ELECTROSURGICAL SPHINCTER TREATMENT APPARATUS

摘要

A sphincter treatment apparatus includes an introduction member to be introduced through the oesophagus, the member having at its distal end an expandible basket consisting of a plurality of flexible arms, the basket being introduced through the sphincter and then mechanically expanded to dilate the sphincter. The basket has sensing electrodes to detect myoelectric potentials, and hosts a number of energy delivering electrodes, needle shaped, that can exit the basket arms to be deployed into the sphincter muscle for treatment. Cooliant and electrolyte can be used.
