Patent ID: 8070693

Claim:
A steerable wire guide having a longitudinal axis, comprising: a composite structure comprising a first member and a second member which are joined together by a flexible loop at the distal end of a leading portion at the distal end of the composite structure, a tubular sheath surrounding the first member and the second member, and a handle at the proximal end of the tubular sheath, connected to the first and second members, to control movement of the first and second members; wherein the first member and second member are movable relative to each other and relative to the tubular sheath such that concurrent movement of the first and second members in a first direction causes the first and second members to advance the leading portion, while the concurrent movement of the first and second members in a second direction retracts the leading portion; and such that movement of the first member relative to the second member in a first direction moves the leading portion in a third direction, and movement of the first member relative to the second member in a second direction opposite the first direction, moves the leading portion in a fourth direction, opposite the third direction, and wherein the first member is concentrically disposed around the second member.
