Abstract
A system and method for creating radial-linear lesions in tissue. The system includes a cryoablation device having a first balloon, a second balloon disposed about the first balloon, and one or more splines disposed between the first balloon and second balloon, each spline defining a plurality of ports. The splines may be in communication with a coolant supply, and the first balloon may be in communication with a coolant supply or non-coolant inflation fluid supply. When the first balloon is in the uninflated configuration, the splines may have a substantially linear configuration. Each of the splines may be radially oriented about an elongate shaft and transitionable between the substantially linear configuration and an arcuate configuration when the first balloon is in the inflated configuration. Coolant expelled from the splines between the first and second balloons creates an ablation pattern on the outer surface of the second balloon.
