Abstract: A arteriovenous banding device may include a band comprising a first end and a second end, the band extending circumferentially around a central axis to define a central channel having a first diameter, a housing coupled to the first end of the band and defining a housing slot to accept the second end of the band, wherein the housing is disposed outside of the central channel, a screw disposed within the housing and comprising at least one thread disposed adjacent to or abutting the band; and an actuator coupled to the screw, wherein the actuator causes rotation of the screw which causes the second end of the band to move away from or towards the first end of the band such that the first diameter of the central channel changes.
