    摘要: Methods and apparatus are provided for pulsed electric field neuromodulation via an intra-to-extravascular approach, e.g., to effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, changes in cytokine upregulation and other conditions in target neural fibers. In some embodiments, the ITEV PEF system comprises an intravascular catheter having one or more electrodes configured for intra-to-extravascular placement across a wall of patient's vessel into proximity with target neural fibers. With the electrode(s) passing from an intravascular position to an extravascular position prior to delivery of the PEF, a magnitude of applied voltage or energy delivered via the electrode(s) and necessary to achieve desired neuromodulation may be reduced relative to an intravascular PEF system having one or more electrodes positioned solely intravascularly. The methods and apparatus of the present invention may, for example, be used to modulate one or more target neural fibers that contribute to renal function.

    摘要: Interventional catheter-based systems and methods are described herein for use in generating an initial pathway through vascular occlusions. The catheter systems generally include two elements. A first element is a Blunt Dissection Catheter including a manually actuated assembly located at the distal tip of the Blunt Dissection Catheter that performs blunt dissection in the vascular occlusion to produce a dissection track, or small pathway through the occlusion. The second element is a Sheath Catheter that serves as a conduit within which the Blunt Dissection Catheter is freely advanced, retracted and rotated. The first and second elements are used in some combination to cross vascular occlusions in both the coronary and peripheral vasculature.
