Leads with tip electrode for electrical stimulation systems and methods of making and using
First Claim
1. An implantable electrical stimulation lead, comprising:
- a lead body comprising a distal portion, a distal tip, and a proximal portion; and
a plurality of electrodes disposed along the distal portion of the lead body, the plurality of electrodes comprising a tip electrode disposed on the distal tip of the lead body, the tip electrode having a conductive base and a separate conductive plug attached to the base, wherein the base defines an interior lumen with a portion of the plug inserted into the interior lumen of the base, wherein the plug has a sloped edge and the interior lumen of the base has a corresponding sloped edge.

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.
