Brief Summary

This clinical investigation is designed as an interventional, prospective, non-randomized, open-label, single arm, multicentric and international study for obtaining CE marking.

The study will be the first performed with the ARTUS® medical device aiming to assess safety and performance and will be composed of three phases:

* pilot phase (with safety analysis on the 10 first included subjects in 3 investigational sites),

* pivotal phase (in up to 16 investigational sites with a follow-up until the 12-month post-device activation visit, including an interim analysis at 3-month post-device activation visit on performance and safety),

* long-term phase (with a long-term follow-up until 10 years post implantation in up to 16 investigational sites).

The objectives is to assess safety and clinical performance of the ARTUS® for the treatment of Stress Urinary Incontinence at short and long-term.

The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.; The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.

Response options consist of dichotomous (Yes/No) scales, as well as 5 and 6- point likert scales.; Scores by dimension: * Erection scale: 0-15 (higher score =higher sexual functioning); * Ejaculation scale: 1-35 (higher score =higher sexual functioning); * Satisfaction scale: 6-30 (higher score =higher level of satisfaction)
