ABSTRACT:
This invention relates to a method for the dissection of blood vessels, lymph nodes and other body organs from the surrounding tissue and to a novel balloon dissection instrument for use in the method. The dissection instrument comprises an elongated tube having at least one inflatable balloon attached around the outer wall of a distal portion of the tube. The method of dissecting a vein, such as the saphenous vein, involves severing of the vein at two sites, defining the length of vein to be dissected. The vein is then accessed by securing the severed end, for example by a thread attached thereto and passed through the lumen of the dissection instrument to serve as a controllable anchor. The distal end of the dissection instrument, with the balloon deflated, is placed over the free end of the vein so that the vein enters the lumen of the instrument and the distal end of the instrument is pressed between the outer layer of the vein, i.e., the adventitia, and the connected fascia. The balloon is then inflated causing the adventitia and fascia to separate in the region proximate to the distal end of the instrument. The balloon is then deflated and the instrument moved forward to encompass the dissected portion of vein within the lumen of the instrument. The balloon is again inflated to free another section of the vein from the surrounding fascia. The procedure is repeated and the instrument advanced along the length of the vein until the desired length of vein has been dissected.
