Abstract
Hollow body structures may be manipulated and dissected from surrounding tissue using a manipulator device and a dissection device, The manipulator includes a rigid shaft having an inflatable balloon at its distal end. By inserting the balloon through a wall of the body structure and inflating the balloon, the body structure can be manipulated using the shaft to expose a dissection plane in an optimum manner. The dissection device is used to separate the body structure from its surrounding tissue. The separator device includes a separator head which is a cylindrical body having a plurality of axial channels therein. The dissector head is rotated or oscillated at a high frequency and acts to separate the body structure from the surrounding tissue with minimum damage.
