    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.

    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: The attenuation or isolation of environmental parameters on a gastric lumen is described herein. Once tissue plications are formed into a gastric lumen or sleeve within a stomach, the newly formed lumen is subjected to a multitude of fluctuating stresses or pressure from food or fluids passing therethrough, from naturally-occurring contractions, and/or from changes in pH levels from caustic stomach acids and hormones. The tissue interface between these plications can be isolated from such environmental fluctuations, or the fluctuations can be attenuated, by a number of methods. One example is to place a gastric stent or sleeve within the newly formed lumen. Another example is to utilize multiple rows of anchors, clips, or sutures along the interface. Alternatively, bio-adhesives can be dispensed to buttress the tissue interface. In another variation, the tissue can be approximated in different configurations which effectively reduce or isolate the adhered tissue region.

    摘要: Methods and apparatus for preventing tissue migration or tissue “tenting” during transseptal access procedures are described. The underlying tissue wall may be temporarily engaged via any number of mechanisms, e.g., engaging teeth or projections, threaded needle, vacuum, etc., and one or more instruments may be passed through the tissue wall while maintaining engagement with the tissue to provide a counter-traction force. The procedure may be accomplished while under direct visualization within an imaging hood placed against the tissue surface and purged of blood.
