Systems and methods for making tip electrodes for leads of electrical stimulation systems

摘要

An implantable electrical stimulation lead includes a lead body, electrodes disposed along a distal end of the lead body, terminals disposed along the proximal end of the lead body, and conductors coupling the terminals to the electrodes. The electrodes include a tip electrode having an electrode body with an outer stimulating surface. An internal lumen is defined in the electrode body and extends inwardly from an opening in a proximal end of the electrode body. Side apertures are formed between the outer stimulating surface and the internal lumen. A portion of the lead body is disposed within the internal lumen and side apertures through the opening in the proximal end of the electrode body. Thai portion of the lead body facilitates retention of the tip electrode on a distal tip of the lead body.
