An apparatus comprises a first longitudinal member and a second longitudinal member configured to be located near a tissue region. An energy source is coupled to first longitudinal member and second longitudinal member. A measuring device is configured to measure at least one characteristic of the tissue region. An energy controller is coupled to the energy source and the measuring device. The energy controller includes a processor coupled to a memory and configured to execute programmed instructions stored in the memory, comprising initiating a delivery of energy to the tissue region from the energy source. One or more items of data are received from the measuring device based on the delivery of energy to the tissue region. The delivery of energy to the tissue region is adjusted based on the one or more items of data.

Methods for tissue ablation measurement and control and devices thereof

A method and apparatus for measuring an impedance of a tissue region inside a body of a patient. A first guidewire is advanced into a tissue region of a body of a patient, wherein the first guidewire comprises one or more electrodes electrically coupled to the tissue region. A second guidewire is advanced into the body, wherein the second guidewire comprises one or more electrodes electrically coupled to the tissue region of the body of the patient and spaced from the first guidewire. An error correction electrode is electrically coupled to the body. A voltage is applied across the first and the second guidewires. The impedance of the tissue region between the first and the second guidewires is measured while using an electrical pathway created by the error correction electrode.
