Abstract

This paper presents a new urethral valve to deal with severe urinary incontinence (UI) caused by sphincter injury or dysneuria. This valve consists of a wireless power transfer system and a valve body structure driven by SMA (shape memory alloy) spring. The mechanical model of SMA spring and coupling model of wireless energy transfer are derived. Special attention is also given to the biological effects of electromagnetic filed as the proposed device is powered by wireless power transfer system. This valve is validated by simulation experiment and the models are used to investigate the influence of SMA spring parameters, control parameters and coil parameters on the driving characteristics of the proposed urethral valve.
