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.</p><p><strong>Results:</strong> 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.</p><p><strong>Conclusions:</strong> Our three novel, remotely controlled AUSs showed promising results that should be confirmed by in-vivo experiments focusing on efficacy and safety.</p>}, number={10}, journal={Canadian Urological Association Journal}, author={Biardeau, Xavier and Hached, Sami and Loutochin, Oleg and Campeau, Lysanne and Sawan, Mohamad and Corcos, Jacques}, year={2017}, month={Oct.}, pages={E396–404} }
