Dual-deflecting electrophysiology catheter

An electrophysiology catheter comprising:

• a tubular catheter body having a proximal region, a neck region, and a distal region predisposed into at least a partial loop disposed in a plane;
• at least one electrode disposed on the distal region;
• a first deflection assembly operable to deflect the proximal region of the tubular catheter body such that the at least a partial loop of the distal region deflects from the plane;
• a second deflection assembly operable to deflect the neck region of the tubular catheter body such that the at least a partial loop of the distal region deflects from the plane;
• and
• a handle joined to the proximal region, the handle comprising:
• a first actuator operably coupled to the first deflection assembly;
• and
• a second actuator operably coupled to the second deflection assembly.

An electrophysiology catheter comprising:

• a tubular catheter body having a proximal region, a neck region, and a distal region predisposed into at least a partial loop disposed in a plane;
• at least one electrically-active region disposed on the distal region;
• a handle joined to the proximal region, the handle comprising a first actuator and a second actuator;
• a first deflection mechanism comprising a first deflection wire operably coupled to the first actuator such that actuation of the first actuator causes deflection in the proximal region that causes the at least a partial loop of the distal region to deflect from the plane;
• and
• a second deflection mechanism comprising a second deflection wire operably coupled to the second actuator such that actuation of the second actuator causes deflection in the neck region that causes the at least a partial loop of the distal region to deflect from the plane.
