  • Patent number: 11701488
    Abstract: Disclosed is a catheter device including a proximal tube having a first part of a first lumen; a distal tube having a second part of the first lumen; a second lumen connecting the proximal tube and the distal tube; wherein the connection comprise an area of discontinuity between the first part and second part; wherein the area of discontinuity comprises a support element configured to resist axial movement of the distal tube relative to the proximal tube and vice versa; and wherein the second lumen is arranged to activate or cause at least one obstruction element to restrict the flow of urine from the proximal tube to the area of discontinuity and to restrict the flow of urine from the area of discontinuity to the distal tube.
