1. A steerable deflector, comprising:
a stylet configured with at least one groove, where the groove is a missing section disposed across only a part of a cross-section of the stylet; and, a pull wire located on the outside of the stylet and configured to cause bending of the stylet at the at least one groove, said pull wire being attached together on the exterior of the stylet and extending distally of the groove by at least one of laser welding and an over-layer positioned around the deflector where the over-layer holds the pull wire in close proximity to the stylet when the pull wire is pulled to cause bending.
