Abstract:
1. An ablation device comprising: a catheter shaft having proximal and distal ends, a distal port, and a passageway extending therethrough; and an elongated probe having proximal and distal sections and one or more ablation elements, wherein said probe is removably received in said passageway, said distal section having an unconstrained shape including a main portion, a hoop region, and a limb portion coupling the main portion to the hoop region, wherein the limb portion extends radially away from the main portion and extends proximally from a distal end of the main portion, said hoop region having said one or more ablation elements thereon, wherein the distal section in the unconstrained shape includes an opening in the hoop region, and the hoop region has a curvature in the distal direction and a distal end of the distal section is angled such that it lies closer to the distal end of the main portion than a juncture between the hoop region and the limb portion.
