Patent number: 11759601Abstract: A urodynamic investigation apparatus for receipt of urine from a bladder is provided. The apparatus is characterized by a tubular element, first and second fittings, and a sleeve element, for select passage of urine there through, within the tubular element. The tubular element is characterized by opposing first and second end portions, and a port. The fittings are adapted to be received by the opposing end portions of the tubular element so as to delimit an apparatus chamber. The sleeve element, suspended between the fittings within the chamber, has collapsed and open configurations. The collapsed configuration is indicative of a no urine flow condition, and the open configuration indicative of a urine flow condition, with the sleeve element urine flow condition being a function of pressure applied to the chamber via the port of the tubular element.Type: GrantFiled: April 30, 2021Date of Patent: September 19, 2023Assignee: SRS Medical Systems, LLCInventor: Lee Brody

Patent number: 11752302Abstract: An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that extends over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. A bladder plug configured on the distal end of the inner catheter may form a seal between the catheter sheath and the inner catheter. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.Type: GrantFiled: November 28, 2022Date of Patent: September 12, 2023Inventor: Stanislaw Zukowski
