    Abstract: A catheter apparatus includes an elongated body having a distal portion including a distal end, a plurality of flexible segments, and at least one intermediate segment that is less flexible than the flexible segments. Adjacent flexible segments are spaced from each other longitudinally by the at least one intermediate segment. Each of the flexible segments include a sidewall having at least one elongated gap extending at least partially therethrough and forming interlocking members. The at least one intermediate segment is shorter than the flexible segments.

    Abstract: A catheter includes a flexible tubing having a proximal end and a distal end. The catheter also includes an electrode assembly attached to the distal end of the flexible tubing and having a first magnet therein. The electrode assembly further includes an electrically conductive tip electrode and an electrically nonconductive coupler which is connected between the tip electrode and the distal end of the flexible tubing. The coupler and the tip electrode are coupled by an interlocking connection. The catheter also includes a second magnet spaced from the electrode assembly along a longitudinal axis of the tubing. The first magnet and the second magnet are responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.

    Abstract: A method for denervation comprises introducing a distal portion of a catheter through an interior of a vessel of a patient to a location at or proximate one of a renal pelvis or a calyx. The catheter includes an elongated catheter body extending longitudinally between a proximal end and a distal end. The catheter body includes the distal portion at the distal end and a catheter lumen from the proximal end to the distal end. Energy is delivered from the distal portion to cause renal denervation, for example, by denervating at least some tissue proximate at least one of the renal pelvis or a renal vessel from a location at or proximate the renal pelvis or the calyx from a location at or proximate the calyx.

    Abstract: Embodiments of the present invention provide a catheter that comprises an elongated catheter body (16) and an electrode assembly (10) at the distal end of the catheter body. The electrode assembly comprises a plurality of spines (11), each of the spines having a proximal end connected to the distal end of the catheter and a distal end, the distal ends of the spines being connected at a spine tip junction (13). Each spine includes an elbow (20) having at least one discontinuity in stiffness at an intermediate position between the distal end and the proximal end thereof. The spines include a plurality of electrodes (12). The electrode assembly is collapsible to a collapsed arrangement to fit within a lumen of the elongated catheter body and expandable to an expanded arrangement with the elbows of the spines bending outwardly relative to the proximal and distal ends of the spines.
