Abstract

A method comprises steering a deployment catheter to locate a distal end of the deployment catheter at a position within a patient anatomy. The method further includes articulating a delivery catheter extending through and from the distal end of the deployment catheter while the distal end of the deployment remains at the position and deploying an instrument through the delivery catheter.

Claims

1. A method comprising:

steering a deployment catheter to locate a distal end of the deployment catheter at a position within a patient anatomy;

articulating a delivery catheter extending through and from the distal end of the deployment catheter while the distal end of the deployment catheter remains at the position;

deploying an instrument through the delivery catheter; and

articulating a sheath through which the deployment catheter extends, wherein articulation of the sheath is separate from the steering of the deployment catheter.

2. The method of claim 1 wherein the delivery catheter includes an optical imaging assembly.

3. The method of claim 1 further comprising:

extending a tissue piercing device from the delivery catheter.

4. The method of claim 1 wherein the deployment catheter is steered under computer control.

5. The method of claim 1 further comprising:

conducting a first procedure with the instrument while the distal end of the delivery catheter is articulated in a first direction and the distal end of the deployment catheter is at the position within the patient anatomy; and

conducting a second procedure with the instrument while the distal end of the delivery catheter is articulated in a second direction and the distal end of the deployment catheter is at the position within the patient anatomy.

6. The method of claim 1 further comprising:

capturing a first image while the distal end of the delivery catheter is articulated in a first direction and the distal end of the deployment catheter is at the position within the patient anatomy; and

capturing a second image while the distal end of the delivery catheter is articulated in a second direction and the distal end of the deployment catheter is at the position within the patient anatomy.

7. The method of claim 1 further comprising:

translating the deployment catheter independently of the sheath.

8. The method of claim 1 wherein articulating the sheath includes manipulating at least one wire extending within the sheath.

9. The method of claim 1 further comprising delivering a fluid through a fluid delivery lumen of the delivery catheter.

10. The method of claim 1 wherein steering the deployment catheter includes manipulating at least one wire extending within the deployment catheter.

11. The method of claim 1 wherein articulating the delivery catheter includes manipulating at least one wire extending within the delivery catheter.

12. The method of claim 1 wherein the instrument is an ablation probe.

13. The method of claim 1 further comprising stabilizing the deployment catheter at the position within the patient anatomy.

14. The method of claim 1 wherein the delivery catheter includes an optical fiber.

15. A method comprising:

steering a deployment catheter to locate a distal end of the deployment catheter at a position within a patient anatomy;

articulating a delivery catheter extending through and from the distal end of the deployment catheter while the distal end of the deployment catheter remains at the position;

deploying an instrument through the delivery catheter;

conducting a first procedure with the instrument while the distal end of the delivery catheter is articulated in a first direction and the distal end of the deployment catheter is at the position within the patient anatomy; and

conducting a second procedure with the instrument while the distal end of the delivery catheter is articulated in a second direction and the distal end of the deployment catheter is at the position within the patient anatomy.

16. A method comprising:

steering a deployment catheter to locate a distal end of the deployment catheter at a position within a patient anatomy;

articulating a delivery catheter extending through and from the distal end of the deployment catheter while the distal end of the deployment catheter remains at the position;

deploying an instrument through the delivery catheter;

capturing a first image while the distal end of the delivery catheter is articulated in a first direction and the distal end of the deployment catheter is at the position within the patient anatomy; and

capturing a second image while the distal end of the delivery catheter is articulated in a second direction and the distal end of the deployment catheter is at the position within the patient anatomy.
