    Abstract: 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.

    Abstract: A coupler for coupling a flexible coaxial cable (32), a fluid cooling system (40) and the outer sheath (35) of a catheter (30), the coupler comprising:
    a fluid coupler body (845a) including:
    a fluid inlet (842a) configured to operably couple to a source of cooling fluid and receive fluid therefrom;
    a fluid outlet (843a) configured to operably couple to a fluid discharge; and
    an outer sheath coupler (845b) forming an aperture for coupling with an outer sheath (35) of a catheter while forming a fluid-tight seal therewith; and

    a fluid sealing system (819) housed in the fluid coupler body including:
    a distal sealing diaphragm (819a) configured to form a fluid-tight seal about an outer surface of an inflow lumen (842) and a fluid-tight seal with an interior surface of the fluid coupler body (845a) defining an outflow plenum (843b) in fluid communication with the fluid outlet (843a); and
    a proximal sealing diaphragm (819b) configured to form a fluid-tight seal about an outer surface of the coaxial cable (32) and a fluid-tight seal with an interior surface of the fluid coupler body(845a) thereby forming an inflow plenum (842b) in fluid communication with the fluid inlet (842a).

    Abstract: An energy delivery system for delivering electrical energy to tissue, includes an elongate catheter member defining a longitudinal axis and dimensioned for passage within a body vessel and an expandable treatment member mounted to the catheter member. The treatment member includes an inflatable element adapted to transition between an initial condition and an at least partially expanded condition upon introduction of an anesthetic solution within the inflatable element, an electrode for delivering electrical energy to at least the nerve tissue associated with the body vessel to cause at least partial denervation thereof and at least one aperture dimensioned to permit passage of the anesthetic solution from the inflatable element to contact the body vessel whereby the solution at least enters the body vessel to at least partially anesthetize the nerve tissue therewithin. The electrode may be mounted to at least the inflatable element of the treatment member and may be generally helical.
