Thermal ablation system

摘要

A thermal ablation system comprises a fluid handling unit receiving fluid from a fluid source at a first pressure, the fluid handling unit including a heater heating the fluid to a desired temperature and a pump and an introducer including a sheath which, when in an operative position, is received within a hollow organ, the sheath including a delivery lumen introducing fluid heated by the heater to the hollow organ and a return lumen withdrawing fluid from the hollow organ and returning the withdrawn fluid to the console via a return lumen, wherein the pump increases a pressure of the fluid between the fluid source and the delivery lumen of the introducer.

1. A thermal ablation system, comprising:
a fluid handling unit receiving fluid from a fluid source at a first pressure; an introducer including a sheath which, when in an operative position, is received within a hollow organ, the sheath including a delivery lumen and a return lumen; a heater heating the fluid from the fluid source, the heated fluid being introduced into the hollow organ via the delivery lumen and being returned from the hollow organ to the fluid handling unit via the return lumen; a pump; and a processor controlling the heater to heat the fluid to a desired temperature and the pump to increase a pressure of the fluid between the fluid source and the delivery lumen, the processor further configured to perform a safety procedure on at least one of the heater and the pump as a function of ablation data generated by at least one sensor.
