1. An instrument for dissecting and cauterizing in an interior of a body comprising:

  • an elongate probe member extending along a longitudinal axis;

    an inflatable structure having an inflation chamber and carried around a distal portion of said probe member and in a contracted state having a diameter about equal to the diameter of said probe member and in an expanded state having a greater transverse dimension than that of said contracted state;

    an inflation mechanism operatively connected to said inflation chamber thereby to inflate and deflate said inflatable structure between said contracted state and said expanded state; and

    an electro-cautery grid comprising a plurality of electrodes carried around an exterior of said inflatable structure, said electrodes operatively connected to an electrical source, said electro-cautery grid being adapted for cauterizing dissected blood vessels;

    wherein in said contracted state said electrodes are in an at least partly radial pattern, so that in said expanded state, said at least partly radial pattern is expanded by said inflatable structure to a straightened longitudinal pattern.
