Abstract:
A securing apparatus for selectively securing an ablating element of an ablation instrument proximate to a targeted region of a biological tissue comprising:a support base adapted to affix to said ablation instrument relative said ablating element, and having a support face adapted to seat against the biological tissue proximate to the ablation element, said support face defining a window portion configured to cooperate with the ablating element of the ablation instrument to direct a majority of an ablating field of the ablating element generally in a predetermined direction, said support base further defining a passage having one end communicably coupled to a vacuum source and an opposite end terminating at the support face at a proximal orifice positioned on a proximal end of said window portion, and at a distal orifice positioned on a distal end of said window portion; wherein said support face forms a hermetic seal against the biological tissue during operation of said vacuum source to secure the ablation instrument thereagainst.
