Apparatus and methods for treating female urinary incontinence

Apparatus for remodeling at least one treatment site within the lower urinary tract of a female patient, the lower urinary tract including a urethra having a urethral lumen and a bladder having a bladder outlet, the apparatus comprising:

• an elongated shaft having proximal and distal ends;
• a handle coupled to the proximal end of the elongated shaft and configured to rotate the shaft when the shaft is inserted into the urinary tract;
• a plurality of electrodes spaced circumferentially in a single plane around the shaft, the electrodes configured to be deployed from the shaft, retracted back into the shaft, and redeployed after rotation of the shaft to treat a submucosal layer of the urethra or bladder outlet to cause a reduction in the compliance of the submucosal layer;
• an expandable member attached to the distal end of the elongated shaft, the expandable member adapted to be deployed in the bladder and be anchored against the bladder outlet;
• and
• a plurality of measurement markers on the shaft, each marker extending around part of a circumference of the shaft, the measurement markers configured to indicate a depth of the shaft within the lower urinary tract.
