A temporary hemostatic plug apparatus for use in a patient includes a plug structure configured to be placed within a patients tubular body structure. The plug structure may be configured to be placed in an incision to create a bloodless operating field for a surgeon to operate, for example to perform an anastomosis. This may be done by deploying the plug structure out from within the lumen to create a hemostatic seal around the incision. Once the surgeon has completed the operation, the plug apparatus may be removed from the lumen through the incision, or through any other point of access in the lumen.
