Abstract

A medical electrical lead includes a canted lead body distal portion extending from an approximately straight lead body proximal portion and including 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. A first electrode is 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. A medical electrode includes an active surface extending from a first end to a second end and has a maximum outer diameter exceeding an outer diameter of the both the first end and the second end. The electrode further includes a recess formed in the active surface and an agent held in the recess and adapted to disperse out from the recess upon implantation of the electrode.
