein said sharp tip can be withdrawn inwardly to within said flexible tube;
an inflatable balloon provided in said proximal side;
a tubing extending from said inflatable balloon to said proximal side, wherein liquid can be pushed through said tubing so as to inflate said inflatable balloon up to blood flow stoppage. - View Dependent Claims (30)

31. An anastomosis method for treating a blood vessel having an aneurysm edged by healthy portions:
- a proximal healthy portion and a distal healthy portion, said method comprising;
providing a graft having a length and a diameter corresponding the blood vessel to be treated, wherein said graft has a distal end and a proximal end and wherein said graft is provided with at least two docking heads that comprise a hollow truncated cone having a passage that is adapted to correspond an outer diameter of the graft and wherein said hollow truncated cone is provided with a plurality of outwardly pointing and inclined barbs, wherein a first docking heads is provided in said proximal end and at least second docking head is provided in said distal end;
providing a delivery tool;
stopping blood flow in the blood vessel;
performing an incision and cleaning the aneurysm;
inserting said proximal end to the proximal healthy portion;
slightly pulling backwardly proximal end so as to dock said first docking head in the proximal healthy portion;
inserting said distal end to the distal healthy portion;
slightly pulling backwardly distal end so as to dock said at least one second docking head in the distal healthy portion;
restoring the blood flow;
suturing the incision. - View Dependent Claims (32, 33, 34, 35, 36)
