Abstract: A method and system for mapping tissue and producing lesions for the treatment of cardiac arrhythmias in a non-thermal and optimal manner, minimizing the amount of energy required to selectively stun or ablate the target tissues. Energy may be delivered only at the moment(s) of best device position and proximity of an electrode to target tissue, and only during a time in the cardiac cycle determined to be optimal for reversible or irreversible effects. A method may include determining timing of the cardiac cycle and an optimal time within the cardiac cycle for energy delivery, evaluating proximity between at least one energy delivery electrode and the target tissue, and delivering pulsed field energy from the at least one energy delivery electrode to the target tissue when, during the optimal time for energy delivery, the at least one energy delivery electrode is in close proximity with the target tissue.

Abstract: The present disclosure relates to devices, systems and methods for evaluating the success of a treatment applied to tissue in a patient, such as a radio frequency ablative treatment used to neuromodulate nerves associated with the renal artery. A system monitors parameters or values generated during the course of a treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of the likelihood that a completed treatment was technically successful. In other embodiments, parameters or values generated during the course of an incomplete treatment (such as due to high temperature or high impedance conditions) may be evaluated to provide additional instructions or feedback to an operator.

Abstract: A medical system for delivering treatment or therapy to a patient has a kill switch for interrupting the delivery. The kill switch, which can disrupt the delivery directly or can cause an error message to be generated that disrupts the delivery, can be activated by the operator or remotely. In an ablation catheter system, a kill switch mechanism immediately and abruptly terminates delivery of ablation treatment or therapy.

Abstract: A system for providing irrigation fluid during ablation of tissue includes a catheter, an electrode assembly, at least one thermal sensor adapted to be connected to the catheter, and a control system. The electrode assembly is adapted to be connected to an ablation generator. The thermal sensor is adapted to be operatively connected to an electronic control unit (ECU). The ECU receives as an input temperature measurement data from the thermal sensor; determines a power delivery rate value for the ablation generator responsive to the temperature measurement data; and outputs the power delivery rate value. The control system also delivers irrigation fluid to the irrigated catheter at a first flow rate in a first time period and at a second flow rate in a second time period that is temporally after the first time period. The second flow rate is at least half of the first flow rate.

Abstract: Body tissue ablation is carried out by inserting a probe into a body of a living subject, urging the probe into contact with a tissue in the body, generating energy at a power output level, and transmitting the generated energy into the tissue via the probe. While transmitting the generated energy the ablation is further carried out by determining a measured temperature of the tissue and a measured power level of the transmitted energy, and controlling the power output level responsively to a function of the measured temperature and the measured power level. Related apparatus for carrying out the ablation is also described.

Abstract: A surgical instrument includes an end effector including first and second jaw members movable relative to one another between a first, spaced-apart position and a second position proximate tissue. In the second position, the jaw members cooperate to grasp tissue therebetween. A first optical fiber is disposed within the first jaw member and is configured to provide a first signal, and a second optical fiber is disposed within the first jaw member and is configured to provide a second signal. A controller is coupled to the first and second fibers and is configured to determine the temperature and the strain of the first jaw member as a function of the first and second signals, respectively.
