Abstract
A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter, a longitudinal axis, and a sharp distal end. An insulating member extends through the hollow needle and is movable relative to the hollow needle. An elongated member extends through the insulating member and is movable relative to both the insulating member and the hollow needle. A resilient wire projects from the elongated member and is retractable within and extendable outside of the insulating member and the hollow needle. The insulating member, elongated member, and resilient wire are movable relative to the needle using first and second moving means whereby the surgical assembly assumes various configurations having different operational functions.
