Abstract
The novel artificial puborectalis anal sphincter (APAS) system this article presented is a novel implantable system, and could treat severe fecal incontinence (FI) caused by multiple reasons. The system controls defecation by forming the anorectal angle, which makes it possible to remodel rectal function. Pressure sensors are set in system to monitors the pressure of intestinal canal, and help to prevent the happening of ischemia tissue necrosis. To satisfy the long term energy supply, transcutaneous energy transfer system is adopted. At last, to estimate performance of the optimized in situ implantable artificial puborectalis anal sphincter system, an in vivo experiment was designed. The completion of in vivo experiment verified the implant ability of the novel in situ implantable artificial puborectalis anal sphincter system and its basic function. The results of experiment indicate that the system is a good device to control fecal incontinence and rebuild rectal perception. It might become a new treatment in excretion control in situ for fecal incontinence and rectal cancers after anus-retained operation.
