A surgical instrument comprises a handle connected to a shaft and a pair
of inflatable members. The shaft includes conduits for communicating a
pressurized medium to the inflatable members and an insufflation tube.
The handle includes a port for communicating a pressurized medium to the
conduits and a port for communicating a pressurized medium to the
insufflation tube. After an anastomotic ring has been deployed, the shaft
may be positioned such that an inflatable member is positioned within
each of the lumens joined by the anastomosis, such that an inflatable
member is located on each side of the anastomosis. The inflatable members
may be inflated to provide a seal in each of the lumens. With each of the
lumens sealed by the inflatable members, the anastomosis site may be
insufflated through the insufflation tube to leak or pressure test the
anastomosis.
