1. An artificial contractile structure for a medical device, said artificial contractile structure comprising:
an elongated member adapted to contact a hollow body organ, said elongated member comprising an elongated body extending a longitudinal direction between a first and a second end, the first and second end being arranged at a distance of one another on a first and second extremity, respectively, of the elongated member;
a tension system arranged to be connected to a control unit, said tension system being adapted bring said first and second ends of the elongated body closer together in response to a force applied by said control unit, so as to constrict the hollow body organ;
wherein said elongated member comprises a resilient core and a biocompatible outer sheath, and said tension system comprises a first tensile element attached to said first end of said elongated member, and a second tensile element attached to said second end of said elongated member, each of said tensile elements passing through an adaptor situated between said first end and said second end.
