Abstract: A machine detects a set of first control operations and, in response, causes a display screen to present a graphical interface in which a central window suggests first content by presenting a first preview and a first identifier superimposed on the first preview. The machine then detects a second control operation that indicates dismissal of the first content. In response to the second control operation, the machine causes the display screen to present a transition to an interest-improved version of the graphical interface. The transition includes sliding the first preview, the first identifier, a second preview, and a second identifier together in a shared direction and at a shared speed within the central window. The second preview and the second identifier correspond to second content. In the interest-improved version of the graphical interface, the central window suggests the second content by presenting the second preview and the second identifier.

Abstract: A coaxial stabilizing and sealing catheter provides increased support to a guide catheter that is seated in an ostium of a branch artery by extending through and out of a distal end of the guide catheter and anchoring in position within the branch artery that is being treated. The stabilizing and sealing catheter includes, as part of a relatively flexible distal section, a balloon that locks a distal end of the stabilizing and sealing catheter in place to provide support to therapeutic devices that are introduced and further seals the branch artery to prevent blood from entering the branch artery. A sealing cuff at a proximal end of the stabilizing and sealing catheter provides a seal between an exterior of the stabilizing and sealing catheter and an interior of the guide catheter. In addition, a fixing mechanism is utilized to lock the guide catheter in place to exchange therapeutic devices.
