  6. Ability and willingness to self-catheterize in case this is necessary
  7. Bladder Diary Criteria: over the 3 days the following outcomes:

Subjects will be excluded if ANY of the following conditions apply:

  1. Planning on becoming pregnant during the 18 month study period
  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

  5. Ongoing complications of prior anti-incontinence surgery
  6. SNS or PTNS treatment within the last 15 days. NOTE: a SNS device that is not turned on is acceptable for enrollment
  7. Botox treatment for OAB with 100u in the last 6 months OR Botox treatment with >100u in last 9 months.
  8. Subject with 24-hour total urine volume voided greater than 3,000 ml as measured at screening period
  9. Urinary tract infection that is not resolved at the time of enrollment or had > 3 urinary tract infections (UTIs) within the last 12 months NOTE: If UTI is present at baseline screening, treatment with antibiotics and a negative urinalysis at least 7 days after the initial diagnosis of UTI will be acceptable for enrollment.
  10. Documented spontaneous unprovoked urinary retention within the last 6 months

Anatomical conditions or surgical implants that, in the opinion of the investigator, would preclude the introduction and/or use of the device such as significant pelvic organ prolapse, urogenital prolapse visible at rest beyond the hymen, significant cystocele prolapse, implanted vaginal mesh between the trigone of the bladder and vagina or high BMI.
  12. Current hydronephrosis or hydroureter
  13. Current bleeding disorder or coagulopathies
  14. Current use of antimuscarinics, β3 agonist or antispasmodics NOTE: subjects on these drugs must undergo a 2 week washout period prior to completing the baseline Bladder Diary.

  16. Previous pelvic irradiation
  17. Serum creatinine or BUN > twice the upper limit of normal within the last sixty days
