Medical-grade actuator having a modular structure and medical device comprising same

Abstract

The present invention relates to an artificial contractile device comprising at least one contractile element () comprising a flexible strip () extending in a longitudinal direction and a closure () for forming the contractile element () into a closed loop around a hollow body organ, the closure () being situated at a first extremity of the flexible strip (). The contractile element is adapted to contract a hollow body organ, in such a way that said contractile element () may be in a resting position or in an activated position. The artificial contractile device further comprises a flexible transmission () comprising a tensioning element () being anchored at a first end () to a first anchoring point (A) on the flexible strip (), said flexible transmission () being adapted to tighten the contractile element () formed in a closed loop around said hollow body organ upon application of a traction force at and end of the tensioning element () by an actuator (). The artificial contractile device also comprises a connector () adapted to connect the flexible transmission () to a said actuator (), a second end () of said tensioning element () being anchored in said connector ().
