    摘要: 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.

    摘要: Epicardial access and treatment systems are described herein where such devices may utilize multiple expanding frame members coupled to a flexible or rigid deployment catheter shaft. The multiple frame members may extend distally to collapse into a low-profile configuration and may further expand or open radially to create a working or surgical field under direct visualization and defined by the frame members and surrounding membrane while retracting any surrounding tissue. Moreover, the distal ends of each frame member may be tapered such that the frame members may close tightly relative to one another forming an atraumatic end. Any number of therapeutic tools can be passed through the catheter for performing any number of procedures on the tissue.
