A medical electrical lead having a multi- ple conductors located within an elongated lead body (10) which is provided with multiple con- ductor lumens (100, 102, 104) each containing a conductor (112, 114) and with at least one compression lumen (106, 108, 110) which does not contain a conductor. The conductor lumens (100, 102, 104) are spaced from one another by a first, minimum spacing and the compression lumen (106, 108, 110) or lumens are located in- termediate the conductor lumens and are spaced from the conductor lumens by a second, min- imal spacing of less than said first minimum spacing. The centers of the compression lu- mens (106, 108, 110) are located along lines which pass through both the center of a con- ductor lumen and the center of the lead body. The arrangement of the conductor and compres- sion lumens enhances the lead's ability to sur- vive crushing forces such as applied by the first rib and clavicle.
Dérivation électrique médicale possédant des conducteurs multiples situés à l'intérieur d'un corps allongé (10) pourvu de lumières multiples (100, 102, 104) contenant chacune un conducteur (112, 114), ainsi que d'au moins une lumière de compression (106, 108, 110) qui ne contient pas de conducteur. Les lumières (100, 102, 104) sont éloignées les unes des autres selon un premier espacement minimum et la lumière ou les lumières de compression (106, 108, 110) sont situées en position intermédiaire par rapport aux lumières contenant les conducteurs et éloignées de ces dernières selon un deuxième espacement minimum inférieur audit premier espacement minimum. Les centres des lumières de compression (106, 108, 110) sont situés le long de lignes traversant à la fois le centre d'une lumière de conducteur et le centre du corps de dérivation. La disposition des lumières de conducteur et de compression améliore la capacité de la dérivation à résister à des forces d'écrasement, telles que celles qui sont exercées par la première côte et la clavicule.
