Abstract
A system for cryoablating target tissue at a treatment site includes a cryo-element that is attached to the distal end of a cryo-catheter. An annular shaped balloon is attached to a cylindrical shaped sleeve and the sleeve is slideably mounted over the cryo-catheter. The distal end of a fill tube is attached to the sleeve to place the lumen of the fill tube in fluid communication with the balloon. In use, the cryo-element is first positioned at the treatment site using the cryo-catheter. Next, the fill tube is used to advance the balloon and sleeve over the cryo-catheter until the balloon is interposed between the cryo-element and the target tissue. Saline solution is then pumped through the fill tube to expand the balloon between the cryo-element and target tissue. A refrigerant is then expanded in the cryo-element which freezes the saline solution and cryoablates the target tissue.
