Abstract
A steerable guidewire for gently penetrating an occlusion within a vessel, with an elongated solid main guidewire body having selected stiffness characteristics along its length to allow the guidewire to be urged through a narrow, tortuous body lumen by application of forces at a proximal end, and an enlarged distal end portion having a diameter larger than portions of the guidewire proximal thereof including a soft polymeric element and a permanently deflected portion to enable steering of the guidewire.
