Abstract
The present disclosure relates generally to the field of cryotherapy. In particular, the present disclosure relates to cryotherapy systems that ensure egress of cryogen gas delivered within a patient's body during cryotherapy procedures and, more particularly, sensors for use with cryotherapy systems that include delivery catheters wherein the systems ensure that egress of cryogen gas from the patient's body is possible whenever the catheter is operating.
