Abstract

A steerable probe with a deflectable tip. In one embodiment, the probe may include a cannula having a proximal end and a distal end and extending along a length therebetween, an exterior surface, an interior surface defining a lumen, an elongate flexible section extending along a first portion of the length and having a section proximal end and a section distal end. A pull wire for deflecting the flexible section in a first direction in a preferred bending plane may be substantially embedded in the cannula between the interior surface and the exterior surface and extending from the section proximal end to the section distal end. The pull wire may be secured to the cannula adjacent to the section distal end and freely passing through the section proximal end. Two longitudinal strengthening members may be embedded in and extend along the flexible section generally opposite each other about the preferred bending plane.
