Abstract
A securing apparatus for selectively securing an ablating element of an ablation instrument proximate to a targeted region of a biological tissue. The securing apparatus includes a support base affixed to the ablation instrument relative the ablating element, and having a support face adapted to seat against the biological tissue proximate to the ablation element. The support base further defines a passage having one end communicably coupled to a vacuum source and an opposite end terminating at an orifice at the support face. The support face together with the biological tissue forms a hermetic seal thereagainst during operation of the vacuum source to secure the ablation instrument thereagainst. Essentially, the hermetic seal and the vacuum source cooperate to form a vacuum force sufficient to retain the ablation device against the biological tissue.
