Abstract: Complex steerable catheter visualization and tissue manipulation systems and their methods of use are disclosed herein. The deployment catheter is articulated using various steering mechanisms. Tissue visualization is accomplished from the visualization hood at the distal end of the deployment catheter, the hood having an ability to expand and other features to facilitate visualization and articulation at the tissue surface.

Abstract: Flow reduction hood systems are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms.

Abstract: Systems and methods for unobstructed visualization and ablation, particularly of the pulmonary veins, are described herein. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration as well as one or more expandable anchors which are temporarily securable within a respective pulmonary vein while allowing blood flow to pass through the anchor unimpeded. With the one or more non-impeding anchors secured within a respective pulmonary vein, ablation of the tissue surrounding the ostium or several ostia may be effected with the catheter while the tissue is under direct visualization.

Abstract: A system for visualizing a tissue region of interest includes an imaging element, a sheath, and a dilator. The imaging element is configured to visualize tissue. The sheath includes a channel configured to receive the imaging element. The imaging element is positionable along a central longitudinal axis of the sheath and positionable in an off-axis position relative to the central longitudinal axis. The sheath comprises a flexible section defining at least a portion of the channel. The dilator is configured to advance through the channel to force the imaging element into the off-axis position. The dilator is configured to cause the imaging element to bulge the flexible section as the dilator is advanced through the channel.

Abstract: An apparatus for inhibiting tissue migration during a procedure comprises a deployment catheter defining at least one lumen therethrough and a non-inflatable hood projecting distally from the deployment catheter and defining an open area. The open area is in fluid communication with the at least one lumen. The apparatus also comprises a visualization element disposed within or along the non-inflatable hood for visualizing tissue adjacent to the open area. The apparatus also comprises a tissue grasping end effector positioned within the open area and configured to temporarily engage the tissue adjacent to the open area such that distal migration of the tissue relative to the barrier or membrane is inhibited.
