The invention refers to 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 (10, 60, 70) forms a first guiding sleeve (11, 61,71) and a second guiding sleeve (12, 62, 72) at least partly separated by a shared wall section (16, 66, 76), wherein the longitudinal axis of the first guiding sleeve (11, 61, 71) and the longitudinal axis of the second guiding sleeve (12, 62, 72) run parallel to a longitudinal guide sheath axis (14), wherein the wall of the first guiding sleeve (11, 61, 71) and/or of the second guiding sleeve (12, 62, 72) each comprises a slit (17, 18) which runs along at least part of the length of the respective guiding sleeve (11, 61, 71, 81, 12, 62, 72). Further, a system comprising the above guide sheath, a first catheter and/or guide wire and a second catheter or electrode is proposed. |
