ABSTRACT:
A retractor and a surgical tool are positioned at the distal end of the cannula. A dissection cradle is located at the distal end of a distal portion of the retractor that is resiliently skewed relative to the cannula axis, and includes two substantially parallel, spaced legs with the retractor shaped in a loop therebetween. The procedure includes locating a vessel and side branch of interest and extending the retractor to retain the vessel in the dissection cradle to urge the vessel away from the axis of the cannula in order to isolate a side branch for exposure to the surgical tool.
