    摘要： A system for treating tissue in a patient includes a body having a cooling fluid supply path and a tissue piercing probe in fluid communication with the cooling fluid supply path. The probe extends distally from the body and is insertable into the tissue through the patient's skin. A cooling fluid source is fluidly coupled with the probe such that when cooling is initiated, cooling fluid flows in the probe thereby cooling the probe and any adjacent tissue. A heater element is in thermal engagement with the cooling fluid source and a power source provides power to the heater element thereby heating the cooling fluid. The power source has sufficient power to heat the cooling fluid to at least a desired temperature but has insufficient power to heat the cooling fluid above a critical temperature which results in rupture of the cooling fluid source.

    摘要： A redundant temperature measurement probe is described that may include any number of features. In one embodiment, the probe includes a pair of resistive sensors, a pair of output wires, and a shared ground wire for a total of three wires. The first and second resistive sensors of the probe can be electrically connected to a controller to measure temperature and detect when a fault in the probe occurs. In some embodiments, the controller can be configured to detect a shift in resistance

    摘要： A systems and methods for controlling temperature in a cryogenic device includes providing a device having a probe and a heater element. A distal region of the probe is engaged with the target region. Measuring and recording current temperature of a proximal region of the probe and time of the measurement is used to determine slope of a temperature curve defined by two points. The first point is defined by the current temperature and time of measurement and a second point is defined by a previous measurement of proximal region temperature and time of measurement. When the slope is less than a slope threshold value a treatment flag is activated, treatment start time is recorded and the proximal region is heated with the heater element. Heating is discontinued and the treatment flag is deactivated after elapsed treatment time exceeds a duration threshold value.

    摘要： Devices, systems, and methods efficiently dilate and/or cool blood vessels and other body tissues. Controlled cooling with balloon catheters and other probes may be effected by a change in phase of a cryogenic fluid, often after measuring a minimum pulse width for actuating an individual solenoid valve along the cooling fluid path, with the measured pulse width allowing gradual inflation of a balloon without excessive venting of cooling fluid.
