Abstract: A system including a controller to determine an in-body time of a medical device in a patient during a medical procedure. The controller to: receive signals from at least one temperature sensor; detect insertion of the medical device into the patient by one or more of determining the temperature of the medical device and determining the change of temperature of the medical device with respect to time; increment an in-body time counter to measure the in-body time of the medical device after detecting insertion of the medical device into the patient; detect that the medical device has been removed from the patient by determining that the change of temperature of the medical device with respect to time is negative; and stop incrementing the in-body time counter in response to detecting that the medical device has been removed.

Abstract: Various aspects of the present disclosure are directed towards apparatuses, systems, and methods for electroporation ablation. The electroporation ablation catheter may include an electrode assembly comprising one or more electrodes configured to generate electric fields in target tissue in response to a plurality of electrical pulse sequences delivered in a plurality of therapy sections, and an ultrasound transducer configured to generate a first set of ultrasound signals during a first electrical pulse sequence of the plurality of electrical pulse sequences and generate a second set of ultrasound signals after an end of the first electrical pulse sequence and before a beginning of a second electrical pulse sequence, the second electrical pulse sequence being an electrical pulse sequence subsequent to the first electrical pulse sequence.

Abstract: A control system for a cryogenic ablation system. The control system including an extracorporeal ultrasound sensor and a controller. The extracorporeal ultrasound sensor is configured to detect blood flow in a vein and generate an output signal indicative of blood flow velocity of the blood flow in the vein, and the controller is configured to receive the output signal and determine whether the vein has been occluded by a cryoablation balloon catheter.

Abstract: A cryotherapy system for use in an operating environment, the cryotherapy system comprising a balloon catheter comprising a balloon defining an internal space, and a fluid control system configured to control delivery of a cryogenic fluid to the balloon catheter so as to maintain the internal space at a desired working pressure. The fluid control system comprises a controller configured to receive an external ambient pressure input and to control or calibrate the delivery of the cryogenic fluid based in part on the external ambient pressure input.
