An electrode lead for the coronary sinus, with a lead body that has a distal section for insertion into the coronary sinus, and at least one electrode to make contact with body tissue, the at least one electrode being arranged on the distal section of the lead body. The electrode lead has a fixation device that can be extended out of the lead body to fix the electrode lead in a blood vessel.

Electrode lead with continuously variable fixation length

An electrode lead for the coronary sinus, having a lead body, which has a distal portion for insertion into the coronary sinus, and at least one electrode for contacting bodily tissue, wherein the at least one electrode is arranged on the distal portion of the lead body. The electrode lead, in order to fix the electrode lead in a blood vessel, has a fixing device, which is connected to a distal end of the lead body, wherein the fixing device is designed to be shortened incrementally or lengthened incrementally.

Electrode lead with variable, incrementally adjustable fixing length

A method for producing a plug, and to a plug. It is provided, in particular, that a plug connector and three plug contact rings are arranged in a casting mold, wherein the plug connector extends along a longitudinal axis and has a contact portion and a fastening portion connected integrally to the contact portion, and wherein a plug housing is formed by introducing a casting material into the casting mold so that the fastening portion is surrounded form-fittingly by the casting material and the contact portion protrudes out from the plug housing at a first end of the plug housing in the direction of the longitudinal axis.

Plug with an over-molded, non-rotatable plug connector and four connectors, in particular an IS4/DF4 plug

An elongated guide sheath for delivering at least one medical instrument to a body lumen. For reliable and cost effective implantation of an electrode at the AV septum the inventive guide sheath forms a first guiding sleeve and a second guiding sleeve at least partly separated by a shared wall section, wherein the longitudinal axis of the first guiding sleeve and the longitudinal axis of the second guiding sleeve run parallel to a longitudinal guide sheath axis, wherein the wall of the first guiding sleeve and/or of the second guiding sleeve each comprises a slit which runs along at least part of the length of the respective guiding sleeve. Further, a system including the above guide sheath, a first catheter and/or guide wire and a second catheter or electrode is proposed.

An implantable curved shaping part for externally shaping an implantable electrode line or a catheter, wherein the shaping part has a continuous first lumen to allow a portion of the electrode line or of the catheter to pass through, wherein the shaping part has an extruded tube formed from two materials, each coextruded over a predetermined wall segment, having different shrinkage behavior or has a portion of an extruded spiral tube, wherein one of the coextruded materials or the material of the spiral tube has a high Shore hardness, in particular, of 60 Shore or more.

Implantable curved shaping part for externally shaping an implantable electrode line or a catheter

An implantable curved shaping part for externally shaping an implantable electrode line or a catheter, wherein the shaping part has a continuous first lumen to allow a portion of the electrode line or of the catheter to pass through, wherein the shaping part is formed as an injection molded part or has at least one injection molded portion, and an elongated, rigid yet flexible bend impression element is fixed within the wall or to the inner wall.

A contacting device for electrical connections to flexible electrode lines insertable or implantable into a patient body, includes a line coil with a plurality of coradially bundled coil wires, an inner fixing sleeve for a partial bundle of the coil wires, the fixing sleeve has a through-slit running in the axial direction for the partial bundle of the coil wires, and a winding groove running in the peripheral direction for the partial bundle led through, an outer electrode sleeve sitting on the inner fixing sleeve and electrically contacted with the partial bundle, and a strain-resistant fixing between the fixing sleeve and the partial bundle guided through the through-slit via an application of force on the partial bundle by pressing the fixing sleeve onto the line coil to produce plastic deformation and by looping the led-out partial bundle around the fixing sleeve in the winding groove by a minimum looping angle.

Contacting device for electrical connections to flexible electrode lines

An electrode connection for an electrode catheter including an electrode, a line for electrical signals configured as a coil having an electrode end connected to the electrode, and a fixation device for the electrode end of the coil on the electrode, wherein the fixation device includes an inner sleeve, on which the electrode end of the coil sits, and a squeeze ring, which acts upon the electrode end of the coil, establishing an electrical contact with the electrode and mechanical clamping on the inner sleeve.

Electrode connection, in particular for an electrode catheter

An electrode catheter, in particular for cardiac therapy, includes an elongated, tube-type catheter body, a ring electrode before the distal end of the electrode catheter for delivery and/or measurement of an electrical signal, in particular an electrocardio signal, by way of the outer electrode contact surface thereof, and a supply lead for the electrical connection of the ring electrode. The ring electrode is mounted on the catheter body such that it can be displaced relative thereto in the longitudinal axial direction.

Electrode catheter, in particular for cardiac therapy

A conductive coil arrangement, in particular for electrode catheters for cardiac therapy, including a multipolar conductive coil having a plurality of coradially interwoven individual coil wires and a contact zone in which at least one individual coil wire from the conductive coil can be connected to a contact element for electrical contacting. The at least one individual coil wire to be contacted is routed outwardly out of the wire interconnection of the conductive coil with a radial direction component. The remainder of the conductive coil is routed further centrally axially through the contact zone.

Conductive coil arrangement and electrode catheter arrangement, in particular for cardiac therapy

An electrode catheter, in particular for cardiac therapy, includes an elongate, tubular catheter body, an electrode for delivering or measuring an electrical signal, in particular an electrocardiac signal, via its external electrode contact surface, at least one first supply line for the electrical connection of the electrode, at least one second supply line for the electrical connection of a further electrode, a plug terminal connection between the at least one first supply line and the electrode, and an insulated passage of the at least one second supply line through the electrode.

An active fixation cardiac electrode lead having a fixation helix movably placed in a housing at the electrode lead's distal end so as to be extended out of the housing's distal end and retraced into an inner space enclosed by the housing. The housing has a wall and a protrusion formed in the wall that protrudes into the inner space into interspaces between windings of the fixation helix. The protrusion causes an axial movement of the helix when the helix is rotated around its longitudinal axis. The protrusion is an integral part of the housing's wall which is bent or embossed to form the protrusion.
