Abstract
The present invention relates to an improved urinary catheter for efficiently draining urine from a urinary bladder of a patient. The improved urinary catheter includes a soft tip that is friendly to the urinary bladder. The improved urinary catheter further includes longer drainage port for proper irrigation of the catheter and thus make it simple to use and better tolerability. In addition, the improved urinary catheter also includes a catheter plug allowing the patient to move more freely and use lavatory rather than using a urine bag all the time.

- at least one side wall extending over the helical thread form and configured to support the helical thread form during insertion;
- a balloon located adjacent to the helical thread form and capable of being filled and drained of solution,
- the proximal end comprising:
- a balloon port on one side of the proximal end;
- an anchor for providing support to the urinary catheter;
- a drainage port on another side of the proximal end, wherein the drainage port is longer than the balloon port by 2-10 cm;
