Abstract
Intravascular catheters that include a handle assembly with first and second handle actuators, where the actuators are adapted to separately control inner and outer catheter shafts in at least one of axial displacement, deflection, or rotation. The catheters may also include a medical tool secured to the outer shaft.
Claims10
A method of controlling a catheter, comprising:
- actuating a first handle actuator to cause rotation of an outer catheter shaft relative to a catheter inner shaft, the outer shaft having a proximal end secured to a handle assembly and a distal end axially secured relative to a medical tool;
- and
- actuating a second handle actuator to cause deflection of the inner catheter shaft, and thereby cause deflection of the outer catheter shaft, wherein the first handle actuator and the second handle actuator are disposed coaxially.
