Bi-directional steerable catheter control handle
First Claim
1. A handle for controlling distal end deflection of a catheter body, wherein the catheter body includes first and second deflection wires, the handle comprising:
- a slide base including a first end, a second end, and a slide compartment longitudinally extending through at least a portion of the slide base;
an adjustment knob rotateably connected to the first end of the slide base and including a hole extending through the knob, wherein at least a portion of an inner diameter of the hole includes an internal right thread and an internal left thread;
a first slide located in the slide compartment, adapted to be coupled to the first deflection wire and including an external right thread; and
a second slide located in the slide compartment, adapted to be coupled to the second deflection wire and including an external left thread, wherein the internal threads of the knob engage the threads of the slides and rotation of the adjustment knob causes the slides to displace in opposite directions within the slide compartment.

Abstract
The present invention is a handle for controlling the deflection of a distal end of a catheter body. The catheter body includes first and second deflection wires that extend through the catheter body from the distal end of the catheter body. The handle comprises a slide base, an adjustment knob, a first slide and a second slide. The slide base includes a first end, a second end, and a slide compartment longitudinally extending through at least a portion of the slide base. The adjustment knob is rotateably connected to the first end of the slide base and includes a hole extending through the knob, wherein at least a portion of an inner diameter of the hole includes an internal right thread and an internal left thread. The first slide is located in the slide compartment, is adapted to be coupled to the first deflection wire, and includes an external right thread. The second slide is located in the slide compartment, is adapted to be coupled to the second deflection wire, and includes an external left thread. The internal threads of the knob engage the threads of the slides. Consequently, in operation, rotation of the adjustment knob causes the slides to displace in opposite directions within the slide compartment and the distal end of the catheter body to deflect accordingly.

15. A handle for controlling distal end deflection of a catheter body, wherein the catheter body includes a first deflection wire and a second deflection wire, the handle comprising:
-
a first handle portion rotateably coupled to a second handle portion; and
a first member and a second member longitudinally displaceable within the handle, wherein the first member is adapted to couple to the first deflection wire, the second member is adapted to couple to the second deflection wire, and rotation of the first handle portion relative to the second handle portion causes the members to displace in opposite directions. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A method of deflecting a distal end of a catheter body, wherein the catheter body includes first and second deflection wires, the method comprising:
-
coupling a first member to the first deflection wire, wherein the first member includes a right thread;
coupling a second member to the second deflection wire, wherein the second member includes a left thread;
rotateably coupling a first handle portion to a second handle portion, wherein the first handle portion includes a right thread and a left thread and said threads are engaged with the threads of the first and second members; and
rotating the first handle portion relative to a second handle portion such that the first and second members are caused to displace in opposite directions, thereby deflecting the distal end of the catheter body. - View Dependent Claims (48, 49, 50)

51. A surgical method comprising:
-
providing a catheter including a catheter body and a handle attached to a proximal end of the catheter body, the handle including an adjustment knob rotateably coupled to a base;
inserting a distal end of the catheter body into a body of a patient;
advancing the distal end of the catheter body until positioned in a selected location within the body of the patient; and
deflecting the distal end of the catheter body by rotating the adjustment knob about a longitudinal axis of a base, thereby oppositely displacing a pair of members in the handle along the longitudinal axis, wherein each member is coupled to a deflection wire running though the catheter body and coupled to the distal end.
