Claim 12:
13. A method of catheterization comprising:
inserting a first section of an elongated catheter main body into a urethral opening of a urethra of a human patient through a urethral opening, the elongated catheter main body comprising:
the first section that is configured to be inserted into the urethra of the human patient through the urethral opening;
a second section comprising one or more ports and configured to be disposed outside of the urethra; and
a flexible coil section that is disposed between the first section and the second section and configured to expand and bend based on a kinetic energy of external forces applied to the second section and the flexible coil section due to a range of motion of the human patient, and contract toward a contracted position in a relaxed state based on a relaxation of the range of motion of the human patient, and absorb, by expansion and contraction, the kinetic energy, the flexible coil section having a longitudinal length of approximately 2 to 2.25 inches in a contracted configuration and approximately 4.25 inches in an expanded configuration; and

inserting the first section through the urethra such that the first section extends to a bladder of the human patient and the flexible coil section disposed outside of the urethra directly adjacent to the urethral opening.
