Abstract
An improved medical electrical lead is disclosed herein. The lead may include a longitudinally extending body having a distal end, a proximal end, a conductive element extending between the distal and proximal ends, and an electrode coupled to the conductive element utilizing a reflow process. The conductive element and electrode may comprise materials that are incompatible.
Claims14
A method for manufacturing an implantable medical electrical lead device, comprising:
- providing a lead sub-assembly comprising an elongate conductor, an electrode and a first insulative layer, wherein the elongate conductor has a first thermal melting point and the electrode has a second thermal melting point that is higher than the first thermal melting point;
- covering at least a portion of the elongate conductor with the first insulative layer to form an elongate device body;
- positioning the electrode at a predetermined location on the elongate conductor;
- and
- coupling the electrode to the elongate conductor, wherein:
- the coupling includes reflowing the material of the elongate conductor onto the electrode and
- the reflowing comprises heating the lead sub-assembly to a temperature that causes the melting of the elongate conductor without melting the electrode.
