CRYO-SURGICAL SYSTEMS AND METHODS OF USING THE SAME

摘要

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.

主权项

1. A method of preparing a cryo-surgical system, the method comprising:
accessing a container containing a refrigerant and a delivery tube having a first end configured to be in flow communication with the container and a second end opposite the first end and including a plurality of flexible finger portions disposed proximate the second end of the delivery tube opposite the first end; providing a porous applicator bud disposed proximate the second end of the delivery tube, the porous applicator bud having a body portion disposed between the plurality of flexible finger portions and a contact surface extending from the plurality of flexible finger portions; and adjusting a size of the porous applicator bud by at least partially removing compression forces from the porous applicator bud to increase the size of a contact surface of the porous applicator bud or engaging the plurality of flexible finger portions and thereby compressing the contact surface of the porous applicator bud.
