Methods and devices for blood vessel harvesting

摘要

Methods and devices for harvesting veins or other elongate structures from the body are disclosed. The disclosed methods and devices allow vein harvesting using endoscopic procedures. A working space is created over a vein using standard endoscopic procedures and a side-hooked wire is inserted into the working space and twisted to insert the side-hook under the vein. The wire is then pulled or drawn along the vein to separate the vein from the surrounding tissue. In an alternative embodiment, vein separation is accomplished by threading a soft rubber tube under the vein, and then pulling the tube along the vein. In other embodiments, the working space is created with everting balloons.
