Abstract:
1. A method of manufacturing an implantable electrical lead body that is MRI compatible for the purpose of diagnostic quality imaging, comprising the steps of: a. providing a mandrel defining a first end, a second end and an outer diameter; b. applying a first substrate layer over the mandrel; c. reflowing the first substrate layer to conform closely to the mandrel; d. winding at least one conductive coil layer around the outer surface of the first substrate layer, wherein the conductive coil layer as a helix pitch and diameter; e. securing the conductive coil layer to the mandrel at least at the first end and the second end; f. applying a second substrate layer over the first substrate layer and the conductive coil layer; g. reflowing the second substrate layer to fuse with the first substrate layer and encapsulate the conductive coil layer, permanently securing the conductive coil layer to the lead body and preserving the helix pitch and diameter; h. applying a third substrate layer over the second substrate layer; i. reflowing the third substrate layer to fuse with the second substrate layer; j. removing the lead body from the mandrel; and k. trimming the lead body to expose the conductive coil layer, allowing the lead body to be capable of electrical communication.
