Brief Summary:
The purpose of this pivotal study is to illustrate the safety and effectiveness of the StimGuard Sacral Nerve Stimulation (SNS) System in the treatment refractory urge incontinence. This is a prospective, randomized, controlled, multi-center, study in which 92 subjects will receive a StimGuard SNS System.

Condition or disease Intervention/treatment Phase
Urinary Incontinence, Urge Device: StimGuard Sacral Nerve Stimulator System Not Applicable

Detailed Description:

The StimGuard SNS System is utilized for the treatment of refractory urgency urinary incontinence as defined by the International Continence Society (ICS) Standardization of Terminology Committees Joint Report as the observation of involuntary leakage from the urethra synchronous with the sensation of a sudden, compelling desire to void that is difficult to defer. The system provides treatment by delivering small controlled electrical pulses to the sacral nerves, as these nerves have been shown to regulate the micturition cycle.

In this study, subjects will be randomized into one of two groups with a 1:1 ratio after enrollment. Subjects will either be randomized to an immediate or a delayed activation group. An intraoperative test will be performed, and all subjects will receive a permanent implant if they have an appropriate motor nerve root response without significant discomfort at 5 mA amplitude or less.

Arm Intervention/treatment
Experimental: Immediate Activation
Subjects randomized to this group will have the StimGuard Sacral Nerve Stimulator System activated immediately.
Device: StimGuard Sacral Nerve Stimulator System
The StimGuard Sacral Nerve Stimulator System is a wirelessly powered neurostimulator for urge urinary incontinence. This technology includes a quadripolar stimulator with an embedded receiver. The energy source is a small, external, rechargeable transmitter, which is worn by the patient. The transmitter sends the therapy program and power through the skin and to the receiver.

Delayed Activation
Subjects randomized to this group will have the StimGuard Sacral Nerve Stimulator System activated after 90 days.
Device: StimGuard Sacral Nerve Stimulator System
The StimGuard Sacral Nerve Stimulator System is a wirelessly powered neurostimulator for urge urinary incontinence. This technology includes a quadripolar stimulator with an embedded receiver. The energy source is a small, external, rechargeable transmitter, which is worn by the patient. The transmitter sends the therapy program and power through the skin and to the receiver.




Primary Outcome Measures :
  1. Reduction in number of urge related incontinence episodes [ Time Frame: 3 Months ]
    Self reported on a 3-day voiding diary

  2. Incidence and severity of adverse events [ Time Frame: Up to 12 months ]

Secondary Outcome Measures :
  1. Proportion of subjects with a reduction in the degree of urgency as measured by PPIUS [ Time Frame: 3 Months ]
    Self reported on a 3-day voiding diary

  2. Proportion of subjects with a reduction in the number of voids compared to baseline [ Time Frame: 3 Months ]
    Self reported on a 3-day voiding diary

  3. Improved quality of life function via the Incontinence Quality of Life Scale (I-QOL) [ Time Frame: 3 Months ]
    Quesionnaire


Other Outcome Measures:
  1. Proportion of subjects dry [ Time Frame: 12 months ]
    Self reported on a 3-day voiding diary

  2. Number of Episodes associated with urge [ Time Frame: 12 months ]
    Self reported on a 3-day voiding diary

  3. Proportion of subjects reporting improvement [ Time Frame: 12 Months ]
    Measured by Global Response Assessment as "moderately" or "markedly improved"

  4. Improved quality of life function via Overactive Bladder Questionnaire (OAB-Q) [ Time Frame: 12 Months ]
    Questionnaire

  5. Improved quality of life function via Idiopathic Overactive Bladder Symptom Score (iOABSS) [ Time Frame: 12 Months ]
    Questionnaire
