Abstract

A steerable stylet and manipulative handle assembly for guiding a lead or a catheter to a desired location in a patient. The steerable stylet comprises an outer, elongated tubular member of a length sufficient to extend through the length of the lead or catheter from its proximal opening to the distal end thereof, a traction element or pull wire extending generally through the length of the tubular member and within its lumen except for a span in the distal portion thereof, and a manipulative handle coupled to the proximal ends of the tubular member and wire. Traction applied with one hand to the pull wire via the handle causes the distal portion of the tubular member to bend. Distal portion of the tubular member is provided with openings to allow the wire to exit and re-enter the lumen and facilitate bending of the tubular member. Distal portion of the tubular member which bends is preferably deformed, such as cut out or flattened or indented, to avoid kinking. A retainer surrounds the area proximate the openings and protects the exposed pull wire.
