    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: 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 tissue manipulation system comprises a reconfigurable hood structure with a distal end. The structure has a low profile delivery configuration and an expanded deployed configuration which defines an open area bounded at least in part by the structure and by an interface surface extending across the hood structure distal end. The open area is in fluid communication with an environment external to the hood structure. The system also includes a catheter in communication with the open area such that introduction of a fluid through the catheter purges the open area of bodily fluid. The interface surface is slanted relative to the catheter longitudinal axis when the hood structure is in the expanded deployed configuration. The system also includes an imaging element positioned on the hood structure such that the open area is visualized through the fluid by the element.

    Abstract: A tissue manipulation system comprises a reconfigurable hood structure with a distal end. The hood structure has a membrane extending across the hood structure distal end. The membrane includes an aperture with an aperture diameter smaller than an outer lip diameter of the hood structure in the expanded deployed configuration. The system also includes a fluid lumen in communication with the open area and an inflatable balloon member translatable through the aperture in the membrane and distal to the open area. The system also comprises an expandable stent positioned upon the balloon member. The stent has an unexpanded configuration sized to pass through the aperture in the membrane.

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. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for treating the tissue region of interest.
