Abstract

Elongate medical devices with an expandable structure including elongated splines and a distal hub. An elongate medical device includes a handle including a control mechanism, a catheter shaft, an expandable structure including elongated splines and a distal hub, wherein each of the elongated splines includes a shape memory material and an interactive element, wherein each of the elongated splines includes a respective spline proximal end and a spline distal end, wherein each of the spline proximal ends is connected to the catheter shaft distal end, and wherein each of the spline distal ends is connected to the distal hub, and a deflection control member connected to the distal hub, wherein the control mechanism is drivingly coupled to the distal hub via the deflection control member and operable to selectively vary a position of the distal hub relative to the catheter shaft distal end to selectively vary an amount of expansion of the expandable structure, wherein a shape of the expandable structure is produced via a combination of the shape memory material and the position of the distal hub relative to the catheter distal end.
