Claim Text:
1. An intracardiac capsule, comprising: a cylindrical body comprising an atraumatic rounded surface; and a helical anchoring screw integral with the cylindrical body, able to penetrate tissue of a wall of a cavity of the heart and configured to provide temporary attachment, in rotation and in translation, of the capsule to an implantation site; wherein the helical anchoring screw surrounds at least a portion of the length of the cylindrical body forming a contact region along a circumferential region of the cylindrical body intended to come into contact with the wall of the cavity of the heart; wherein, over the length of the contact region, the external diameter of the cylindrical body is less than the inner diameter of the helical anchoring screw, so as to leave a free gap between the cylindrical body and the helical anchoring screw; wherein rotation of the helical anchoring screw threads at least two screw turns into a length of tissue such that the two screw turns press the contact region along the circumferential region of the cylindrical body against an external portion of the tissue surface parallel to the tissue surface.
