Intracardiac capsule implantable on a thin wall, including the septum wall
First Claim
1. An intracardiac capsule, comprising:
- a cylindrical body having a distal end, a proximal end, and a contact region; and
a helical anchoring screw surrounding at least a portion of a length of the cylindrical body, the helical anchoring screw including a free distal end and a proximal end coupled to the cylindrical body;
wherein the contact region of the cylindrical body is disposed between the proximal end of the helical anchoring screw and the free distal end of the helical anchoring screw; and
wherein a gap is formed between an inner diameter of the helical anchoring screw and an outer diameter of the cylindrical body in the contact region.

Abstract
An intracardiac capsule comprises a cylindrical body having an atraumatic rounded surface and a helical anchoring screw integral with the cylindrical body. The helical anchoring screw is able to penetrate tissue of a wall of the heart and is configured to provide temporary attachment, in rotation and in translation, of the capsule to an implantation site. The helical anchoring screw surrounds at least a portion of the length of the cylindrical body forming a contact region intended to come into contact with the wall of the cavity of the heart. 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 there between. The helical anchoring screw is secured to the cylindrical body near the proximal end of the contact region, and extends freely to the opposite distal end.

11. A method of implanting an intracardiac capsule having a cylindrical body and a helical anchoring screw, a proximal end of the helical anchoring screw affixed to the cylindrical body, the helical anchoring screw surrounding at least portion of a total length of the cylindrical body, the method comprising:
-
positioning a distal end of the cylindrical body against a tissue wall to form an acute angle with the tissue wall such that a free distal end of the helical screw engages the tissue wall; and rotating the intracardiac capsule to cause progression of the helical screw in the tissue wall such that an axis of the cylindrical body is substantially parallel to the tissue wall after several rotations of the intracardiac capsule. - View Dependent Claims (12, 13, 14, 15, 16)

17. An intracardiac capsule, comprising:
-
a cylindrical body having a distal end, a proximal end, and a contact region, the contact region comprising from twenty (20) percent to eighty (80) percent of a total length of the cylindrical body; and a helical anchoring screw surrounding at least a portion of the total length of the cylindrical body including the contact region, the helical anchoring screw including a proximal end of the helical screw coupled to the cylindrical body and a free distal end of the helical anchoring screw; wherein the contact region of the cylindrical body is disposed between the proximal end of the helical anchoring screw and the free distal end; and wherein a gap is formed between an inner diameter of the helical anchoring screw and the outer diameter of the cylindrical body in the contact region. - View Dependent Claims (18, 19, 20)
