A focused treatment tip (FTT) for controlling the evaporation rate and providing targeted delivery of low temperature liquified gases for contact with living tissue includes a contoured body. When filled with liquified gas, the device insulates the gas from waste heat sources, such as the surrounding environment. The device can control the evaporation rate of the liquified gas at the treatment site. The controlled evaporation rate affects the rate of heat transfer from the treated tissue allowing for controlled exposure times and desired outcomes. The device can be used with various application tips to further define the target tissue area to be treated while minimizing collateral damage to surrounding tissue and isolating the gas within the contoured body and focusing heat transfer to the desired treatment area. The device may use transparent materials that make the treatment visible to the operator while the liquified gas is evaporating.

Focused treatment tip design and method to optimize heat transfer through low temperature fluids and gases

The portable cryosurgical device is economical, easy to use and operate, and delivers cryogenic material such as nitrous oxide and carbon dioxide gas in any direction or orientation. The delivered materials destroy target tissue using extremely cold temperatures and the abrasives formed when the cryogenic material becomes a solid. The device includes a portable countertop enclosure housing a cryogen source, a cryogen flow tube in fluid communication with the cryogen source, and a flow path assembly. The flow path assembly includes a valve between the cryogen source and the cryogen flow tube having substantially zero dead volume. The flow path assembly can include a quick-connect cryogen tank adapter and an in-line cryogen filter. The flow path assembly delivers liquefied compressed gas from the cryogen source to a terminal end of the cryogen flow tube without a phase change occurring in the flow path.

A flow modulation devicefor controlling a rheological state of a dispensed pressurized fluid includes a porous elementand an exit tube. The porous elementis in fluid communication with a distal end of an outlet tubeand receives pressurized fluid in a first rheological state. The porous elementincludes a plurality of channels that divide a flow channel into a plurality of flow paths through which the pressurized fluid flows and that modulates the flow of the pressurized fluid. The exit tubeincludes proximal endand distal endand an intermediate body including a sidewalldefining a hollow internal lumenThe exit tubeis in fluid communication with the porous elementand receives the modulated pressurized fluid from the plurality of flow paths and refocuses the fluid to dispense the pressurized fluid in a second rheological state.

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.

A cryo-surgical system may comprise 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 may further include a plurality of flexible finger portions disposed proximate a second end of the delivery tube opposite the first end, an applicator bud having a body portion disposed within the plurality of flexible finger portions and a contact surface extending from the plurality of flexible finger portions. An adjustment ring may be disposed along the delivery tube adjacent to the plurality of flexible finger portions. The contact surface of the bud may be changeable by adjustment of the adjustment ring.

A cryosurgery device for dispensing a liquid refrigerant from a container having a valve stem extending outwardly therefrom. The device includes an actuator adapted to seat on the valve stem of the container in order to depress the valve stem to release the refrigerant from the container. The actuator includes an inner passageway having opposed ends disposed therein, one of the ends of the passageway being in fluid communication with the valve stem. An applicator tube is mounted to the actuator at the other end of the inner passageway. A cap is disposed on the top of the container. The actuator is movably positioned on the cap and a shield is attached to the cap to completely receiving the applicator tube. Liquid refrigerant can only be dispensed when the actuator is positioned properly and the applicator tube is disposed within the shield means.
