ABSTRACT:
A coronary artery graft flow-meter apparatus for insertion into a delivery line for solution to be perfused through a graft after the graft is anastomosed to a coronary artery is disclosed. The apparatus comprises a flow-meter chamber having an upper end and a lower end, the upper end having an inflow port and the lower end having an outflow port. The chamber includes a plastic bag positioned therein which is adapted to communicate with a volumetric container containing the solution. The solution flows from the volumetric container to the plastic bag thereby providing a measurement of the flow rate of the solution through the graft.
