Implantable medical leads having oscillating cable conductor lumens

摘要

An electrical implantable lead includes an elongated lead body having a plurality of lumens therein, including at least one linear lumen and at least one planar, non-linear lumen and a plurality of conductor cables disposed within the plurality of lumens. The electrical implantable lead further includes a terminal connector coupled to a proximal end of the lead body, the terminal connector being in electrical communication with at least one of the plurality of conductor cables. Further, the electrical implantable lead includes at least one electrode coupled to the lead body, the at least one electrode in electrical communication with at least one of the plurality of conductor cables. In accordance with various embodiments, the at least one non-linear lumen extends longitudinally along a portion of the lead body and includes a plurality or crests and a plurality of troughs.

主权项

1. A method of manufacturing an implantable medical lead, the method comprising:
extruding a polymeric material through a die configured to create a plurality of lumens within the implantable medical lead, wherein the plurality of lumens extend along a longitudinal axis of the die; twisting the die with respect to the longitudinal axis alternatively in a clockwise direction and a counterclockwise direction while extruding such that twisting in the clockwise direction creates a trough and in the counterclockwise direction creates a crest in the plurality of lumens; and inserting a conductor cable in each of the plurality of lumens.
