Claim 0:
1. An indwelling catheter comprising:
an elongated catheter main body defining:
a first section that is configured to be inserted into a urethra of a human patient through a urethral opening;
a second section comprising one or more ports and is 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 is configured to be disposed outside of the urethra proximal to the urethral opening, the flexible coil section has a longitudinal length of approximately 2 to 2.25 inches in a contracted position and approximately 4.25 inches in a stretched position, and extends from a distal end at the second section to a proximal end at the first section, and the proximal end is configured to be directly adjacent to the urethra opening of the urethra when the first section is arranged within the urethra,

wherein the flexible coil section is configured to expand and bend based on a kinetic energy of an external force applied to the second section and the flexible coil section due to a range of motion of the human patient, 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.
