Abstract
A method of preparing a cryo-surgical system for treatment includes accessing a container containing a refrigerant, a delivery tube having a first end configured to be in flow communication with the container and a second end opposite the first end. The system further includes a plurality of flexible finger portions disposed proximate the second end of the delivery tube opposite the first end. A porous applicator bud is disposed proximate the second end of the delivery tube. The porous applicator bud includes a body portion disposed between the plurality of flexible finger portions and a contact surface extending from the plurality of flexible finger portions. An adjustment ring disposed along the delivery tube adjacent to the plurality of flexible finger portions can be used to adjust the size of the contact surface of the porous applicator bud.
