    摘要： Various embodiments of the present disclosure can include a flexible catheter tip. The flexible catheter tip can comprise an inboard understructure that defines a tip longitudinal axis, wherein the inboard understructure is formed from a first continuous element that includes a first rectangular cross-section. In some embodiments, an outboard understructure can extend along the tip longitudinal axis, wherein the outboard understructure is formed from a second continuous element that includes a second rectangular cross-section.

    摘要： 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.
