Claim:
1. A modular handle assembly for supporting and controlling a steerable catheter having at least one deflection wire, said modular handle assembly comprising; a handle extending along an axis for being secured about a portion of the steerable catheter, at least one barrel rotatably connected to said handle for rotation about said axis, at least one spindle disposed in and connected with said at least one barrel for rotation about said axis with said at least one barrel, a frame including a base disposed about said axis and presenting a perimeter connected to said handle and a conduit extending from said base along said axis, said at least one spindle being rotatably disposed about said conduit of said frame, said frame including at least one arm extending axially from said base and extending to an edge which defines a groove, at least one guide cable extending from an anchored end being anchored to said at least one spindle and bending around said groove at approximately a 90 degree angle to overlay said at least one arm between said groove and said base for aligning and spacing said at least one guide cable from said at least one spindle, said at least one guide wire further extending from adjacent said base of said frame to a distant end for connection with the at least one of deflection wire of the steerable catheter, said at least one guide cable wrapped about said at least one spindle for axially moving the deflection wire in response to rotation of said at least one spindle about said axis by said barrel to curl the distal tip of an elongated body of the steerable catheter.
