Abstract
A lead has a flexible lead body which extends from a proximal end to a distal end. The lead body has a conductor coupled with an electrode. At least a portion of the conductor includes a layer of echogenic material encapsulated by the lead body. Alternatively, the echogenic material includes a coating of material. Optionally, the layer of echogenic material is disposed on at least a portion of the conductor or on one or more portions of the conductor.
Claims20
A method for forming a lead assembly:
- providing a lead body with an outer surface, the lead body having a proximal end and a distal end;
- associating a conductor with the lead body;
- electrically coupling at least one electrode with the conductor;
- and
- disposing electrogenic material at two or more different locations on the conductor.
2 more elements
A lead assembly comprising:
- a flexible lead body extending from a proximal end to a distal end, the lead body including at least one conductor disposed therein, the flexible lead body including an outer surface;
- an electrode assembly including at least one electrode electrically coupled with the conductor;
- and
- means for rendering at least a portion of the conductor echogenic in two or more different locations, where the echogenic portion of the conductor is at least partially encapsulated by the flexible lead body.
