  • Perfusion device for maintaining blood flow in a vessel while isolating an anastomosis
    Patent number: 6214022
    Abstract: A plurality of embodiments of a distal perfusion device are disclosed, which device facilitates anastomosis constructions by maintaining a dry anastomosis site while simultaneously maintaining blood flow distally in the blood vessel to prevent ischemia and reduce overall patient trauma. The perfusion device is configured for installation into a blood vessel such as a left anterior descending coronary artery through an incision therein, to which is to be grafted a distal end of a blood vessel such as an internal mammary artery. The device includes a central member of selected configuration and material, terminating at either end thereof in respective selectively tapered end members. A lumen extending through the central member and end members, and selected perforations in the end members, maintain blood flow through the perfusion device.
    Type: Grant
    Filed: April 28, 1999
