Abstract: A urinary catheter device having a means for unblocking the catheter includes a tube, which has a distal end that is closed. The tube is resilient and is configured to insert through a urethra of an animal to position the distal end in a bladder. A hole is positioned through a wall of the tube proximate to the distal end and is configured to drain urine from the bladder through a proximal end of the tube, which is open. A channel extends through the wall from a first valve that is coupled to the tube to a chamber that is positioned in the wall proximate to the hole. Introduction of a fluid via the first valve into the chamber expands the chamber and increases a circumference of the hole so that debris that is impeding a flow of the urine through the tube enters and passes through the tube.
