Abstract

See full text

A cryotherapy catheter can include an elongate member and an inflatable balloon at a distal end of the elongate member, the elongate member having lumens formed therein to supply cryogenic fluid to a chamber of the balloon and to channel exhaust from the balloon chamber; and a controller programmed to control a first rate at which the cryogenic fluid is supplied to the balloon chamber and a second rate at which exhaust is channeled from the balloon chamber, wherein the controller is programmed to a) develop, during a first phase of a cryotherapy procedure, a first pressure inside the balloon chamber at a value that is greater than an ambient pressure outside and adjacent to a proximal end of the elongate member, and b) develop, during a second phase of the cryotherapy procedure, the first pressure at a value that is less than the ambient pressure.
