  • Patent number: 10772492
    Abstract: A method of inhibiting flow of a purging fluid from a device comprises positioning an imaging hood in proximity to a tissue region to be visualized. The imaging hood includes a distal membrane which defines a main aperture. The imaging hood and the distal membrane define an open area. The method also comprises introducing the purging fluid into a proximal portion of the open area. The proximal portion is bounded by a proximal membrane including a plurality of apertures. The method also comprises pressurizing the proximal membrane with the purging fluid to a partially extended state in which the purging fluid flows through the plurality of apertures and through the main aperture. The method also comprises pressurizing the proximal membrane with the purging fluid to a blocking extended state in which the proximal membrane obstructs the main aperture to block the flow of the purging fluid through the main aperture.

  • Publication number: 20190314007
    Abstract: An apparatus for inhibiting tissue migration during a procedure comprises a deployment catheter defining at least one lumen therethrough and a non-inflatable hood projecting distally from the deployment catheter and defining an open area. The open area is in fluid communication with the at least one lumen. The apparatus also comprises a visualization element disposed within or along the non-inflatable hood for visualizing tissue adjacent to the open area. The apparatus also comprises a tissue grasping end effector positioned within the open area and configured to temporarily engage the tissue adjacent to the open area such that distal migration of the tissue relative to the barrier or membrane is inhibited.

  • Patent number: 10368729
    Abstract: A method of inhibiting a flow of a purging fluid from a tissue visualization device comprises positioning an imaging hood attached to a distal end of a flexible elongate shaft in proximity to a tissue region to be visualized The method also comprises introducing the purging fluid into an inflation member suspended within an open area of the imaging hood. The inflation member includes at least one aperture on a proximal portion of the inflation member. The method also comprises inflating the inflation member to a partially inflated state in which the inflation member is circumferentially separated from an inner surface of the hood to form an annular flow path for the purging fluid from the at least one aperture, between the inner surface of the hood and the inflation member, and into fluid communication with an environment external to the hood.

  • Publication number: 20190046013
    Abstract: In one example, a system includes a deployment catheter defining at least one lumen therethrough. The system further includes a balloon member projecting distally from a distal end of the deployment catheter and defining an area therein, wherein the area is in fluid communication with the at least one lumen. The system further includes a first opening at the distal end of the balloon member, a first instrument lumen extending through the balloon member from the distal end of the deployment catheter to the first opening, and a visualization element disposed within the balloon member for visualizing tissue external to the balloon member.

  • Patent number: 10092172
    Abstract: Complex steerable catheter visualization and tissue manipulation systems and their methods of use are disclosed herein. The deployment catheter is articulated using various steering mechanisms. Tissue visualization is accomplished from the visualization hood at the distal end of the deployment catheter, the hood having an ability to expand and other features to facilitate visualization and articulation at the tissue surface.

  • Publication number: 20180228350
    Abstract: A method of visually locating a vessel within a body lumen comprises displacing an opaque fluid with an inflatable member contained within an open area of a barrier or membrane. The method also comprises positioning the inflatable member against or adjacent to a tissue region at a first location and visually assessing the tissue region at the first location through the inflatable member. The method also comprises repositioning the inflatable member against or adjacent to the tissue region at a second location.
