Abstract
A cryogen delivery system includes a probe configured to deliver a cryogenic fluid to a treatment location, a cryogen inlet configured to interface with a cryogenic fluid supply vessel to transfer cryogenic fluid from the cryogenic fluid supply vessel to the probe, a support structure configured to position the cryogenic fluid supply vessel relative to the cryogen inlet, and a sensor coupled to the support structure. The sensor is configured to generate a signal indicative of a weight of a cryogenic fluid contained in the cryogenic fluid supply vessel. Devices and methods relate to cryogen delivery systems.
Claims22
A cryogen delivery system, comprising:
- a probe configured to deliver a cryogenic fluid to a treatment location;
- a cryogen inlet configured to interface with a cryogenic fluid supply vessel to transfer cryogenic fluid from the cryogenic fluid supply vessel to the probe;
- a support structure configured to position the cryogenic fluid supply vessel relative to the cryogen inlet;
- and
- a sensor coupled to the support structure and configured to generate a signal indicative of a weight of a cryogenic fluid contained in the cryogenic fluid supply vessel.
A method for determining an amount of cryogenic fluid in a cryogenic fluid supply vessel, the method comprising:
- generating a signal from a sensor coupled to a support structure on which a cryogenic fluid supply vessel is located, the signal being indicative of a total weight of the cryogenic fluid supply vessel;
- and
- determining an amount of cryogenic fluid present in the cryogenic fluid supply vessel based on the signal.
