    Abstract: A catheter includes a flexible shaft having a distal end dimensioned for deployment within a patient's renal artery. A number of elongated resilient members are mounted along a longitudinal length of the distal end of the shaft, and are extensible radially from the shaft at regions defined between longitudinally spaced-apart engagement locations. One or more electrodes are mounted on each of the resilient members at the radially extensible regions. A number of conductors are electrically coupled to the electrodes and extend along the shaft of the catheter. The elongated resilient members are collapsible when encompassed within a lumen of an outer sheath and extensible radially outward from the shaft at the regions defined between the longitudinally spaced-apart engagement locations when the catheter and the resilient members are axially extended beyond the distal tip of the sheath. RF energy is delivered to the electrodes for ablating perivascular renal nerves.

    Abstract: The present disclosure, in its various aspects, is directed generally to medical devices, and more specifically to catheter accessory devices and related systems and methods. In an embodiment, an instrument accessory device may include a body with an instrument lumen through which an instrument may extend through. An expandable member may be disposed about the distal end of the body. An elongate delivery member may be attached to the body and in communication with the expandable member at a distal end of the delivery member. The delivery member may be configured to slide the instrument lumen of the body and the expandable member along the length of the instrument when extended therethrough. Other embodiments are addressed within.
