Abstract
An implantable electrical stimulation lead includes a tip electrode disposed on a distal tip of the lead body. One tip electrode has a base and a separate plug attached to the base. The base defines an interior lumen closed at one end by the plug. Another tip electrode has an electrode body, a stem extending from the electrode body, and shaped retention features extending from the stem. Yet another tip electrode has an electrode body, a stem extending from the electrode body, and a flange disposed on the stem opposite the electrode body. A further tip electrode has an electrode body defining an interior lumen and a plurality of protrusions extending into the interior lumen. Another tip electrode has an electrode body and arms extending from the electrode body. The electrode body defines an interior lumen and the arms extend over an opening to the interior lumen.
