  • Devices and systems for treatment of urinary incontinence, and methods of making and using same
    Patent number: 11903806
    Abstract: An artificial urinary sphincter can include a cuff configured to surround a portion of a length of a urethra. An actuator is configured to selectively apply a force to the cuff to thereby apply variable amount of pressure to the urethra. A controller is configured to adjust the application of the force by the actuator to cause the cuff to apply the variable amount of pressure to the urethra. A sensor can be in communication with the controller and configured to detect pressure applied against the cuff by the urethra. The controller is configured to cause the cuff to apply a first closing pressure to the urethra. In response to a detection of a threshold pressure increase by the sensor, the controller is configured to cause the cuff to apply a second closing pressure that is greater than the first closing pressure and that prevents urine from exiting the urethra.
