Abstract: In one example, a system includes a deployment catheter defining at least one lumen therethrough. The system further includes a balloon member projecting distally from a distal end of the deployment catheter and defining an area therein, wherein the area is in fluid communication with the at least one lumen. The system further includes a first opening at the distal end of the balloon member, a first instrument lumen extending through the balloon member from the distal end of the deployment catheter to the first opening, and a visualization element disposed within the balloon member for visualizing tissue external to the balloon member.

Abstract: A medical manipulation assembly comprises a catheter including distal and proximal steerable portions with working channels. The assembly further comprises a steerable sheath through which the steerable portions extend. A distal steering mechanism, including a first lumen extending along a longitudinal axis of the catheter, bends the distal steerable portion. A proximal steering mechanism, including a second lumen extending along the axis and defined by a wall, bends the proximal steerable portion by rotational movement of the proximal steering mechanism independently of the distal steerable portion. The wall is rotatable about the axis. Distal pullwires extend between the distal steerable portion and the distal steering mechanism. Proximal pullwires extend between the proximal steerable portion and the proximal steering mechanism. The second lumen is axially aligned with an access lumen extending proximally from the proximal steering mechanism through which the distal and proximal working channels may receive a visualization instrument.

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: A method of cannulating a coronary sinus within a heart chamber includes deploying, from a catheter, an imaging hood to a deployed configuration by extending the imaging hood from a distal end of the catheter and radially expanding the imaging hood to define a constant deployed volume within an open area of the imaging hood. The method further includes positioning a contact edge of the imaging hood and the open area of the imaging hood in the deployed configuration over or upon an ostium of the coronary sinus, displacing an opaque fluid with a transparent fluid from the open area defined by the imaging hood and tissue surrounding the ostium, visualizing the ostium through the transparent fluid by viewing the ostium via an imaging element attached to an inner surface of the imaging hood, and introducing a guidewire through the imaging hood and into the ostium while under visual guidance.

Abstract: A method of inhibiting flow of a purging fluid from a device comprises positioning an imaging hood in proximity to a tissue region to be visualized. The imaging hood includes a distal membrane which defines a main aperture. The imaging hood and the distal membrane define an open area. The method also comprises introducing the purging fluid into a proximal portion of the open area. The proximal portion is bounded by a proximal membrane including a plurality of apertures. The method also comprises pressurizing the proximal membrane with the purging fluid to a partially extended state in which the purging fluid flows through the plurality of apertures and through the main aperture. The method also comprises pressurizing the proximal membrane with the purging fluid to a blocking extended state in which the proximal membrane obstructs the main aperture to block the flow of the purging fluid through the main aperture.

Abstract: A method of inhibiting a flow of a purging fluid from a tissue visualization device comprises positioning an imaging hood attached to a distal end of a flexible elongate shaft in proximity to a tissue region to be visualized The method also comprises introducing the purging fluid into an inflation member suspended within an open area of the imaging hood. The inflation member includes at least one aperture on a proximal portion of the inflation member. The method also comprises inflating the inflation member to a partially inflated state in which the inflation member is circumferentially separated from an inner surface of the hood to form an annular flow path for the purging fluid from the at least one aperture, between the inner surface of the hood and the inflation member, and into fluid communication with an environment external to the hood. The method also comprising inflating the inflation member to a blocking inflated state in which the inflation member expands into contact with the imaging hood to block the flow from the at least one aperture to the annular flow path.
