The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ. The contractile element further includes a closure for forming the contractile element into a closed loop around said hollow body organ, the closure having a plurality of lips arranged to engage the contractile element. ## Claims ### Claim at position 1 1-29. (canceled) ### Claim 30 A medical device comprising: an artificial contractile structure comprising at least one contractile element adapted to contract a hollow body organ, such that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with said contractile element constricting the hollow body organ and the resting position being defined with said contractile element not constricting the hollow body organ; a tensioning device adapted to apply a force so as to tighten the contractile element around said hollow body organ, wherein the contractile element further comprises a closure for forming the contractile element into a closed loop around said hollow body organ, the closure comprising a plurality of lips arranged to engage the contractile element. ### Claim 31 (depends on 30) The medical device according to claim 30, wherein the closure is arranged so as to form the contractile element into a closed loop having one of a plurality of predetermined circumferences. ### Claim 32 (depends on 30) The medical device according to claim 30, wherein the contractile element further comprises: a flexible strip extending in a longitudinal direction; a plurality of transversal reinforcement elements extending from a surface of the flexible strip, and wherein the closure being situated at a first extremity of the flexible strip and arranged to engage the flexible strip. ### Claim 33 (depends on 30) The medical device according to claim 30, wherein the plurality of lips overhang a transverse connecting member. ### Claim 34 (depends on 32) The medical device according to claim 32, wherein the closure is arranged to be closed at one of a plurality of predetermined positions along said flexible strip. ### Claim 35 (depends on 32) The medical device according to claim 32, wherein said plurality of lips extend towards each other from the edges of flexible strip and are adapted to embrace flexible strip, together with one or more transversal reinforcement elements. ### Claim 36 (depends on 30) The medical device according to claim 30, wherein said closure comprises a security device arranged to secure the lips in position. ### Claim 37 (depends on 36) The medical device according to claim 36, wherein the security device comprises a plurality of mutually interlocking flaps. ### Claim 38 (depends on 36) The medical device according to claim 36, wherein the security device comprises a pair of mutually interlocking flaps, a first of the pair of flaps being configured to pass through an opening of a second of the pair of flaps. ### Claim 39 (depends on 38) The medical device according to claim 38, wherein flaps comprise tabs. ### Claim 40 (depends on 38) The medical device according to claim 38, wherein the second flap is provided with a root portion adjacent to the corresponding lip, a connecting element connecting the root portion to a further tab, situated in a different plane to the root portion. ### Claim 41 (depends on 40) The medical device according to claim 40, wherein the connecting element is configured to pass through the opening, such as the tabs point in opposite directions.
