Abstract
An ablation device, comprises a first tubular element and a first electrode which, when in an insertion configuration, is received within the first tubular element, the first electrode being deployable from the first tubular element to anchor in a target portion of tissue at a first electrode operative position in combination with a second electrode which, when in the insertion configuration, is received within the first tubular element, the second electrode being deployable from the first tubular element to anchor in the target portion of tissue at a second electrode operative position separated from the first electrode operative position, the second electrode being deployable independently of the first electrode and an insulating element movable relative to the first electrode to insulate selected portions of the first electrode. The device is employed to ablate first and second portions of tissue.
