摘要： A method for treating an infection using irreversible electroporation is presented. The method includes providing an ablation device that has at least one electrode and inserting the ablation device into a target tissue of a patient. The tissue at least partially surrounds the implanted medical device. The outer surface of the medical device is at least partially covered by infectious cells. The method also involves positioning at least one electrode in or near the implanted medical device and delivering electrical pulses to or near the implanted medical device sufficient to irreversibly electroporate the infectious cells.

摘要： Systems and methods for neuromodulation therapy are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a plurality of reference electrodes at the skin of a human patient and intravascularly positioning a plurality of ablation electrodes within a blood vessel lumen at a treatment site. The method can include obtaining impedance measurements between different combinations of the reference electrodes and the ablation electrodes and, based on the impedance measurements, identifying two or more electrode groups for treatment, where at least two of the electrode groups include a different one of the reference electrodes and a different one of the ablation electrodes.

摘要： Transducer-based systems can be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Selection of a plurality of graphical elements and/or between graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

摘要： An effector includes a tubular body having a proximal end and a distal end. The effector holds a plug or closure at the distal end of the tubular body; an active electrode at the distal end of the body; an insulator on the body; and one or more return electrodes on the insulator. The body dissipates heat generated by the one or more return electrodes from the distal end of the body to the proximal end of the body.

摘要： Methods and apparatus are provided for monopolar neuromodulation, e.g., via a pulsed electric field. Such monopolar neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, monopolar neuromodulation is applied to neural fibers that contribute to renal function. In some embodiments, such monopolar neuromodulation is performed bilaterally.

摘要： Methods, systems, and devices for providing treatment to a tissue in body lumens are described. The system may include a catheter, an expansion member coupled with a distal portion of the catheter, an ablation structure including one or more longitudinal electrode segments, and an ablation structure support coupled to the ablation structure configured to at least partially unfurl as the expansion member expands and furl as the expansion member contracts. The ablation structure may include multiple separately wired and/or separately controlled longitudinal electrodes, longitudinal electrode zones, or both, such that each longitudinal electrode or longitudinal electrode zone may be selectively enabled or selectively disabled. In some instances, one or more springs are coupled to the ablation structure configured to promote unfurl or furl around the expansion member. In some instances, one or more protection elements are be positioned along the catheter.
