Abstract: Systems, devices, and methods for locating a geometric plane within a patient's vasculature, for example, an entry plane to a valve, are disclosed. In one example, a medical device can include a body member and an expandable element. The body member can extend along a longitudinal axis of the medical device and at least partially define a lumen. The body member can include at least one opening disposed in fluid communication with the lumen. The expandable element can include at least two radiographic markers and can be movable between at least a first configuration and a second configuration. The at least two radiographic markers can be disposed within the lumen when the expandable element is in the first configuration. The at least two radiographic members can be disposed outside of the lumen and can be radially offset from the longitudinal axis when the expandable element is in the second configuration.

Abstract: Systems, devices, and methods for removing plaque from a patient's vasculature. In one example, a medical article includes a catheter body and a dissection tip. The dissection tip can move between at least a first position and a second position and can be biased to expand radially from a longitudinal axis of the medical article when the dissection tip is moved from the first position to the second position. In one example, a dissection member includes a dissection tip and a receiving space. The dissection tip can radially adjust to circumferentially maneuver between a core of plaque and a patient's vasculature. The receiving space can receive at least a portion of a core of plaque that passes through the dissection tip.

The dissection tip can move between at least a first position and a second position and can be biased to expand radially from a longitudinal axis of the medical article when the dissection tip is moved from the first position to the second position. In one example, a dissection member includes a dissection tip, a receiving space, and a severing element, such as, for example a thrombus-breaking element. The dissection tip can radially adjust to circumferentially maneuver between a core of plaque or a blood clot and a patient's vasculature. The receiving space can receive the plaque or clot that passes within the dissection tip. The severing element can at least partially sever or break apart the plaque or clot.

Abstract: Systems and methods are disclosed for creating aerial messages using multiple aircraft. Each of the aircraft includes a control box located in the aircraft for receiving data from and transmitting data to a software program running on a main computer. The systems and methods employ a wireless network to transmit and receive data between the aircraft and the software program, with each aircraft (or its respective control box) representing a node on the wireless network. Additionally, the systems and methods may operate on remote controlled devices, such as miniature remote controlled aircraft, and may be used to produce colored aerial messages. The systems and methods may be used to create an aerial vapor screen capable of displaying projected images.
