1. A system for treating a condition in a body lumen, comprising:
a first catheter having a first retaining member and a second catheter having a second retaining member, wherein the first and second retaining members are configured for positioning within the body lumen and wherein a position of the first and second retaining members are adjustable relative to one another so as to define a treatment area between the retaining members;
a cryoablative agent in fluid communication with the treatment area;
a pressure sensing element located on the first or second catheter;
a controller in communication with the pressure sensing element and the first and second retaining members,
wherein the controller is configured to compare a first pressure within the treatment area from the pressure sensing element against a second pressure within the first or second retaining member, and
wherein the controller is further configured to adjust the first pressure to be below the second pressure such that the first pressure is maintained below the second pressure over a predetermined treatment time.
