ABSTRACT:
A conductive cannula assembly is disclosed to dissipate possible, accumulated electrical charges through body tissue. The cannula assembly includes cannula housing means and cannula means formed of a material having an electrical conductivity value which is at least fifty percent the conductivity value of silver. The invention also includes cannula assembly accessories formed of a material having an electrical conductivity value which is at least fifty percent the conductivity value of silver. The invention further provides a method for guiding endoscopic instruments into body tissue utilizing the cannula assembly and the cannula assembly accessories of the present invention.
