  • Patent number: 11918754
    Abstract: A ureteral catheter for placement in a kidney, renal pelvis, and/or in a ureter adjacent to the renal pelvis of a patient, includes: an elongated tube having a proximal end, a distal end, and a sidewall extending therebetween defining at least one drainage lumen extending through the tube, wherein a proximal portion of the elongated tube is essentially free of or free of openings; and an expandable retention portion which defines a three-dimensional shape positioned to maintain fluid flow from the kidney through at least the distal end of the tube and inhibit tissue of the ureter or renal pelvis from occluding the at least one drainage lumen at the distal end of the elongated tube upon application of negative pressure through the drainage lumen, wherein the three-dimensional space defined by the expandable retention portion encloses at least a portion of the distal end of the elongated tube.

  • Patent number: 4201427
    Abstract: A mechanism for positioning a sewing machine in a sewing machine cabinet includes an improved linkage attached to the cabinet and supporting a mounting platform for the sewing machine. The linkage permits movement of the platform between a storage position within the cabinet to either one of two horizontal operating positions. The linkage includes one pair of pivot arms connected from each side of the platform to a bracket suspended from the cabinet. Also one support pin projects from each side of the platform and cooperatively engages an associated positioner attached to the cabinet. The positioners retain the platform in either horizontal operating position. The platform may be tilted from the horizontal operating positions to release the support pins from the positioners and permit movement of the platform to another desired position.

  • Patent number: 4018487
    Abstract: An improved sewing machine head lifter mechanism for supporting a sewing machine head in a cabinet includes a support linkage with a spring support mechanism for the linkage. An adjustable cam member is provided for cooperation with the spring mechanism. Thus, the adjustable cam engages one end of a tension spring. The opposite end of the spring engages a head support bracket. The spring is supported intermediate its ends. Pivotal movement of the cam member adjusts tension of the spring to provide the requisite force for supporting the head support bracket and an attached sewing machine head.

  • Patent number: 3936084
    Abstract: A plastic privacy lock for recreation vehicles and the like includes an outside handle portion for the outside of a door and an inside portion for the inside of a door. The outside portion includes an outside handle having a rotatable outside latch lever to operate a bolt on the inside portion. The inside portion includes a handle and a housing with the bolt in the housing. The bolt and an inside bolt actuator are formed as a single integral molded plastic part positioned within the housing. To move the bolt out of engagement with a strike from the inside, manual operation of the molded plastic bolt against the force of a biasing spring is required. A locking bar or dog having a locked and unlocked detent position is also provided in the housing. The locking bar is accessible from the inside portion of the lock. In locked position, the locking bar holds a bolt shifter connected to the outside latch lever to prevent rotation and operation of the lock.
