Safety and Performance of UCon Bar Electrode for the Treatment of Overactive Bladder (OAB) and Bowel Dysfunction (BD)

Официальное название

Safety and Performance of UCon Bar Electrode for the Treatment of Overactive Bladder (OAB) and Bowel Dysfunction (BD) - An Early Feasibility Study

Обзор

UCon is a medical device for treatment of the symptoms of overactive bladder (OAB) and bowel dysfunction (BD). It electrically stimulates the DGN through the skin to obtain modulated behaviour of the bladder/bowel musculature e.g., suppress undesired bladder/bowel activity to relieve the symptoms of the patient. This clinical investigation is designed as a single-arm, prospective, multi-centre, and early feasibility study.

Подробное описание

The overall purpose of the current clinical investigation is to evaluate the medical device with a UCon-Bar Electrode with respect to its initial safety and device performance in a cohort of 40 female patients with OAB/BD over a period of 12 weeks.

The investigation consists of two periods: a screening period and an intervention period.

During the screening period, the participants will be using UCon with a Patch Electrode and complete a 4 week stimulation period at home. The screening period will determine if participants fulfil the criteria to participate in the intervention period.

During the intervention period, the UCon Bar Electrode will be inserted in the clitoral hood. After a recovery period (4-8 weeks), the participants will be using UCon with the Bar Electrode and complete wither a 4 week or a 12 week stimulation period at home.

Вмешательства

• Устройство UCon-Bar
  The participant self-administer electrical stimulation to the dorsal genital nerve (DGN) for either 4 weeks or 12 weeks using UCon with the Bar electrode

Первичные конечные точки

• PRIMARY SAFETY: ratio of participants with successful insertion of the UCon Bar Electrode. [Срок оценки: After 4 weeks and 12 weeks]
• PRIMARY PERFORMANCE: ratio of treatment change [performance] of OAB/BD symptoms [Срок оценки: Change from baseline at 4 weeks and/or 12 weeks]

Вторичные конечные точки (6)

• SECONDARY SAFETY: Characterization, including frequency and severity of adverse events related to the risks and anticipated adverse device effects associated with the use of UCon-Bar Electrode. [Срок оценки: After 4 weeks and 12 weeks]
• SECONDARY PERFORMANCE: ratio of treatment change [performance] of OAB/BD symptoms [Срок оценки: Change from baseline at 4 weeks and/or 12 weeks]
• SECONDARY PERFORMANCE: assess whether participants using UCon Bar Electrode experience a change in their quality of life [Срок оценки: Change from baseline at 4 weeks and/or 12 weeks]
• SECONDARY PERFORMANCE: assess whether participants using UCon Bar Electrode experience an impression of treatment improvement [Срок оценки: After 4 week screening period, 4 weeks, and 12 weeks]
• SECONDARY PERFORMANCE: ratio of participant that accept UCon and DGN stimulation [Device and treatment acceptability of UCon] [Срок оценки: After 4 week screening period, 4 weeks, and 12 weeks]
• Secondary PERFORMANCE: ratio of treatment change [performance] of OAB/BD symptoms during the screening period can be reproduced in the intervention period. [Срок оценки: Change from screening period at 4 weeks and/or 12 weeks]
