OLDER_ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: All subjects will be implanted with the device and randomized (2:1) to ON vs OFF. After the subjects complete the OFF period, their system will be activated and they will crossover to the ON group.
Primary purpose: TREATMENT

Brief summary: The Revi System is indicated for the treatment of patients with symptoms of urgency incontinence alone or in combination with urinary urgency.

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.
