Abstract
A steerable catheter including a helical coil of wire having a longitudinal axis, a distal end, a proximal end, and a lumen extending longitudinally from the distal end to the proximal end, a ribbon having a distal end, and extending longitudinally, adjacent to the longitudinal axis, within the lumen, from the distal end of the helical coil to the proximal end of the helical coil, and a tip formed by a laser-welded fusion of the distal end of the helical coil and the distal end of the ribbon, the tip being arranged to close the distal end of the helical coil, and operatively arranged to move in a first direction away from the longitudinal axis when the ribbon is forced in a first longitudinal direction, and move in a second direction away from the longitudinal axis when the ribbon is forced in a second longitudinal direction.
