1. An ablation catheter comprising:
an inner tube comprising a length, a distal end having a distal tip, and a longitudinal axis; a plurality of needles extending from the distal tip of the inner tube and biased away from the longitudinal axis; an outer sheath slideably moveable relative to the inner tube to surround at least a portion of the length of the inner tube and its extending needles; and a radio frequency energy source electrically connected to the plurality of needles, wherein at least one of the needles comprises a distal portion, a proximal portion, and a hinge between the distal and proximal portions, and wherein the distal portion of the needle is biased outwardly relative to the proximal portion of the needle and the longitudinal axis. |
