    摘要： Methods and devices for harvesting veins from the body. The methods and devices allow vein harvesting using laparoscopic procedures. A working space is created over the vein using standard laparoscopic 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, grasping the ends of the tube so as to surround the vein, and then pulling the tube along the vein. In other embodiments, the working space is created with everting balloons.

    摘要： The present invention comprises a tubular shunt for insertion into a fluid vessel in a living creature constructed of an elastically deformable material that reduces in circumference when stretched longitudinally so that the ends of the shunt may be easily inserted into openings in a blood vessel and where the material expands circumferentially when allowed to axially contract such that the ends of shunt press against the vessel wall to secure the shunt and form a water tight seal to permit fluid to flow through the tubular conduit of the shunt. A method for shunting fluid-flow in a portion of a vessel in a living creature is also disclosed wherein a shunt of the present invention is stretched longitudinally so that the ends of the shunt contract and then inserted into a lumen of a blood vessel. Following insertion of the shunt, the shunt is allowed to return to its relaxed geometry so that it forms a fluid tight seal with the interior of the lumen.
