Abstract: Medical leads include a lumen body at an end of the lead, and the lumen body includes multiple filar lumens. The lumen body is joined to a lead body, and electrical connectors are longitudinally spaced along the lumen body. Filars within the filar lumens are directed through filar passageways within the lumen body to attach to the electrical connectors on the lumen body. The filar passageways may be aligned with the filar lumens, and slots within the electrical connectors may be aligned with the filar passageways to facilitate assembly. The lumen body may provide additional stiffness to the end of the lead where the lumen body is located to facilitate lead insertion into the medical device. The filar lumens of the lumen body may have a longitudinally straight configuration so that the portions of filars within the filar lumens are held in a longitudinally straight configuration.

Abstract translation: 医疗引线包括在引线端部的管腔体，并且内腔体包括多个丝腔。 管腔体连接到引线体，并且电连接器沿着管腔体纵向间隔开。 丝腔内的丝状体通过管腔体内的丝状通道引导以附着到管腔体上的电连接器。 丝状通道可以与丝状腔一致，并且电连接器内的槽可以与丝状通道对准以便于组装。 腔体可以在管腔主体所在的引线的端部提供额外的刚度，以便于将引线插入到医疗装置中。 管腔体的丝状腔可以具有纵向直线构造，使得丝状腔内的丝状体的部分保持在纵向直线构造中。
