An apparatus for maneuvering a medical device, the apparatus comprising: a support member extending along a longitudinal axis; a flexible elongate member having a distal portion and a proximal portion, wherein the proximal portion is operably coupled to the support member; a first adjusting knob and a second adjusting knob (234, 236), the first and second adjusting knobs (234, 236) rotatably coupled to the support member, with the first and second adjusting knobs (234, 236) being rotatable about the longitudinal axis; a first pair of deflection wires (240a, 240b) operably coupled to the first adjusting knob and to the distal portion of the flexible elongate member; and a second pair of deflection wires (240c, 240d) operably coupled to the second adjusting knob and to the distal portion of the flexible elongate member; wherein rotation of the first adjusting knob imparts a tensile force on one of the first pair of deflection wires (240a, 240b) thereby causing the distal portion of the flexible elongate member to deflect in a first direction, wherein rotation of the second adjusting knob imparts a tensile force on one of the second pair of deflection wires (240c, 240d) thereby causing the distal portion of the flexible elongate member to deflect in a second direction, further comprising a first slide member and a second slide member, wherein the first slide member comprises a first pair of slide members (270, 272) and the second slide member comprises a second pair of slide members (320, 322), said first and second pairs of slide members (270, 272; 320, 322) being displaceable along a portion of a length of the support member, wherein the first pair of slide members (270, 272) is operably coupled to the first adjusting knob and to the first pair of deflection wires (240a, 240b), wherein the second pair of slide members (320, 322) is operably coupled to the second adjusting knob and to the second pair of deflection wires (240c, 240d), characterized in that the first pair of slide members (270, 272) is positioned within the support member and the second pair of slide members (320, 322) is positioned against an outside of the support member. a support member extending along a longitudinal axis; a flexible elongate member having a distal portion and a proximal portion, wherein the proximal portion is operably coupled to the support member; a first adjusting knob and a second adjusting knob (234, 236), the first and second adjusting knobs (234, 236) rotatably coupled to the support member, with the first and second adjusting knobs (234, 236) being rotatable about the longitudinal axis; a first pair of deflection wires (240a, 240b) operably coupled to the first adjusting knob and to the distal portion of the flexible elongate member; and a second pair of deflection wires (240c, 240d) operably coupled to the second adjusting knob and to the distal portion of the flexible elongate member; wherein rotation of the first adjusting knob imparts a tensile force on one of the first pair of deflection wires (240a, 240b) thereby causing the distal portion of the flexible elongate member to deflect in a first direction, wherein rotation of the second adjusting knob imparts a tensile force on one of the second pair of deflection wires (240c, 240d) thereby causing the distal portion of the flexible elongate member to deflect in a second direction, further comprising a first slide member and a second slide member, wherein the first slide member comprises a first pair of slide members (270, 272) and the second slide member comprises a second pair of slide members (320, 322), said first and second pairs of slide members (270, 272; 320, 322) being displaceable along a portion of a length of the support member, wherein the first pair of slide members (270, 272) is operably coupled to the first adjusting knob and to the first pair of deflection wires (240a, 240b), wherein the second pair of slide members (320, 322) is operably coupled to the second adjusting knob and to the second pair of deflection wires (240c, 240d), characterized in that the first pair of slide members (270, 272) is positioned within the support member and the second pair of slide members (320, 322) is positioned against an outside of the support member.
