Patent ID: 8376991

Claim:
A medical device, comprising: an elongate core having a proximal end portion and a deflectable distal end portion; a strut disposed at said distal end portion configured to reduce axial shortening of said deflectable distal end portion of said elongate core due to repeated deflection that would result in a state where said deflectable distal end is compressed relative to an original axial length, said strut having a central through-bore extending longitudinally therethrough; a steering ring coupled on a distal side of said strut; and a plurality of steering wires coupled to said steering ring and extending to said proximal end portion of said core, said steering wires being disposed radially outwardly of said strut and completely outside of said bore; a coil coupled on a proximal side of said strut and outwardly of said core and a wire mesh defined by a plurality of braided flat wires, said wire mesh surrounding said steering wires.
