Modular handle assembly for a steerable catheter
First 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.

Abstract
A modular handle assembly for supporting and controlling a steerable catheter having at least one deflection wires includes a handle extending along an axis for being secured about a portion of the steerable catheter. The modular handle assembly includes at least one barrel rotatably connected to the handle for rotation about the axis, and at least one spindle disposed in and connected with said barrel for rotation about the axis with the barrel. At least one guide cable extends from an anchored end being anchored to the spindle to a distant end for connection with one of the deflection wires of the steerable catheter. The guide cable is wrapped about the spindle for axially moving the deflection wires in response to rotation of the first spindle about the axis by the barrel to curl the distal tip of the elongated body of the steerable catheter.

8. A modular handle assembly for supporting and controlling a steerable catheter having at least a pair of deflection wires, 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 barrel for rotation about said axis with said barrel, a pair of guide cables each extending from an anchored end being anchored to said at least one spindle to a distant end for connection with one of the deflection wires of the steerable catheter, said pair of guide cables wrapped about said at least one spindle in opposite directions to one another radial to said axis to move said pair of guide cables in opposite directions from one another during rotation of said at least one spindle for moving the deflection wires and curling the distal tip of an elongated body of the steerable catheter, 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 further including a pair of arms extending axially from said base and extending to an edge, each of said arms defining a groove extending axially from said edge toward said base of said frame for receiving one of said guide cables to align said guide cables and space said guide cables from said at least one spindle, each of said arms extending from said base of said frame from diametrically opposite sides of said perimeter, said at least one spindle including a platform having a washer shape disposed about said conduit of said frame and presenting an outer periphery, and said outer periphery of said at least one spindle defining a channel that extends radially inwardly and annularly about said outer periphery of said platform. - View Dependent Claims (9, 10, 11)
