Abstract: Leads for use with implantable medical devices are provided. One microlead is intended to be implanted in the venous, arterial, or lymphatic networks. Its diameter may be at most equal to 1.5 French (0.5 mm), and it may include a plurality of micro-cables each including: an electrically conductive core cable for connection to one pole of a multipolar generator of an active implantable medical device, and a polymer insulation layer surrounding the core cable. At least one exposed area may be formed in the insulation layer to form a detection/stimulation electrode.

Abstract: A method for constructing a plug for an electrical connection to a multipolar lead for an active implantable medical device includes providing a plug body having an insulating monobloc central core, the monobloc central core having a generally cylindrical shape, a cylindrical side surface, and a housing, providing a connection wire and a conductive pod, attaching the connection wire to the conductive pod, placing the conductive pod into the housing with connection wire extending therefrom, placing a conductive cylindrical ring on the cylindrical side surface, wherein the cylindrical side surface centers the conductive cylindrical ring coaxially about the monobloc central core, attaching the conductive pod to the cylindrical ring to create an electrical contact zone on a cylindrical outer surface of the plug body.

Abstract: An intracorporeal autonomous active medical device having a capsule body and a base. The capsule body includes a body portion and a lid portion, and the capsule body contains therein electronic circuitry containing the active elements of the autonomous medical device, and a power supply. The capsule body also includes a fastening system on an exterior surface of the capsule body that is configured to correspond with a fastening mechanism on the base configured to be anchored to a tissue wall. The fastening mechanism provides selective engagement between the capsule body and the base.

Abstract: An electrical connection plug for a multipolar lead of an active implantable medical device. This plug has a cylindrical outer surface including a plurality of annular electrical contact zones axially separated and formed of conductive cylindrical rings (101, 102, 103), the electrical contact zones being alternatively separated by a plurality of intercalary insulating cylindrical zones. The plug includes an insulating monobloc core (200) of a generally cylindrical shape having a plurality of cylindrical side surfaces (213a) for coaxial centering, a conductive ring being placed on at least one centering side surface. The central core also includes housings for receiving conductive pods (240) on which connection wires (21, 22) are welded, a pod being welded to a conductive ring.

Abstract: This implantable microcatheter includes a hollow tube with a central lumen extending throughout the length of the tube from a proximal region to a distal region. The bending stiffness of the proximal region is greater than the bending stiffness of the distal region, and the tube has a transition region having a decreasing stiffness gradient from the proximal region to the distal region. The tube wall is free of shielding or armor at least in the distal region, and the catheter is made of biocompatible material(s) suitable for a permanent implantation in venous, arterial or lymphatic networks.

Abstract: A leadless autonomous intracardiac implantable medical device having a releasable fastener system. This autonomous intracorporeal active medical device has two distinct elements connectable together and reversibly separable from one another, with a sealed capsule body (100) housing electronic circuitry (110), and a base (200) comprising a plate (202) having an outer face and an anchoring system on said outer face to anchor the base to a wall of an organ of a patient, and an inner face forming a support for the capsule body and having a fastening system to couple releasably the capsule body to the base. The capsule body comprises on its face turned towards the base at least one projection support (108) on an electrode surface for coming into contact with the wall of the organ of the patient when the capsule body is mounted on the base.
