Patent ID: 7300438

Claim:
An electrophysiology catheter comprising: a handle having a distal end and a proximal end, the handle including a first actuator and a second actuator; a flexible shaft having a proximal end and a distal end and a longitudinal axis that extends along a length of the shaft, the proximal end of the shaft being attached to the distal end of the handle; a tip assembly having a proximal end and a distal end, the proximal end of the tip assembly being attached to the distal end of the shaft, the proximal end of the tip assembly including a fixed bend of approximately ninety degrees relative to the longitudinal axis of the shaft, and the distal end of the tip assembly including an arcuate curve having a diameter, the arcuate curve being oriented in a plane that is approximately perpendicular to the longitudinal axis of the shaft; a first cable, attached to the first actuator and the distal end of the tip assembly, that extends through the shaft, the first cable being adapted to change the diameter of the arcuate curve in response to movement of the first actuator; a second cable, attached to the second actuator and the proximal end of the tip assembly, that extends through the shaft, the second cable being adapted to bend the proximal end of the tip assembly in a first direction that is perpendicular to the longitudinal axis of the shaft; and a third cable, attached to the second actuator and the proximal end of the tip assembly, that extends through the shaft, the third cable being adapted to bend the proximal end of the tip assembly in a second direction that is perpendicular to the longitudinal axis of the shaft.
