Anorectal Malformation Surgical Device

The Anorectal Malformation Surgical Device (AMSD) is a surgical device under development for the use in Anorectal Malformation Surgery. Work on this project began in September 2016, and is still ongoing.

Imperforate Anus is a congenital condition for 2 - 2.5 in 10,000 live births [1]. It is characterized by a baby born without a normal anal opening. Due to this, a surgery must be performed to rectify this condition. Previously, expensive stimulatory devices were employed to see the muscular response of the rectal muscle, after which the surgeon must create the opening at their best judgement. The companies that created these devices have gone out of business, and thus once these existing devices break there is no true replacement.

The goal of this project is to create a cheaper alternative to the existing technology and improve upon the old design. It must stimulate the muscles in a similar manner, as well as read the muscular response and analyze this data; the analysis of the response will yield a precise location at which the surgeon should create the incision.
