Participant Flow

10 clinical Sites enrolled and implanted subjects. All subjects gave informed consent prior to enrollment and all implanted subjects met the inclusion / exclusion criteria. Enrollment into the study began in February 2006 and ended April 2007.

Subjects who meet the inclusion / exclusion criteria and were good surgical candidates were enrolled into the single arm study and were eligible to be implanted.

Timeframe: Baseline to 24 Months

Population: Number of subjects that did not have test performed at follow-up visit.

The Incontinence Quality of Life (I-QOL) questionnaire contains 22 items, each with a 5-point Likert-type response scale, evaluating a subject's quality of life with respect to his urinary problems or incontinence. A possible total score can be 0-100, with a higher score meaning less problems.

SECONDARY outcome

Timeframe: Baseline to 24 Months

Population: Number of subjects that did not have test performed at follow-up visit.

The ICIQ-SF questionnaire evaluates the impact of urinary incontinence on quality of life through four questions that evaluate the frequency, severity and impact of urinary incontinence. A set of eight self-diagnosis items related to the causes or situations of urinary incontinence experienced by the subject are also assessed. Scores may range from 0 to 21. Improvement in the subject's quality of life from baseline to follow-up is indicated by a decrease in the ICIQ-SF score.

Timeframe: Baseline and 6 Months Post implant

Population: Number of subjects that did not have test performed at follow-up visit.

Baseline urodynamic measurements including bladder capacity, maximum detrusor pressure, detrusor pressure at maximum flow, and detrusor instability were measured at baseline and at 6-month follow-up.

Population: Number of subjects that did not have test performed at follow-up visit.

Baseline urodynamic measurements including bladder capacity, maximum detrusor pressure, detrusor pressure at maximum flow, and detrusor instability were measured at baseline and at 6-month follow-up. Maximum detrusor pressure is measured during a urodynamic study when tension is applied to the bladder wall (detrusor muscles) by filling the bladder to capacity with saline water and observing the detrusor muscle during filling of the bladder and voiding of the saline water.

Baseline urodynamic measurements including bladder capacity, maximum detrusor pressure, detrusor pressure at maximum flow, and detrusor instability were measured at baseline and at 6-month follow-up. Maximum detrusor pressure is measured during a urodynamic study when tension is applied to the bladder wall (detrusor muscles) by filling the bladder to capacity with saline water and observing the detrusor muscle during filling of the bladder and voiding of the saline water. Pdet at Qmax is the detrusor pressure at maximal flow rate when the bladder is full and the patient begins voiding.

Population: Number of subjects that did not have test performed at follow-up visit.

Baseline urodynamic measurements including bladder capacity, maximum detrusor pressure, detrusor pressure at maximum flow, and detrusor instability were measured at baseline and at 6-month follow-up. Detrusor instability occurs when the detrusor muscle is unstable and spontaneously contracts the bladder. The measure data table shows the mean volume at the start of the urodynamic measurement study for patients with detrusor instability.
