    Abstract: The present disclosure provides to process intravascular ultrasound (IVUS) images from different runs through a vessel to generate a mapping between frames of each IVUS run and to generate a graphical user interface (GUI) to graphically present the IVUS runs in relationship to each other. In some examples, a vessel fiducial is identified in a frame of each IVUS run and one or both runs are offset in time, distance, and/or angle to align the frames with the identified vessel fiducial. Further, the disclosure provides to angularly align intravascular images to a viewing perspective of an external image of the vessel.

    Abstract: A device for treating hemorrhoids includes a first ligating member which moves between a first position in which the first member is tightened to a degree required to maintain a desired position of the first member around the first portion without significantly cutting off blood flow and a second configuration in which the first member is cinched down around the first portion to substantially cut off blood flow to the encircled first portion. Also, the device includes a first applicator having a proximal lumen and first and second opposed distal lumens open to the proximal lumen. The first member is extending from a proximal end distally through the proximal lumen into the first lumen to exit a distal end of the first lumen, loop around and enter the distal end of the second lumen. The first member is passing through the second lumen into the proximal lumen.

    Abstract: Catheter systems, tools and methods are disclosed for the selective and rapid application of DC voltage to drive irreversible electroporation, with the system controller configurable to apply voltages to an independently selected subsets of electrodes, such that voltages of one polarity are applied to a multiplicity of electrodes on a first medical device and voltages of the opposite polarity to a multiplicity of electrodes on a second medical device. The first and second medical devices can be epicardial catheters positioned such that their opposing distal tips are approximately aligned and whose segments with electrodes collectively wrap around the pulmonary veins.

    Abstract: A method of providing embolic protection for carotid stenting includes advancing an arterial sheath into a patient's arterial system and advancing a venous sheath into the patient's venous system. A fluid connection may be established between the venous sheath and the arterial sheath that enables retrograde blood flow through the arterial sheath. The arterial sheath may be advanced through the vasculature and into the patient's carotid artery, and an inflatable balloon may be inflated within the patient's carotid artery in order to occlude antegrade blood flow therethrough. An interventional tool may be advanced through the inner lumen of the arterial sheath, the interventional tool dimensioned such that a portion of the cross-sectional area of an inner lumen of the arterial sheath remains open for retrograde blood flow.
