Abstract: A manipulation assembly comprises: a delivery catheter having a lumen extending therethrough; and a deployment catheter positioned within the lumen of the delivery catheter. The delivery catheter is manipulatable within multiple planes. The deployment catheter is independently manipulatable with respect to the delivery catheter and includes a first lumen and a second lumen. The assembly further comprises an elongate, flexible visualization element positioned within the first lumen of the deployment catheter and extendable distally beyond the delivery catheter. The visualization element is articulatable with respect to the delivery catheter. The assembly further comprises an ablation probe positioned within the second lumen of the deployment catheter and comprises an illumination tool routed through the deployment catheter. The ablation probe is extendable distally beyond the deployment catheter and is positionable off-axis with respect to a longitudinal axis of the delivery catheter. The illumination tool is manipulatable with respect to the delivery catheter.

Abstract: A medical manipulation assembly includes a catheter and distal and proximal steering mechanisms. The catheter includes distal and proximal steerable portions with working channels configured to receive an instrument. The distal steering mechanism is operable to bend the distal steerable portion in a first plane relative to the proximal steerable portion in response to movement of a first portion of the distal steering mechanism about a first axis of rotation and to bend the distal steerable portion in a second plane relative to the proximal steerable portion in response to movement of a second portion of the distal steering mechanism about a second axis of rotation. The proximal steering mechanism is operable to bend the proximal steerable portion by rotational movement of the proximal steering mechanism. Distal pullwires extend between the distal steerable portion and steering mechanism and proximal pullwires extend between the proximal steerable portion and steering mechanism.
