Abstract: A method of imaging a tissue region may comprise visualizing one or more lesions in vivo over a tissue region within a body through an imaging catheter. The method may further comprise measuring a temperature or an electrical potential of the one or more lesions. The method may further comprise overlaying a gradient indicative of the temperature or the electrical potential upon a visual image of the one or more lesions captured in vivo. The method may further comprise registering ablation parameters to the visual image of the one or more lesions and displaying the visual image with the overlaid gradient and the registered ablation parameters.

Abstract: A method of imaging a tissue region may comprise visualizing lesions over a tissue region via an imaging catheter by viewing the tissue region through a viewing region purged by a fluid and identifying, with a computer, a location of each of the lesions relative to one another over the tissue region. The method may also include registering, with the computer, a unique set of ablation parameters received from a treatment device for lesion generation for each of the lesions and generating, with the computer, a map of the lesions based on the identified locations of the lesions. The method may also include visually displaying the map of the lesions in a common display with a real-time field of view image of a first lesion; and visually displaying the registered unique set of ablation parameters for the first lesion with the real-time field of view image of the first lesion.

Abstract: A system for visualizing a tissue region of interest comprises a deployment catheter defining a lumen and a hood coupled to and extending distally from the deployment catheter. The hood has a low-profile configuration within a delivery sheath and a deployed configuration when extended distally of the delivery sheath. The hood in the deployed configuration defines an open area in fluid communication with the lumen. A distal portion of the deployment catheter extends into the open area. The system also comprises an imaging element coupled to an imager support member. When the hood is in the deployed configuration, the imaging element is configured to extend distally of the distal portion of the deployment catheter while the imager support member extends within the deployment catheter.

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.

Abstract: A method of visually locating a vessel within a body lumen comprises displacing an opaque fluid with an inflatable member contained within an open area of a barrier or membrane. The method also comprises positioning the inflatable member against or adjacent to a tissue region at a first location and visually assessing the tissue region at the first location through the inflatable member. The method also comprises repositioning the inflatable member against or adjacent to the tissue region at a second location.

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: Stent delivery under direct visualization utilizing an imaging hood is described herein. A stent may be delivered and placed in or around lesions, e.g., ostial lesions, through a delivery catheter while being directly visualized via an imaging hood. A pre-delivery assessment probe may also be advanced to the desired site for accurate placement of the stent.
