The Vessel Cannula is indicated for use in delivery of cardioplegia solution during cardiopulmonary bypass surgery, or to help check for leaks in a harvested vein which will be used for a graft. The Vessel Cannula is a flexible, tapered, polyvinyl chloride tube with a soft distal tip. The distal tip has two sizes of anchor hubs (3mm distal - 3.6mm proximal) designed to accommodate vessels of various diameters. The proximal female luer connection is designed to securely connect with a standard cardioplegia delivery line.
