“…Indeed, the current AMS800™ device was marketed since 1983 and has never submitted to major improvements since then. A total of nine hydro‐mechanical or purely mechanical AUSs have been reportedly developed at the time of our literature review . Three of them have already been implanted and studied in humans, but none has yet been directly compared to the AMS800™.…”

“…A device, which could be easily manipulated, would allow implantation in less skillful patients who currently cannot benefit from the AMS800™. This could be accomplished by remotely controlled AUSs, as proposed recently . Furthermore, easy AUS deactivation could also improve efficacy and safety.…”

Artificial Sphincters to Manage Urinary Incontinence: A Review

et al. 2018

View full text Add to dashboard Cite

Urinary incontinence affects more than 300 million people worldwide. The implantation of a medical device called an artificial urinary sphincter (AUS) is the gold standard treatment when conservative and minimally invasive therapies fail. In this article, the AUSs (extra-urethral and endo-urethral sphincters) available on the market, both presented at the research level and filed as patents, are reviewed. The ability of the different solutions to effectively replace the natural sphincter are discussed, together with advantages and some possible side effects, such as tissue atrophy, overall invasiveness of the implant, and so forth. Finally, future research priorities are discussed for both endo-urethral and extra-urethral approaches considering key engineering aspects, such as materials, compression and closure mechanisms, and implantation methods, with the long-term aim of developing an effective, reliable, durable, and minimally invasive AUS capable of restoring a normal quality of life for incontinent patients.

“…Data on our prototype pressure regulation hardware -the wireless connection device and different energy supply systems -have already been reported recently in engineering journals. [14][15][16] In the present article, we describe these three distinctly developed systems from clinicians' viewpoints and in a language accessible to non-engineers. We focus mainly on pressure issues associated with each of them in in-vitro and ex-vivo experiments.…”

Introduction: We aimed to present three novel remotely controlled hydromechanical artificial urinary sphincters (AUSs) and report their in-vitro and ex-vivo results. Methods: We successively developed three distinct hydromechanical AUSs on the basis of the existing AMS800 ™ device by incorporating an electronic pump. No changes were made to the cuff and balloon. The AUS#1 was designed as an electromagnetically controlled device. The AUS#2 and AUS#3 were conceived as Bluetooth 2.1 remotely controlled and Bluetooth 4.0 remotelycontrolled, adaptive devices, respectively. In-vitro experiments profiled occlusive cuff pressure (OCP) during a complete device cycle, with different predetermined OCP. Ex-vivo experiments were performed on a fresh pig bladder with 4 cm cuff placed around the urethra. Leak point pressure with different predetermined OCP values was successively measured during cystometry via a catheter at the bladder dome. Results: Our in-vitro and ex-vivo experiments demonstrated that these three novel AUSs provided stable and predetermined OCP -within the physiological range -and completely deflated the cuff, when required, in a limited time compatible with physiological voiding cycles. Conclusions: Our three novel, remotely controlled AUSs showed promising results that should be confirmed by in-vivo experiments focusing on efficacy and safety.
