    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: Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.

    Abstract: A system comprises a deployment catheter defining at least one lumen and a hood projecting distally from the deployment catheter and defining an open area. The open area is in direct fluid communication with the at least one lumen. The system also comprises an elongate channel directly coupled to the hood such that the elongate channel terminates distally into the open area. The elongate channel extends proximally from an outer surface of the hood and is bounded proximally at a proximal pocket surface. The system also comprises an imaging element. The imaging element is sized to pass into the elongated channel at a distal end of the elongate channel. Proximal movement within the elongated channel is restricted by the proximal pocket surface. The system also comprises a control member extending within the elongate channel and through the proximal pocket surface for moving the imaging element through the elongate channel.
