  • Publication number: 20250268615
    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.

  • Patent number: 12256989
    Abstract: A catheter assembly is provided having a working lumen and a guide. The guide is configured to position a fragmentizing device within the working lumen. The guide is configured to prevent or minimize any unintended movement of a distal section of the fragmentizing device within the working lumen when the distal section of the fragmentizing device is positioned at a distal end of the working lumen.

  • Publication number: 20240001075
    Abstract: Kidney stone removal system is disclosed having components including a handle mechanism. The handle mechanism employs a trigger mechanism that enables control of irrigation and vacuum/suction. Operation of a trigger of the trigger mechanism conveys status of vacuum/suction and irrigation to a user by providing increased resistance at different points of operation. When the trigger is in a home position, irrigation and vacuum/suction are turned off. When the trigger is in a fully activated 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 handle mechanism can be of a single trigger design with modes including: an active irrigation mode only (i.e., active irrigation on/vacuum off) and an active irrigation mode in combination with a vacuum mode (i.e., active irrigation on/vacuum on).
