Abstract
Abstract A cryogenic catheter having an elongate outer member and a plurality of inner members disposed within the elongate outer member is provided. The inner members define at least one cryogenic path through the outer member. At least one of the inner members has at least one controllable opening formed thereon to selectively release cryogenic fluid. The inner members also include an overtube and an injection tube slideably disposed to one another.
