  • Patent number: 11439460
    Abstract: The present disclosure provides catheter systems, electrode assemblies, and methods for electrically stimulating one or more points about the circumference of the renal artery to provide real time intraprocedural operational feedback to the operator of a renal denervation procedure to allow for more precise and thorough ablation of the renal artery and better patient outcomes. In many embodiments, an electrode assembly is provided that includes multiple splines that extend from an insulated proximal hub to an insulated distal hub and are interconnected to an electrical wire to allow the splines to independently function as electrical stimulation electrodes. The electrically active splines can then be energized at one or more desired points during a renal denervation procedure to provide operational feedback.

  • Publication number: 20210267670
    Abstract: An ablation catheter comprises an elongated catheter body; at least one ablation element disposed in a distal portion which is adjacent the distal end of the catheter body; an illumination optical element disposed in the distal portion, the illumination optical element being light-transmissive to emit light from the illumination optical element to the targeted tissue region; and a collection optical element disposed in the distal portion, the collection optical element being light-transmissive to collect one or more of returned, backscattered or newly excited light from the targeted tissue region. The illumination or excitation optical element and the collection optical element are axially spaced from one another and axially optically isolated from one another within the distal portion to substantially prevent light from traveling between the illumination optical element and the collection optical element along a path within the distal portion.
