  • Patent number: 12329396
    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: 12156548
    Abstract: A wearable article includes a front and back elastic belts, a crotch region, a waist opening, and leg openings. Each elastic belt is a laminate having an inner sheet, an outer sheet, and an elastic member. Elastic adhesive bonding continuously bonds the elastic member for at least about 10 mm in the direction of stretch adjacent the side edges of the belts. A discrete patterned adhesive bonding is applied to at least one of the inner and outer sheets to intermittently bond the inner and outer sheets. The discrete patterned adhesive bonding extends substantially along the transverse direction between the elastic adhesive bonding, and substantially along the longitudinal direction between the distal and proximal edges of the elastic belts. The same adhesive agent provides the elastic adhesive and discrete patterned adhesive bonding. Heat bonds form side seams, and the remainder of the laminate is free of heat bonds.
