Embodiment Construction

[0036] figure 1 is a schematic cross-sectional view of a myocardium 10 with a right ventricle 12 and a left ventricle 14 separated by a septum 16 . Its general thickness is about 10 to 15 mm and constitutes a significant portion of the heart's mass.

[0037] Depolarization waves originating from the sinoatrial node 18 are transmitted to the atrioventricular node 20 and the bundle of His 22, which divides into two branches extending along the septum 16, a straight branch in the region of the right septal wall 26 24 and the left branch 28 in the region of the left septum 30 .

[0038] In particular, the left branch 28 is a fast longitudinal conductive wire (arrow 32 ) with a speed of about 4 m / s. However, conventional techniques for implementing telescoping helical leads can stimulate the right wall 26, so in order to stimulate the left ventricle 14, the depolarization wave must pass through the septum 16 (arrow 34), but the velocity of the transconduction is relatively low, a...

Abstract

The lead has a body (42) with an isolated flexible hollow sheath (44). The body is arranged with an internal driver (46), and an electric connector (60) having a central pin (58) that is connected to the driver. A guidance core (62) is arranged for driving and guiding of a stimulation needle (54) into rotational and translational movement inside a tubular body (48). A set of coupling units such as external thread (64) and internal thread (66), is ready to transform a rotation movement of the core with regard to the body into an axial translatory movement of the core inside the body.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of French Patent Application No. 1259760, filed October 12, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to intracardiac leads for left ventricular pacing. The present invention is within the general context of "active / active implantable medical devices" defined by Council Directive 90 / 385 / EEC of 20 June 1990, comprising implants for continuous monitoring of heart rhythm and according to Need to deliver electrical stimulation, resynchronization or defibrillation pulses to the heart. Background technique [0004] Intracardiac "stimulation" leads are those used to deliver low energy pulses for bradycardia or resynchronization therapy. The invention also applies to intracardiac leads used for cardioversion / defibrillation intended to deliver high energy shocks to the heart in an attempt to terminate...
