Patent ID: 7747314

Claim:
A guidewire, comprising: a metallic core member having a proximal end and a distal end, wherein the core member is generally solid in cross-section; a metallic tubular member having a proximal end and a distal end disposed around and attached to the distal end of the core member; and a metallic coil member disposed about and attached to the distal end of the tubular member and an outer member connected to the core member proximal of the proximal end of the tubular member and disposed around the core member, tubular member and metallic coil member, wherein the tubular member has a uniform inner diameter and a uniform outer diameter and wherein the distal end of the core member where the tubular member is attached has an outer diameter that is substantially the same as the inner diameter of the tubular member and wherein the coil member has an inner diameter that is greater than the outer diameter of the tubular member, and wherein the tubular member extends distally beyond the distal end of the core member and the coil member extends distally beyond the distal end of the tubular member.
