Claim Text:
1. An elongate medical device comprising: a shaft body comprising a distal end portion and a proximal end portion, wherein said shaft body has an axis from said proximal end portion to said distal end portion; and three deflection wire assemblies, each deflection wire assembly coupled to said distal end portion of said shaft body and configured to be deflected such that said distal end portion of said shaft body is deflected in substantially the same direction relative to said axis as the deflection of each deflection wire assembly, wherein each deflection wire assembly comprises a flat wire, each flat wire having a distal end, wherein said distal ends of said flat wires are coupled to a common location of said distal end portion of said shaft body, further wherein each flat wire has a respective length that is different from each other flat wire, wherein the respective length of each flat wire defines a respective radius of deflection of the distal end portion of said shaft body, wherein each respective radius of deflection is different.
