  • Publication number: 20240350198
    Abstract: Kidney stone removal system is disclosed having components including a handle mechanism, a nozzle tip, and a guiding device. The handle mechanism employs a trigger that enables control of irrigation and vacuum/suction. Depression of a trigger in the trigger mechanism conveys status of vacuum/suction and irrigation to a user by providing increased resistance at different points of depression. When the trigger is in a home (undepressed) position, irrigation and vacuum/suction are turned off. When the trigger is in a fully depressed position, irrigation and vacuum/suction are turned on. When the trigger is in an intermediate position, irrigation may be turned on, while vacuum/suction remains turned off. The nozzle includes one or more irrigation ports positioned at a distal end of the nozzle and having an irrigation port departure angle of 30 to 60 degrees for directing irrigation fluid forward and laterally from the distal end of the nozzle.

  • Publication number: 20230006809
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that perform homomorphic computations on encrypted third-party data within a distributed computing environment. For example, an apparatus receives a homomorphic public key and encrypted transaction data characterizing an exchange of data from a computing system, and encrypts modelling data associated with a first predictive model using the homomorphic public key. The apparatus may perform homomorphic computations that apply the first predictive model to the encrypted transaction data in accordance with the encrypted first modelling data, and transmit an encrypted first output of the homomorphic computations to the computing system, which may decrypt the encrypted first output using a homomorphic private key and generate decrypted output data indicative of a predicted likelihood that the data exchange represents fraudulent activity.
