  • 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.

  • Patent number: 10470643
    Abstract: A computer implemented method comprises activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position. The control mechanism includes a first indicator associated with the first direction. The computer implemented method also includes obtaining an image from the distal end of the catheter of a tissue region of interest within the body and calibrating a first rotational motion of the catheter handle with a rotational motion of the image. With the catheter handle in a second rotational position that is different than the first rotational position, the control mechanism activated in the first direction with respect to the user moves the distal end of the catheter in the second direction.

  • Publication number: 20190320889
    Abstract: The present technology relates generally to devices and methods for intravascular evaluation of blood vessels. Many embodiments of the technology relate to the intravascular evaluation of blood vessels before, during and after creation of autologous valves. In one embodiment, for example, the present technology is directed to a method comprising intravascularly delivering a delivery catheter to a target location adjacent a vessel wall and engaging the vessel wall along a portion of the delivery catheter. The method can further include determining the location of a first circumferential periphery of a dissection pouch formed within the vessel wall, determining the location of a second circumferential periphery of the dissection pouch, and determining an angular width of the dissection pouch based on the location of the first circumferential periphery and the second circumferential periphery.
