The present invention relates to an implantable lead comprising at least one conductive wire and one electrical connector, the electrical connector configured to be connected to an implantable medical device such as a cardiac stimulation, defibrillation and/or neuromodulation device, wherein the electrical connection between the conductive wire and the connector is effected by a first hypotube welded to the conductive wire and welded to a second hypotube of the electrical connector. The present invention also relates to a method for electrically connecting the at least one conductive wire of the implantable lead to the electrical connector.

Implantable lead

Leads for use with implantable medical devices may be implanted in the venous, arterial, or lymphatic networks. The diameter of a microlead 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.

Implantable detection/stimulation multipolor microlead

The present invention relates to an implantable lead comprising at least one conductive wire and a connector. The connector is configured to be connected to an implantable medical device, such as a cardiac stimulation, a defibrillation or/and a neuromodulation device, and further comprising a strain relief device extending longitudinally along an axis from one end of the connector and essentially parallel to the longitudinal axis of the connector. The conductive wire is deflected by a deflection wall of the strain relief device such that the deflection wall of the strain relief device blocks the conductive wire against the deflection wall when the conductive wire is stressed in tension, and the deflection wall extends along an axis which is misaligned with the longitudinal axis of the strain relief device.

Implantable medical lead with strain relief device

This system includes a conductor microcable and an insulating microcatheter, including a hollow tube housing the microcable with the possibility of relative axial translation therebetween. The microcatheter is suitable for permanent implantation. The microcatheter, in its distal portion, includes at least one lateral window formed by a through orifice formed on the wall of the hollow tube. The window forms a stimulation site defined on the wall of the target vein facing the window of the microcatheter, and provides for a region of the microcable surface located at the window to form a stimulation electrode. In its distal portion, the microcable is not isolated at least in the region of the window of the microcatheter. The microcatheter is telescopically moveable on the microcable, so as to modify the position of the stimulation site of the target vein.

System implantable into the coronary venous network for the stimulation of a cardiac left cavity

The present invention relates to a method for connecting a strand of a multi-strand cable to an electrode of an implantable medical device. The method includes cutting a strand of the multi-strand cable lifting at least one of the free ends, stripping the end of the lifted strand, placing an electrode around the multi-strand cable to partially cover the end of the lifted and stripped stand, and connecting at least one portion of the stripped end of the strand to the electrode.

Connection method for connecting an isolated micro-conductor

The disclosure relates to a method of manufacturing an implantable defibrillation coil for a lead of an active implantable medical device, the defibrillating coil includes at least one elongate conductive coil which includes a plurality of non-contiguous turns. The method includes inserting a tube of polymeric material within the elongated conductive coil, supplying thermal energy to soften the tube, applying pressure on the assembly formed by the elongate conductive coil and causing the tube to deform the tube wall by insertion of the tube wall between the turns of the elongate conductive coil.

A metal ring for installation as an electrode on a microcable includes an elongated ring having an internal lumen, a middle portion partially collapsed into the internal lumen and adapted to puncture a sheath of the microcable when the middle portion is crimped around the microcable, and two end portions surrounding the middle portion.

Cardiac or cerebral vessel microlead with electrode ring

An explantation accessory includes a catheter with a steerable head carrying a tubular receptacle adapted to accommodate the proximal portion of the capsule. The explantation accessory further includes a lasso having a flexible wire extending along the catheter to and forming at its distal end a deformable loop. One end of the deformable loop is mobile so as to allow tightening of the loop under the effect of a traction exerted on the flexible wire along the catheter. The free end edge of the tubular receptacle comprises a protruding anterior portion, an axially recessed posterior portion with respect to the anterior portion and located diametrically opposite to the protruding anterior portion, and two beveled edges connecting the protruding anterior portion to the recessed posterior portion.

Explantation accessory for an intracorporeal capsule

The disclosure relates to a lead including a connector for connection to a generator, a demultiplexing circuit receiving at its input on the first conductors of the electrical control signals from the control bus and whose output is connected to a plurality of second conductors contained in the lead and connected to the lead electrodes. The lead further includes a gate and connection circuit component having a body forming a support for an integrated circuit for demultiplexing and defining a set of connection cavities with the second conductor distributed at the periphery of the body around a general axis of the body, and a plurality of connecting elements embedded in the body material, and emerging at an element region and supporting the circuit at respective cavities. The gate and connection circuit component is advantageously made of ceramic-metal.

Multielectrode lead with multiplexed control and associated connection method

A microlead, of an overall diameter less than 0.5 mm, includes a plurality of at least eight conductor wires individually insulated and twisted together. Each conductor wire includes an electrically conductive core microcable and an insulation layer surrounding the core microcable and having at least one exposed area to form a detection/stimulation electrode of the microlead. The microlead further includes a central support structure shaped as a surface of revolution, which may be free of conductor wires and of central lumen. The conductor wires are configured in one or more layers of twisted peripheral conductor wires carried by the central support structure and circumferentially distributed thereon.

A method of manufacturing a detection/stimulation lead for implantation into a venous, arterial, or lymphatic network is shown and described. The method includes providing a microcable comprising a sheath of insulating material covering an electrically conductive core. The method further includes surrounding a portion of the microcable with an electrically conductive metal ring. The method also includes crimping the ring such that the thickness of the sheath is penetrated by a portion of the metal ring and such that an electrical connection is formed between the metal ring and the electrically conductive core.
