A redundant temperature monitoring system and method for an electrosurgical system are provided. The temperature monitoring circuit includes at least one temperature sensor for sensing a temperature at a measuring point, a first temperature measurement circuit coupled to the at least one temperature sensor for generating a first temperature value, a second temperature measurement circuit coupled to the at least one temperature sensor for generating a second temperature value, and a control circuit for determining a difference between the first and second temperature values and for comparing the difference to a first predetermined threshold. If the difference is greater than the first predetermined threshold, the control circuit generates a warning signal. If the difference is greater than a second predetermined threshold, the control circuit generates an alarm signal and / or shuts down a power source of the electrosurgical system.

The present invention is a wireless power system which includes components which can be recharged by harvesting wireless power, wireless power transmitters for transmitting the power, and devices which are powered from the components. Features such as temperature monitoring, tiered network protocols including both data and power communication, and power management strategies related to both charging and non-charging operations, are used to improve performance of the wireless network. Rechargeable batteries which are configured to be recharged using wireless power have unique components specifically tailored for recharging operations rather than for providing power to a device. A wireless power supply for powering implanted devices benefits from an external patient controller which contains features for adjusting both power transmission and harvesting provided by other components of the wireless power network.

Indication of worsening health condition in patients with congestive heart failure using the analysis of the speed and pattern of temperature change in a way that is individualized toward patient's health condition.

An ultrasonic system useful for providing imaging, therapy and temperature monitoring generally comprises an acoustic transducer assembly configured to enable the ultrasound system to perform the imaging, therapy and temperature monitoring functions. The acoustic transducer assembly comprises a single transducer that is operatively connected to an imaging subsystem, a therapy subsystem and a temperature monitoring subsystem. The ultrasound system may also include a display for imaging and temperature monitoring functions. An exemplary single transducer is configured such that when connected to the subsystems, the imaging subsystem can generate an image of a treatment region on the display, the therapy subsystem can generate high power acoustic energy to heat the treatment region, and the temperature monitoring subsystem can map and monitor the temperature of the treatment region and display the temperature on the display, all through the use of the single transducer. Additionally, the acoustic transducer assembly can be configured to provide three-dimensional imaging, temperature monitoring or therapeutic heating through the use of adaptive algorithms and / or rotational or translational movement. Moreover, a plurality of the exemplary single transducers can be provided to facilitate enhanced treatment capabilities.
