  • Publication number: 20240065757
    Abstract: 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.

  • Patent number: 11883087
    Abstract: Methods for treating a patient using therapeutic renal neuromodulation and associated devices, systems, and methods are disclosed herein. One aspect of the present technology is directed to methods including selectively neuromodulating afferent or efferent renal nerves. One or more measurable physiological parameters corresponding to systemic sympathetic overactivity or hyperactivity in the patient can thereby be reduced. Selectively neuromodulating afferent renal nerves can include inhibiting sympathetic neural activity in nerves proximate a renal pelvis. This can include, for example, neuromodulating via fluid within the renal pelvis. Selectively neuromodulating efferent renal nerves can include inhibiting sympathetic neural activity in nerves proximate a portion of a renal artery or a renal branch artery proximate a renal parenchyma. This can include, for example, neuromodulating via a therapeutic element within the portion of the renal artery or the renal branch artery.

  • Publication number: 20220409059
    Abstract: Systems and methods for informing and evaluating neuromodulation therapy are disclosed herein. A system configured in accordance with embodiments of the present technology can include, for example, a guidewire having a proximal portion, a distal portion configured to be positioned at a target site in a blood vessel of a human patient, and a sensing element positioned along the distal portion. The sensing element can be a pressure sensing element, a flow sensing element, an impedance sensing element, and/or a temperature sensing element. The system can further include a controller configured to obtain one or more measurements related to a physiological parameter of the patient via the sensing element. Based on the measurements, the controller can determine the physiological parameter and compare the parameter to a predetermined threshold. Based on the comparison, the controller and/or the operator can assess the likelihood of the patient benefitting from neuromodulation therapy.

  • Publication number: 20220241020
    Abstract: Methods and systems for optimizing perivascular neuromodulation therapy using computational fluid dynamics. Digital data regarding three-dimensional imaging of a target blood vessel and corresponding hemodynamic data are inputs to generating a computational fluid dynamics (CFD) model. The CFD model enables identification of one or more regions of the vessel suitable for neuromodulation therapy and/or identifying one or more regions of the vessel to avoid during such therapy. A system of the present technology can include a neuromodulation catheter, a computing device that can generate and analyze the CFD model, and a user interface for displaying the vessel with indicia for target regions and/or avoidance regions.
