  • Patent number: 7930016
    Abstract: Tissue closure systems are described herein. Such a system may include a deployment catheter and an attached imaging 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. Additionally, the system can be deployed in a number of various ways to effect the closure of wounds or openings in the patient body.

  • Publication number: 20100292558
    Abstract: In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.

  • Publication number: 20100262140
    Abstract: Electrode placement and connection systems are described which allow for the electrical connection and maintenance of one or more electrodes positioned on a substrate which is subjected to a variety of mechanical stresses. Electrodes may also be formed on flexible circuit assemblies integrated within or along the hood. The circuit assemblies may also provide structural support to the hood during delivery and/or deployment. Such a system may include an imaging hood having an aperture through which transparent fluid is flowed and one or more electrodes positioned along or about the hood. As the hood is configured between a low-profile and opened configuration, these electrodes may remain electrically coupled despite the mechanical stresses subjected to the electrodes and the connections thereto.

  • Publication number: 20100256629
    Abstract: Methods and devices for treatment of the ostium are described herein. Examples of such devices include inflatable balloons which have one or more raised pores along a distal portion which act as conduits for providing saline flow from the balloon to facilitate visualization of the contacted tissue as well as providing for a conduction path for energy delivery. The balloon may be configured in various shapes to facilitate contact of the balloon in and against the ostium.

  • Publication number: 20100204561
    Abstract: Imaging catheters having irrigation capabilities are described herein. Generally, the device may include a first inner membrane which is sealed and serves to position the device within or relative to a lumen. This balloon structure, when filled with fluid, expands and is engaged in direct contact with the tissue. A second (outer) membrane is not completely sealed and instead provides a pathway for delivery of fluid at the treatment site for effecting various treatments. Imaging systems, optionally articulatable, may be positioned within the balloon as well as electrodes positionable upon the balloon may be utilized to facilitate tissue treatments.

  • Publication number: 20100010311
    Abstract: Methods and apparatus for efficient purging from an imaging hood 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.

  • Publication number: 20100004633
    Abstract: Catheter control systems which facilitate the tracking of an angle of deflection of a catheter distal end can be used for any number of procedures where catheter orientation relative to the body is desirable, e.g., in transseptal access procedures where an accurate angle of puncture of the septal wall is desirable. Such control systems may comprise a steerable handle which is oriented relative to the catheter steerable section to provide for consistent catheter articulation upon corresponding manipulation of the steering ring. Another variation may utilize an orientation indicator to track the deflectable distal end. For instance, an orientation marker as visualized through an imaging hood on the distal end may correspond to identical orientation markers on the control handle such that articulation of a steering mechanism in a direction relative to the orientation markers deflects the catheter distal end in a corresponding direction relative to the visualized orientation markers.

  • Publication number: 20090275799
    Abstract: Axial visualization systems which utilize axially aligned imaging instruments for visualizing through an imaging hood purged of blood via a transparent fluid are described where an imaging element extending from a support shaft may be aligned within a working lumen defined through a deployment catheter. The imaging element may be positioned distal to the hood in its collapsed state and within the hood in its expanded state. The imaging element may be configured to seat itself securely within the catheter or to angle itself to adjust the viewing angle. Additionally, a disposable visualization sheath having a transparent lens may also be utilized to house an imaging instrument therein.

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. An electric current may be passed through the fluid such that it passes directly to the tissue region being imaged and the electrical energy is conducted through the fluid without the need for a separate ablation probe or instrument to ablate the tissue being viewed.
