    摘要: Visualization and treatment of tissue regions via percutaneous access methods and devices are described herein. The system may include a deployment catheter and an expandable imaging hood. In use, the hood may be introduced from outside the patient body through a percutaneous incision and advanced through a subxiphoid pathway, for example, to the heart where entry may be accomplished via an incision through the left atrial appendage. Once within the heart, the hood can be advanced to any chamber to visualize and/or treat tissue by placing the hood against the tissue to be imaged and pumping translucent fluids into the 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, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for treating the tissue of interest.

    摘要: A method of inhibiting tissue migration comprises positioning an open area of a hood against or adjacent to a tissue region. The method also comprises displacing an opaque fluid with a transparent fluid from the open area. The method includes engaging a portion of the tissue region within the open area via an end effector advanced through the open area and which grasps onto the portion. The end effector includes a tapered section, tapered along its entire length, through which a lumen extends. The tapered section includes threads extending from a surface of the tapered section in a direction orthogonal to the longitudinal axis. The tissue region is pierced while displacing the opaque fluid with the transparent fluid through the distal opening of the hood and while maintaining engagement of the portion of the tissue region such that distal movement of the tissue is inhibited.
