Abstract: Systems and methods for monitoring a bypass device for protecting an intestinal anastomosis are provided. The system includes a pump, one or more fluid inlet lines fluidically coupled to the pump and to a negative pressure chamber of the bypass device, and one or more sensors configured to measure data indicative of pressure within the negative pressure chamber. A controller operatively coupled to the pump and the one or more sensors may be programmed to actuate the pump to generate a vacuum within the negative pressure chamber to thereby pull intestinal tissue towards the bypass device to anchor the bypass device at a target location upstream of the intestinal anastomosis. The controller further may compare the pressure within the negative pressure chamber with a predetermined pressure range and, if the pressure falls outside the predetermined pressure range, adjust the pump to maintain the vacuum within the predetermined pressure range.
