Subject has had any spinal or genitourinary surgery within the last 6 months. 9. Subject had previous abdominoperineal resection of the rectum or radical hysterectomy (female)/ prostatectomy (male). 10. Subject with diagnosis of BPH with outflow/obstructive predominant symptoms. 11. Subject has skin, peripheral edema, orthopedic or neurologic anatomical limitations that preclude implantation or/and use of the device. 12. Subject with Alzheimer's, Parkinson, MS, stroke (CVI), neuropathy or injury resulting in neuropathy and/or suspected neurogenic bladder. 13. Subject has recurrent urinary tract infections (3 or more infections in the last 6 months), or presence of urinary fistula, or urinary tract obstruction such as cancer, urethral stricture or presence of urinary stone. 14. Subject with history of chemotherapy or pelvic radiotherapy that might have affected bladder control or caused neuropathies (i.e. peripheral neuropathy). 15. Male subject who have obstructive Benign Prostatic Hyperplasia (BPH) or other lower urinary tract obstructions. 16. Subject has open wounds or sores on the lower leg or foot or had previous, unhealed trauma in the implant area or has pitting edema (≥2+) in the lower leg. 17. Subject has Venous or Arterial disease/insufficiency in the lower leg or Vasculitis or dermatologic condition in the lower leg or infections near the implantation site in the lower leg. 18. Subject has a documented history of allergic response to Platinum iridium, Titanium, Zirconia, Gold, Silicone or Parylene. 19. Subject has other active implantable electronic device/s regardless of whether stimulation is ON or OFF. 20. Subject has a life expectancy of less than 1 year.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|

Other Device: Revi System Treatment Arm |
Subjects will be implanted with a Revi System and activation of therapy will occur ~4 weeks post implantation and continue for the duration of the study. |
|
|
Other Device: Revi System - Delayed Activation Control Arm |
Subjects will be implanted with a Revi System and activation of therapy will be delayed until 4 months post implantation. At this time the Revi System will be activated to begin therapy and will continue for the duration of the study. |

Detailed Description
Prospective, multi-center, open label, post market, randomized controlled trial To demonstrate superiority of Revi System therapy vs. non active therapy in the treatment of UUI Treatment Arm: Device: Revi System Subjects will be implanted with a Revi System and activation of therapy will occur ~4 weeks post implantation and continue for the duration of the study. Control Arm: Device: Revi System - Delayed Activation Subjects will be implanted with a Revi System and activation of therapy will be delayed until 4 months post implantation. At this time the Revi System will be activated to begin therapy and will continue for the duration of the study. Randomization in a 1:2 ratio into either the "control group" or the "treatment group" will be performed in blocks of 3 or 6 randomly, across the study population by a central randomization system. Randomization will be stratified by investigational site. The study will consist of the following activities: Visit 1 - Screening - Potential subjects with UUI, who fulfil basic criteria will be informed of the study and will be invited to sign an informed consent form. - Demographic information (age, race, height and weight, leg circumference), medical and surgical history and concomitant medication information will be collected. - Study candidates will be asked to fill out various questionnaires - Patients will be asked to complete a 3- consecutive day voiding diary. - Urine sample will be collected, blood will be drawn and a full physical examination, including a PVR measurement and uroflow (in men), will be performed. Visit 2 - Randomization & Implantation - 5 ± 4 weeks after starting the diary, eligible subjects will be randomized to either the Treatment or Control (delayed activation) arms (2:1) and will undergo unilateral implantation with the BlueWind Revi System - Collection of AE and concomitant medication will be performed Treatment Arm: Visit 3 - Activation - After a recovery period of 4-weeks post implantation, subjects will attend the clinic to undergo physical examination and surgical wound check-up. - Subjects will undergo parameter setting according to the individual patient sensations and will be trained on the use of the system. Visits 4-11 - Treatment optimization and follow up - Follow-up visits will be performed at 1, 2, 3, 6, 9, 12, and 24 months post system activation. - A call visit will be performed at 18-months. - All follow-up visits will require completion of a 3-day voiding diary by the patient before coming to the visit. - During each clinic visit, stimulation parameters and level of treatment will be checked and adjusted as needed. Control Arm: • After a recovery period of 1-month post implantation, subjects will attend the clinic to undergo physical examination and surgical wound check-up. Visit 4 - Activation - After a recovery period of 4-weeks post implantation, subjects will attend the clinic to undergo physical examination and surgical wound check-up. - Subjects will undergo parameter setting according to the individual patient sensations and will be trained on the use of the system. Visits 5-12 - Treatment optimization and follow up - Follow-up visits will be performed at 1, 2, 3, 6, 9, 12, and 24 months post system activation. - A call visit will be performed at 18-months. - All follow-up visits will require completion of a 3-day voiding diary by the patient before coming to the visit. - During each clinic visit, stimulation parameters and level of treatment will be checked and adjusted as needed.
