Patent 6926711 was granted and assigned to Cryocor on August, 2005 by the United States Patent and Trademark Office.
A catheter usable for cryogenic ablation of tissues is described. The catheter has a deflectable segment with a reduced diameter and a tip portion with a diameter greater than the reduced diameter. A resilient element allows for bending of the deflectable segment preferentially in one plane, and an actuator is used to control the bending of the deflectable segment.
