Abstract: Systems and devices for cooling and dispensing a beverage fluid are disclosed herein. One beverage dispensing system includes a beverage tower comprising a tower body, a shank, and a faucet. In some implementations, a coolant line is routed proximal to a beverage supply line through the tower body, through the shank, and into the faucet. In these and other implementations, the faucet includes a removable nozzle having a supplemental portion of the coolant line. In these and still other implementations, the faucet include a removable nozzle having a second coolant line. The coolant line and the second coolant line are configured to transport a coolant medium proximal to a beverage fluid in the beverage supply line to maintain or adjust the temperature of the beverage fluid. Many other features are described herein.

Abstract: Provided herein are systems, devices, and methods for performing a medical procedure on a patient. The system comprises an ablation catheter comprising a shaft, at least one therapeutic element positioned on the shaft, and one or more tissue-contact sensing components configured to provide a contact signal related to the level of contact between the at least one therapeutic element and tissue. The system further comprises: an energy delivery unit configured to deliver ablative energy to the at least one therapeutic element to create a lesion in target tissue, and to provide an energy delivery data; a force module configured to receive the contact signal and provide contact data; and a processing unit configured to determine an ablation index based on both the energy delivery data and the contact data. The ablation index can represent the status of the lesion being created.
