Patent ID: 7060080

Claim:
A surgical ring ( 1 ), designed to be implanted in the body of a patient around a biological organ to form a pouch or a duct, in order to modify the cross-sectional area of a passage of the organ when it is tightened by the ring, the ring ( 1 ) comprising: a flexible band ( 2 ), comprising first and second extremities ( 3 , 4 ), the flexible band ( 2 ) being designed to be closed near these two extremities ( 3 , 4 ) by a closure system to form a closed ring, the said closed ring having an internal contact surface ( 2 A) with the biological organ and an opposite external surface ( 2 B); and wherein the closure system comprises a means of encircling ( 5 ) united to the first extremity ( 3 ) and arranged to evolve between: a de-latching configuration where the means of encircling ( 5 ) forms an open collar freeing the second extremity ( 4 ); and a latching configuration where the means of encircling ( 5 ) forms a closed collar designed to surround the second extremity ( 4 ) so as to unite it with the first extremity ( 3 ), the closed collar presenting opposite front ( 6 ) and rear faces ( 7 ), between which an encircling opening extends, which is designed to accept the second extremity ( 4 ), wherein the means of encircling ( 5 ) further comprises a male element ( 8 ) and a female element ( 9 ), each of which is mounted integrally to the first extremity ( 3 ) and mounted on or relative to the latter in such a way that, when they are connected together, the means of encircling ( 5 ) is latched, forming the closed collar, and wherein the second extremity ( 4 ) of the ring ( 1 ) further comprises a first means of stopping ( 16 ) designed to thrust against the rear face ( 7 ) of the closed collar surrounding the second extremity ( 4 ) of the ring in latching configuration, so as to prevent the shifting of the second extremity ( 4 ) in the opening direction of the ring ( 1 ).
