  • Patent number: 11944373
    Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system may also include a means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The catheter may also include structures which provide radial and/or lateral support to the guide tubes so that the guide tubes expand uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

  • Publication number: 20230001189
    Abstract: An adaptive control method for controlling EP pulse parameters during electroporation (EP) of cells or tissue using an EP system includes providing a system for adaptive control to optimize EP pulse parameters including EP pulse parameters, applying voltage and current excitation signals to the cells, obtaining data from the current and voltage measurements, and processing the data to separate the desirable data from the undesirable data, extracting relevant features from the desirable data, applying at least a portion of the relevant features to a trained diagnostic model, estimating EP pulsing parameters based on an outcome of the applied relevant features, where the initialized EP pulsing parameters are based on the trained model and the relevant features, to optimize the EP pulsing parameters, and applying, by the generator, a first EP pulse based on the first pulsing parameters.

  • Patent number: 11241183
    Abstract: This document discloses EEG headset designs that address shortcomings in prior art headsets and also provides headset solutions for new and useful applications utilizing EEG headsets. One such application is brain computer interface (BCI) applications, and more specifically, a BCI application for stroke therapy in which the headset is utilized to obtain ipsilateral brain signals. This document also discloses BCI devices and methods utilizing EEG headsets.

  • Patent number: 10123800
    Abstract: Apparatus for closing a surgical incision comprise a base having left and right panels, a force distribution structure coupled to each panel, and a closure component which releasably attaches to the force distribution structure to draw the inner edges of the panels together in order to close adhered tissue edges. The force distribution structures allow the inner edges of the panels to expand while restraining expansion of the outer edges of the panels and limiting elongation of the lateral dimension of the panels. The incision closure appliance may be placed on skin or other tissue prior to forming the incision to be available to close said incision at the end of the surgical procedure.
