Abstract
Disclosed herein are devices, systems, and method for multi-stage, reusable coupling. Such a coupler can have a formable flow path and can include a first sealing engagement and a second sealing engagement. The first sealing engagement can be configured to provide a first seal of the coupler at a first temperature condition. The second sealing engagement can be configured to provide a second seal of the coupler at a second temperature condition that is different from the first temperature condition.
Claims20
A coupler with a formable flow path, the coupler comprising:
- a first sealing engagement that is configured to provide a first seal of the coupler at a first temperature condition and
- a second sealing engagement that is configured to provide a second seal of the coupler at a second temperature condition that is different from the first temperature condition.
A cryosurgery system comprising a cryosurgical tool having a cryogenic media supply conduit and a source of cryogenic media having a cryogenic media feed conduit connectable to the cryogenic media supply conduit via a coupler comprising:
- a first sealing engagement that is configured to provide a first seal of the coupler at a first temperature condition and
- a second sealing engagement that is configured to provide a second seal of the coupler at a second temperature condition that is different from the first temperature condition.
A method of coupling a source of cryogenic fluid to a cryosurgical tool using a coupler, the method comprising;
- sealing the coupler with a first seal via a first sealing engagement that is configured to provide the first seal of the coupler at a first temperature condition and
- sealing the coupler with a second seal via a second sealing engagement that is configured to provide the second seal of the coupler at a second temperature condition that is different from the first temperature condition.
