Abstract
A medical electrical lead includes a canted lead body distal portion extending from an approximately straight lead body proximal portion; the canted distal portion includes an approximately straight segment and a hump-like segment extending from a first end, in proximity to the approximately straight segment, to a second end. The lead further includes a first electrode coupled to the approximately straight segment of the distal portion and a second electrode coupled to the distal portion in proximity to a second end of the hump-like segment.
Claims21
A medical electrical lead, comprising:
- an approximately straight proximal lead body portion;
- a distal lead body portion extending from the proximal portion and comprising:
- a first arcuate segment bending in a first direction,
- an approximately straight segment extending from the first arcuate segment,
- a second arcuate segment extending from the approximately straight segment and bending in a second generally distal direction,
- a third arcuate segment extending from the second arcuate segment and bending in a third generally proximal direction, which is also generally opposite the second direction, and
- a distal tip segment extending from the third arcuate segment;
- a first electrode coupled to the approximately straight segment of the lead body distal portion;
- and
- a second electrode coupled to the distal tip segment of the lead body distal portion.
