Abstract: Improved devices, systems, and methods for inhibiting hyperplasia in blood vessels provide controlled and safe cryotherapy treatment of a target portion within a body lumen of a patient. Efficacy of endoluminal cryogenic cooling can be enhanced by limiting cooling of target tissue using a thermal barrier disposed between a dual balloon cryotherapy catheter. Containment of both balloons can be monitored by applying a vacuum within a space between the first and second ballons, and by coupling the vacuum space to a fluid shutoff so as to inhibit flow of cryogenic fluid in response to a change in the vacuum space. Controlled cooling of the vessel can be improved by use of a nebulizer in fluid communication with a cryogenic liquid lumen and a gas supply lumen.
