Perfusion device for maintaining blood flow in a vessel while isolating an anastomosis |
摘要 |
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. A selected portion or portions of the device's outer circumference fit snugly within the artery in the regions beyond and/or at the anastomosis site, to maintain the latter free of blood. Several methods for deploying and removing respective embodiments of the device also are illustrated.
