The anchoring means includes a screw with a helix wire wound into a plurality of non-contiguous turns, the screw having a clamped end integral with the front face of the device body and a free end with a beveled end defined by at least one oblique surface.

Abstract: The capsule comprises a tubular body and a front-end unit with an helical screw for anchoring 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. A disengageable frictional coupling member allows this relative rotation when, for implantation, the tubular body receives an external rotational stress, and that until a predetermined limit torque triggering the disengagement. At explantation, this disengagement is prevented to allow a joint rotation of the tubular body and of the front-end unit and the unscrewing of the helical screw. It is provided for that purpose two conjugated plates facing each other, with flat surfaces such as circular sectors offset in opposite directions with respect to a radial reference plane, in such a way as to form steps providing an anti-disengagement abutment function.
