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.

Devices, systems and methods for evaluation and feedback of neuromodulation treatment

Apparatuses, systems and methods are provided for treating pulmonary tissues via delivery of energy, generally characterized by high voltage pulses, to target tissue using a pulmonary tissue modification system (e.g., an energy delivery catheter system). Example pulmonary tissues include, without limitation, those within the respiratory tract, particularly the epithelium (the goblet cells, ciliated pseudostratified columnar epithelial cells, and basal cells), lamina propria, submucosa, submucosal glands, basement membrane, smooth muscle, cartilage, nerves, pathogens resident near or within the tissue, or a combination of any of these. The systems may be used to treat pathogens, such as bacteria and viruses, particularly coronaviruses.

Immunostimulation in the treatment of viral infection

Apparatuses, systems and methods are provided for treating pulmonary tissues via delivery of energy, generally characterized by high voltage pulses, to target tissue using a pulmonary tissue modification system (e.g., an energy delivery catheter system). Example pulmonary tissues include, without cells), lamina propria, submucosa, submucosal glands, basement membrane, smooth muscle, cartilage, nerves, pathogens resident near or within the tissue, or a combination of any of these. The system may be used to treat a variety of pulmonary diseases or disorders such as or associated with COPD (e.g., chronic bronchitis, emphysema), asthma, interstitial pulmonary fibrosis, cystic fibrosis, bronchiectasis, primary ciliary dyskinesia (PCD), acute bronchitis and/or other pulmonary diseases or disorders.

Methods, apparatuses, and systems for the treatment of pulmonary disorders

Energy is transmitted to a body lumen or passageway in the form of pulsed electric fields (PEFs) and in a manner which provides focal therapy. In some embodiments, PEFs are delivered through independent electrically active electrodes of an energy delivery body, typically in a monopolar fashion. Such delivery concentrates the electrical energy over a smaller surface area, resulting in stronger effects than delivery through an electrode extending circumferentially around the lumen or passageway. It also forces the electrical energy to be delivered in a staged regional approach, mitigating the effect of preferential current pathways through the surrounding tissue. Focal delivery of PEFs can provide increased tissue lethality by employing precise timing and sequencing of energy delivery to the electrodes.

Optimization of energy delivery for various applications

Embodiments described herein relate to signal generators, systems including signal generators, and related methods. A signal generator includes capacitor(s) to store energy used to generate a treatment signal. The signal generator also includes a waveform shaping circuit, a controller, a voltage sense circuit, and a current sense circuit. The waveform shaping circuit is coupled to the capacitor(s) and includes first, second, third, and fourth switches, each of which is configured to be selectively turned ON and OFF, to allow current to pass through the switch when turned ON, and to prevent current from passing through the switch when turned OFF. The controller selectively controls the switches in order to generate the treatment signal. The controller also selectively controls the switches in order to perform certain fault tests, which rely on voltages sensed by the voltage sense circuit and currents sensed by the current sense circuit.
