Claim 1
Independent Claim
188 words
A method of evaluating tissue changes in a mammal occurring as a result of applying a therapeutic hyperthermia treatment to a volume of tissue of said mammal, comprising: a) placing electrodes on, near or into a volume of tissue to be monitored; b) applying therapeutic hyperthermia to the volume of tissue desired to be heated; c) measuring the electrical impedance of the volume of tissue to be monitored at least twice by means of the electrodes and by impedance measurement means in order to measure frequency dependent changes in the measured electrical impedance; d) employing the frequency dependent changes in the measured electrical impedance to evaluate physiological and histological changes in the tissue cells, thereby measuring the nature and extent of the tissue changes; and e) employing the measurements obtained from the tissue changes as a predictive assay of the progress of the hyperthermia treatment, thereby employing the same as an aid in adjusting the administration of the treatment, or determining a prognosis for each treatment, or ascertaining the desired stopping point for each treatment, or determining the need for further treatment or any combination of the above.
Claim 2
Independent Claim
188 words
A method of evaluating tissue changes in a mammal occurring as a result of applying a therapeutic hyperthermia treatment to a volume of tissue of said mammal, comprising: a) placing electrodes on, near or into a volume of tissue to be monitored; b) applying therapeutic hyperthermia to the volume of tissue desired to be heated; c) measuring the electrical impedance of the volume of tissue to be monitored at least twice by means of the electrodes and by impedance measurement means in order to measure frequency dependent changes in the measured electrical impedance; d) employing the frequency dependent changes in the measured electrical impedance to evaluate physiological and histological changes in the tissue cells, thereby measuring the nature and extent of the tissue changes; and e) employing the measurements obtained from the tissue changes as a predictive assay of the progress of the hyperthermia treatment, thereby employing the same as an aid in adjusting the administration of the treatment, or determining a prognosis for each treatment, or ascertaining the desired stopping point for each treatment, or determining the need for further treatment or any combination of the above.
