    摘要： Transmural subsurface interrogation and ablation apparatus and methods are described where tissue to be ablated is monitored while under direct visualization for tissue parameters (e.g., temperature and impedance) prior to, during, or after ablation. 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 the 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 can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An ablation probe and one or more interrogation needles having sensors are advanced into the tissue to be ablated and monitored. Alternatively, a combined ablation and interrogation probe may be used.

    摘要： 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.

    摘要： Tissue visualization device having a fluid barrier is described herein where an imaging hood is temporarily sealed against a region of tissue to be treated while under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. The imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A field of view of the imaging element can be expanded and the blood can also be purged in part by inflating a balloon beyond the imaging hood where the balloon is integrally formed along an interior surface of the hood.

    摘要： Tissue visualization devices having multi-segmented frame are described herein where such devices may utilize multiple expanding frame members coupled to a flexible deployment catheter shaft or rigid 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 field between the frame members. 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. Additionally, any number of therapeutic tools can also be passed through the catheter or shaft for performing any number of procedures on the tissue for identifying, locating, and/or treating tissue.

    摘要： Tissue visualization device and method variations are described herein where an imaging hood is temporarily sealed against a region of tissue to be treated while under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. The imaging hood is placed against or adjacent to the tissue to be imaged in a body linen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid is pumped into the hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via all imaging element. Temporary sealing against the tissue can be achieved in a number of ways such as circumferential balloons inflatable within the hood or other sealing techniques. A field of view of the imaging element can be expanded by inflating the balloon beyond the imaging hood.
