Abstract
A minimally invasive coronary anastomosis procedure includes providing an incision in an intercostal space between two ribs of a patient, the incision providing access to a selected anastomosis site on a blocked coronary artery. A spreader device is inserted between the two ribs, the spreader device spreading the two ribs apart to sufficiently widen the incision for the procedure to be performed through the incision. An internal mammary artery is dissected from the thoracic wall, and the heart is pharmaceutically treated to substantially reduce its heartbeat. The blocked coronary artery is clamped at two spaced-apart positions at the selected anastomosis site. The blocked coronary artery is incised, and the dissected internal mammary artery is sutured to the incision at the anastomosis site.
