Abstract
The capsule includes a tubular body and a front-end unit including an anchoring member for the anchoring of the capsule to a wall of a patient's organ. The front-end unit is mobile in relative axial rotation with respect to the tubular body, and a disengageable coupling member is adapted to allow this relative rotation when the tubular body receives an external rotational stress, the anchoring member then exerting a reaction torque higher than a predetermined threshold torque, and to prevent the relative rotation in the absence of external rotational stress applied to the tubular body. The coupling member may in particular include, between the front-end unit and the tubular body, a friction interface, with an elastically deformable element applying an axial compression between a bearing face of the tubular body and a support ring integral with the anchoring member.
