1. A detachable catheter apparatus for insertion into a bladder of a living being through a urethra of the living being to convey a fluid, comprising:

  • a tube assembly extending along a longitudinal axis and including a distal tube section having a closed end and an opposite opened end, a proximal tube section having a first end and an opposite second end and a connector fabricated from a flexible, deformable material, the connector connecting the opened end of the distal tube section and the first end of the proximal tube section together, the distal tube section including an orifice formed therethrough and sized to enable the fluid to enter the distal tube section so that the fluid can flow into and through the distal tube section, the connector and the proximal tube section;

    an insertion device slidably receivable by the tube assembly, the insertion device including an elongated inner alignment rod having a contact end portion and an insertion end portion disposed opposite the contact end portion, the inner alignment rod sized to extend into the tube assembly wherein the contact end portion contacts the closed end of the distal tube section while the insertion end portion projects outwardly from the tube assembly;

    an expandable member disposed circumferentially about and longitudinally along one of the proximal tube section and the insertion device adjacent the connector and operative to move between an expanded state wherein the expandable member expands radially outwardly and a collapsed state wherein the expandable member collapses; and

    an activation device operably connected to the expendable member and disposed externally of the urethra to cause the expandable member to move between the expanded state and the collapsed state.
