Patent ID: 7922733

Claim:
A device for end-to-side anastomosis of body ducts comprising: a coupling ( 2 ) which can be positioned on a side wall ( 3 a ) of a first duct ( 3 ) and connectable to a second duct ( 4 ) in order to create a fluid communication between the first ( 3 ) and second duct ( 4 ), wherein said coupling ( 2 ) comprises a saddle-shaped portion ( 7 ) which can at least partially overlap the side wall ( 3 a ) of said first duct ( 3 ) and including an opening ( 8 ) to create a fluid communication between said first ( 3 ) and said second duct ( 4 ); means of restraint ( 5 ) for attaching the coupling ( 2 ) to said first duct ( 3 ), wherein the means of restraint ( 5 ) act with a clamping movement for anchoring to the wall ( 3 a ), said means of restraint ( 5 ) comprising at least two elements ( 9 , 10 ) that are elastically deformable so as to at least partially encircle said first duct ( 3 ) and to attach said coupling ( 2 ) to said first duct ( 3 ), wherein each elastically deformable element ( 9 , 10 ) comprises a fastener ( 11 ) for attaching the coupling ( 2 ) to said first duct ( 3 ), each said fastener ( 11 ) comprising at least one hook ( 12 ) to only partially perforate the side wall ( 3 a ) of the first duct ( 3 ) and attach itself to the side wall ( 3 a ) of said first duct ( 3 ).
