Implantable medical lead including tine markers
First Claim
1. An implantable medical lead comprising:
- a lead body extending between a proximal end and a distal end;
an electrode disposed proximate to the distal end of the lead body;
a plurality of tine elements extending from the lead body;
a first marker positioned on the lead body between the proximal end and all of the tine elements extending from the lead body; and
a second marker separate from the first marker and positioned on the lead body between the distal end and all of the tine elements extending from the lead body.

Abstract
An implantable medical electrical lead particularly for stimulation of the sacral nerves comprises a lead body extending between a distal end and a proximal end, and the distal end having at least one electrode of an electrode array extending longitudinally from the distal end toward the proximal end. The lead body at its proximal end may be coupled to a pulse generator, additional intermediate wiring, or other stimulation device. A fixation mechanism is formed on or integrally with the lead body proximal to the electrode array that is adapted to be implanted in and engage subcutaneous tissue, particularly muscle tissue, to inhibit axial movement of the lead body and dislodgement of the stimulation electrodes.

18. A method of implanting a medical lead proximate to a stimulation site in a patient, the method comprising:
-
introducing an introducer into body tissue, the introducer comprising a lumen extending between a lumen proximal end and a lumen distal end; advancing the medical lead through the lumen of the introducer, the medical lead comprising; a lead body extending between a proximal end and a distal end; an electrode disposed proximate to the distal end of the lead body; a plurality of tine elements extending from the lead body; a first marker positioned on the lead body between the proximal end and all of the tine elements extending from the lead body; and a second marker separate from the first marker and positioned on the lead body between the distal end and all of the tine elements extending from the lead body; positioning the lumen distal end of the lumen proximate to the stimulation site to dispose the electrode in operative relation to body tissue to be stimulated; and withdrawing the introducer proximally past the first marker on the lead body to release the plurality of tine elements. - View Dependent Claims (19, 20, 21, 22)
