Abstract
The subject matter of this specification can be embodied in, among other things, an indwelling catheter with an integrated coil section. The coil section, in use, is disposed outside of the urethra and can stretch and bend to accommodate various activities of a user by reducing frictional forces and trauma within the urethra. This improved catheter design results in an increase in range of motion and a decrease in pain for the user.
Claims16
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.

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.
