Definitions

  • the present invention relates generally to devices and methods for treating female urinary incontinence. More particularly, the present invention relates to intraurethral devices and methods for controlling urine flow.
  • a bladder flow control device may be positioned in the urethra of a patient to control the flow of urine out of the bladder. It is desirable for the placement of the bladder flow control apparatus in the urethra to be performed easily and non-surgically. Once the bladder flow control device is placed, it is desirable that it be safely and securely retained in the urethra. Optimally, the device surfaces which contact the human body will be formed of biocompatible materials, to lessen chances of inflammation in patients.
