Abstract
A method is disclosed for delivering energy to a region of tissue within a patient's body using a medical treatment system. The medical treatment system comprises an energy delivery device coupled to an energy source and the method includes steps of delivering energy, measuring an energy delivery parameter, determining distance of the energy delivery device from a conductive object and optionally adjusting a position of the energy delivery device based on the determined distance.
Claims27
A method for delivering energy to a region of tissue within a patient's body using a medical treatment system, the medical treatment system comprising an energy delivery device coupled to an energy delivery source, the method comprising the steps of:
- (1) delivering energy through said energy delivery device;
- (2) monitoring an energy delivery parameter associated with the delivery of energy by the medical treatment system;
- (3) detecting one or more errors if one or more values of the energy delivery parameter exceed a predetermined magnitude threshold;
- (4) determining an extent of the errors detected;
- and
- (5) controlling the delivery of energy if the extent of the errors detected exceeds a sensitivity threshold over a predetermined time period.
A method for delivering energy to a region of tissue within a patient's body using a medical treatment system, the medical treatment system comprising a medical device coupled to an energy delivery source, the method comprising:
- (1) delivering energy from a medical device to material within a patient's body;
- (2) measuring an energy delivery parameter while the energy is being delivered;
- (3) detecting at least one error if one or more values of the energy delivery parameter cross a pre-determined threshold;
- (4) upon detection of at least one error, assessing an extent of the at least one error to determine whether the medical device is sufficiently distanced from a conductive object to allow for safe delivery of the energy to the material within the patient's body;
- and
- (5) if the medical device is determined to not be sufficiently distanced from the conductive object, adjusting a position of the medical device and repeating steps (2)-(4) until the medical device is sufficiently distanced from the conductive object.
A method for delivering energy to a region of tissue within a patient's body using a medical treatment system, the medical treatment system comprising a medical device coupled to an energy delivery source, the method comprising the steps of:
- (1) delivering energy from the medical device to a material within a patient's body;
- (2) measuring a return current while the energy is being delivered;
- (3) detecting if the return current exceeds a threshold;
- (4) if the threshold is exceeded, assessing an extent by which the return current exceeds the threshold to determine if the medical device is sufficiently distanced from a conductive object;
- and
- (5) if the medical device is determined to not be sufficiently distanced from the conductive object, adjusting a position of the medical device and repeating steps (2)-(4) until the medical device is sufficiently distanced from the conductive object.
