Abstract
A lead, method of manufacturing same, and system for stimulation is provided. The lead includes an insulative member or layer that masks a portion of the electrode(s) to effectively generate a directional lead that focuses or directs the stimulation to desired location(s). In another embodiment, the lead further includes a marking system to allow a clinician to orient the directional lead, as desired, while the lead is within a body.
Claims9
A stimulation lead for applying electrical pulses to tissue of a patient, comprising:
- an elongated lead body having a distal end and a proximate end;
- at least one conductor within the lead body;
- at least one electrode at the distal end of the lead body, the at least one electrode circumscribing the lead body;
- an insulative member disposed over the at least one electrode, the insulative member having an opening such that the opening exposes a limited angular range of the at least one electrode;
- and
- a marking structure for determining an angular orientation of the lead body, the marking structure disposed to at least partially circumscribe the lead body, wherein the marking structure comprises a radio-opaque portion such that an edge of the marking structure between the radio-opaque portion and a non-radio-opaque portion is substantially aligned with a mid-line of the exposed angular range of the at least one electrode.
