Abstract:
1. A method for assembling a transition zone between a medical electrical lead body and a lead connector assembly, the method comprising the steps of: forming a multi-lumen tube having a peripheral lumen extending from a first end to a second end of the tube in a helical path about a central lumen of the tube; positioning the multi-lumen tube adjacent the connector assembly; and positioning a medical electrical lead conductor within the peripheral lumen by inserting an end of the medical electrical lead conductor into the first end of the peripheral lumen and advancing the end of the medical electrical lead conductor through the peripheral lumen; wherein the multi-lumen tube is formed of a polyurethane material and the step of forming the multi-lumen tube comprises: molding or extruding the tube such that the peripheral lumen extends from the first end to the second end approximately aligned with a central axis of the central lumen; twisting the first end of the tube with respect to the second end of the tube such that the peripheral lumen extends in the helical path; securing the first end and the second end in the twisted configuration; and heating the multi-lumen tube while the multi-lumen tube is in the twisted configuration.
