The present invention provides medical devices and methods for suturing tissue by proximally drawing sutures (138) through a tissue layer (30) in the proximity of an aperture (fig. 20); suturing vascular tissue while maintaining adequate perfusion or hemostasis, or both; anastomosing a graft (114) to an aperture in a vessel wall while maintaining hemostasis at the anastomosis with physiological flow and/or pressure in the vessel lumen; punching and removing tissue (36) to form an aperture in a vessel wall while maintaining hemostasis at the aperture with physiological flow and/or pressure in the vessel lumen (fig. 13); automatically and repeatedly placing suture thread through vessel wall tissue surrounding an aperture in the vessel wall in a suture pattern that is useful for anastomosing a tubular graft (114) to the aperture; and, deploying a suture with one end extending through the tissue that surrounds a punched aperture in a vessel wall and the opposite suture end extending radially through a tubular graft wall adjacent an open end of the graft, such that a vessel anastomosis may be rapidly and repeatedly performed in a CABG procedure even while the vessel is under physiological flow.
