Patent ID: 8617159

Claim:
Instrumentation for performing an endoluminal or transluminal anastomosis, such as in a gastro-jejunostomy, in a jejuno-jejunostomy, in a colo-proctostomy, in a jejuno-colostomy or anastomoses of the chole duct, comprising: an anastomotic ring device including a proximal ring ( 5 ) having two guide wire seats ( 22 ) each of which is adapted to slidably receive one ( 1 ; 2 ) of two guide wires ( 1 , 2 ), respectively, and a distal ring ( 6 ) having two guide wire seats ( 25 ) each of which is adapted to slidably receive one ( 1 ; 2 ) of said two guide wires ( 1 , 2 ), respectively, the proximal ring ( 5 ) and the distal ring ( 6 ) being snap-connectable to each other, a surgical probe ( 7 ) comprising an elongate insertion shaft ( 30 ) and a probe head ( 32 ) distally connected to the insertion shaft ( 30 ) and adapted to be endoluminally advanced to a proximal tissue portion ( 3 ), said insertion shaft ( 30 ) defining guide wire canals ( 8 , 9 ) extending into two guide wire exit openings ( 31 ) defined in the probe head ( 32 ) and adapted to deliver the distal ends ( 1 â€³, 2 â€³) of said guide wires ( 1 , 2 ) to said proximal tissue portion ( 3 ), characterized in that the distance between said two guide wire exit openings ( 31 ) of the probe ( 7 ) is substantially equal to the distance between said two guide wire seats ( 22 ) of the proximal ring ( 5 ) and to the distance between said two guide wire seats ( 25 ) of the distal ring ( 6 ).
