    • An insertion device (10), by which a medical instrument or an electrode line or a guide wire or a medical therapeutic agent may be inserted into a body cavity, comprises a lumen section (11) manufactured from a flexible plastic material, having a longitudinal axis, a proximal end and a distal end, and a distal end area enclosing the distal end, at least one electrically conductive means (20) in the distal end area to sense physiological signals or stimulate the surrounding body tissue suitably, as well as at least one conductor, which extends from the proximal end to the distal end and is capable of conducting physiological signals to the proximal end and/or stimulation pulses to the distal end. The at least one electrically conductive means is produced from a flexible, not exclusively metallic, electrically conductive substrate.

    • Apparatus are provided for performing a procedure within a patient's body that include a tubular member including proximal and distal ends, a central axis or region extending therebetween, and a distal portion extending distally from an intermediate portion to the distal end. One or more accessory lumens and a steering element lumen extend between the proximal and distal ends, the steering element lumen offset from the central region within the distal portion such that a steering plane intersects the steering element lumen and the central axis. The distal portion includes a core member extending between the intermediate portion and the distal end, and stabilization elements embedded in the core member adjacent the accessory lumen and defining a stabilization plane that intersects the steering plane at a location offset from the central region, e.g., closer to the accessory lumen than the steering element lumen.
    • 提供了用于在患者体内执行包括管状构件的装置,所述管状构件包括近端和远端,在其间延伸的中心轴线或区域以及从中间部分向远端向远侧延伸的远侧部分。 一个或多个附件腔和转向元件腔在近端和远端之间延伸,所述转向元件腔从所述远侧部分内的中心区域偏移,使得转向平面与所述转向元件腔和所述中心轴相交。 所述远侧部分包括在所述中间部分和所述远端之间延伸的芯部件,以及稳定元件,所述稳定元件嵌入在所述芯部件中,邻近所述辅助内腔并且限定在偏离所述中心区域的位置处与所述转向平面相交的稳定平面, 比辅助腔更靠近辅助腔。
