Abstract: Various embodiments of the systems, methods and devices are provided for breaking up calcified lesions in an anatomical conduit wherein exemplary systems generate an electrical arc between two spaced-apart electrodes disposed within a fluid-filled balloon.

Abstract: Various embodiments of the systems, methods, and devices are provided for controlled operation of IVL for breaking up calcified lesions in an anatomical conduit. More specifically, control arrangements are disclosed concerning managing and/or providing electrical energy to generate an electrical arc between a set of spaced-apart electrodes disposed within a fluid-filled balloon, creating a determined pressure output over several voltage pulses.

Abstract: A catheter and segmented balloon system for an intravascular lithotripsy system having improved accommodation for curved configurations to prevent damage to the balloon during electrical arcing of electrode pairs. The catheter can include an elongate member with alternating flexibility regions wherein stiffer regions are configured to support at least one spaced-apart electrode pair, and wherein more flexible regions are disposed on either side of each stiffer region. This configuration allows the elongate member to curve more easily in the region of the electrodes, which are located within a balloon, or segmented balloon system. The balloon can include balloon segments with interposed sections between each of the segmented balloons wherein the outer diameter of an inflated balloon segment is larger than the outer diameter of the interposed section.

Abstract: A catheter cutting device can include a base, first and second support blocks coupled to the base, first and second roller shafts extending between and movably coupled to the first and second support blocks, and a sliding plate movably engaged with at least one of the support blocks or roller shafts such that movement of the sliding plate causes one or both of the first and second roller shafts to rotate. An arm including a cutting blade can extend in a direction perpendicular to the extension of the first and second roller shafts and can be coupled to the base or the sliding plate.
