2. Current participation in any other conflicting interventional or OAB treatment study

3. Primary complaint of stress urinary incontinence or stress predominant mixed
incontinence or functional incontinence

4. Any invasive or surgical intervention (e.g., radio frequency, implant, sling)
involving the bladder, rectum or vaginal wall within the last 6 months

5. Ongoing complications of prior anti-incontinence surgery

screening period

7. Receiving electro-stimulation (e.g. PTNS or SNS) treatment within the last 15 days.

NOTE: Subjects with an implanted SNS device that has not been active in the last 15

the opinion of the investigator, such as significant pelvic organ prolapse, urogenital
prolapse visible at rest beyond the hymen, significant cystocele prolapse or high BMI

12. Current bleeding disorder or coagulopathies

13. Current use of antimuscarinics, ß3 agonist or antispasmodics NOTE: subjects on these
drugs must undergo a 2 week washout period prior to completing the baseline Bladder
Diary.

14. Subject has been previously diagnosed with interstitial cystitis, bladder cancer or
chronic pelvic pain syndrome.
